Included Components

Included with Hydroponic Systems Only

12 Plant SuperPonics XL System
The SuperPonics XL 12 combines automated top feed and Deep Water Culture, assuring you the best, easiest, fastest, and safest grows over any other method. SuperPonics is the fusion of multiple proven hydroponic methods into a single system, creating unparalleled yields in quality and total. These systems are incredibly easy to use and are fully automated. SuperPonic systems grow up to 2-5X faster and bigger than any single traditional hydroponic method. SuperPonic systems are also safer due to the fact that if one of the methods goes out for any reason (air pump or water pump) your plants will still survive and thrive.

SuperCloner 50 Site System
This SuperCloner gives your new plants just what they are looking for in their early stages of life. This Deep Water Culture hydroponic system promotes rapid, luscious white root development! Germinate, clone, and vegetate up to 50 plants to their perfect transplanting condition.

Premium 4-Port Air Pump
Very quiet, yet extremely powerful. This strong and durable pump is widely used to provide oxygen in hydroponic systems and is convenient to operate without oil or noise.

185 Gallon Per Hour Water Pump
Our 185 GPH (gallon per hour) pump is the heart and flow of our unique hydroponic systems. Its powerful, oil-free high magnetic rotor, ceramic shaft, and bearing insures reliability and quiet operation. Plug it into its designated timer and you have your own personal robotic gardener making certain that your plants never go thirsty again.

Clay Grow Rocks
The simple addition of this reusable secondary medium translates into more robust plants that will ultimately lead you to greater yields. By giving your roots a course, porous, and absorbent material through which to weave, you are providing a much more solid and stable foundation, allowing your plant to grow thicker, bigger, and stronger.

Included with Soil Systems Only

Eight 5 Gallon Soil Pots & Twelve 1 Gallon Soil Pots
They’re soil buckets, what can you say? Actually, plenty. These heavy-duty pots feature a reinforced rim making them strong enough to pick up with heavy plants. They feature a side and bottom drain design for superior drainage and offer a wide base for increased stability and the development of a more robust root mass. Trust us, these soil pots are tops.

Premium Moisture Meter Take the guesswork out of knowing when your plants need water. The included Moisture Meter will quickly and accurately measure the water content of your soil at all levels in the soil pot. Easy to read display will tell you when your babies need that sweet, sweet nectar of the gods. No batteries needed.

Included with All Systems

Kind LED X420 Grow Light
Kind LED is excited to announce the latest innovation in LED Grow Lights Technology—the brand new X Series. The successor to our K3 series of fixtures, the new X220, X330, and X420 fixtures combine the tremendous innovations of our flagship X² fixture with a brand new form factor optimized for the home grower.

Seedling Tray with dome
This kit ensures that you achieve great germination success. Your humidity dome and seedling tray are the perfect home for your little babies.

Trellis System
A trellising system increases your yields up to 30%. Trellises help support, partition, and train your plants creating equal spacing from each other and assist in the formation of a nice, even canopy, ensuring even light distribution and absorption for each and every plant.

Adjustable Internal Circulation Fan
Another reason the SuperCloset is the top performing grow box on the market is because we maximize airflow. This all-important feature, which is strangely absent in other systems, recreates the wind that passes through a blossoming outdoor garden. The easily adjusted height and tilt angle allow you to always have this gentle breeze blowing the ideal height above your plant’s canopy.

Dual Industrial Grade Carbon Filters
Basil? What basil? Our seamlessly designed carbon filters eliminate all odor emanating from inside all of our products. They will last up to two years before needing replacement and ensures the air around your cabinet is as clean as your corporate office. Cleaning is easy!

Digital Thermometer / Hygrometer
This handy device gives you the ability to make certain that you are providing your plants with their ideal environment. Effectively measures indoor/outdoor temperature and indoor humidity. Stores the min/max values of your temperature and humidity. Switch between °C and °F. Clock function. 12/24 hour mode switch. Includes a waterproof temperature probe.

App-Controlled Smart Timers
Now your SuperCloset Grow System can be controlled through your smartphone or tablet. By simply downloading the app, you have access to set, customize, and control your grow light schedule from anywhere. If you choose the hydroponics option, you will also have control of the water pump timer allowing you to set the perfect top feeding schedule for your plants at any stage of growth. Never before has it been easier to move through the stages of your grow to a perfect harvest!

General Hydroponics pH Control Kit
Is your pH off today? Well, it won’t be if you use our pH Control Kit made by General Hydroponics. The kit contains 8 ounces of pH Up, 8 ounces of pH Down, 1-ounce indicator and vial. Each system comes with this kit that keeps your reservoir contents in perfect harmony.

10-Socket and 6-Socket Industrial Power Strips
Power surges and lightning strikes are not the only things that can damage your home workshop equipment. Simply switching your workshop tools on and off can create electrical imbalances that could cause cumulative, permanent damage to your valuable equipment. The two included industrial power strips provide clean, safe, and balanced power from grounded outlets.

GFCI Shock Buster
Safety first! That’s our mantra here at SuperCloset, and why we include a GFCI plug adapter with every one of our products. Extremely easy to operate and a must-have for eliminating electronic malfunctions that may occur whenever water is adjacent to electrical components.

Rock Wool Cubes
What is rock wool? Rock wool is spun granite and wicks like nothing you have ever seen before. Roots find a nice comfortable healthy home in our cubes and once they get their legs, they easily poke through to find, and latch onto the surrounding course, porous clay rocks to start a healthy and stable foundation.

NEW! Lotus Premium Plant Nutrients Sample Kit
LOTUS Premium Plant Nutrients were scientifically developed by Northern California growers with decades of medicinal plant cultivation experience. LOTUS Nutrients is a more complete, 3 part nutrient line that replaces the need for complex 8-10 part recipes. The pure, 3 part system gives your plants everything they need to for development from seed to harvest, giving you unmatched results in flowering and fruiting plants. Specifically formulated for medicinal plants and comprised of 15 unique raw, natural ingredients including 13 essential macro and microelements as well as raw materials including seaweed plant extract, humalite, and plant protein hydrolysate. LOTUS Nutrients are 100% water soluble formula milled and blended to provide perfect consistency and contains no binders, fillers, or dyes. The LOTUS Starter Kit comes with Pro Series Grow, Boost, and Bloom nutrients and will get you growing seed to harvest from day one! The Lotus Nutrients sample pack includes an 4oz pouch of Grow, 4oz of Bloom, and 2oz and Boost. This should be enough to treat over 17 gallons of water in the vegetative stage and 8 gallons in the flowering stage.

Optional Enhancements

Super CO2 kit

Includes a solenoid, regulator, timer, and injection tubing. Along with light and water, CO2 is an essential component of effective photosynthesis. Sure your plants can pull CO2 from the atmosphere, but when you spoon feed it to them in great abundance, they get very full, and when they get very full, they produce VERY full fruits and flowers for you. Introducing CO2 into your setup can increase your yields by up to 30%!

Reverse Osmosis Water Filter

Produces up to 300 GPD (gallons per day) ultra-pure, low PPM water. Removes 98%+ of chlorine and contaminants. Wastes approximately 50% less water than other RO Systems. Everything included in the box for quick hook-up. Customized for gardening and hydroponics. *Based on 77° F 60 psi, 550 ppm inlet water. Includes: 4-Stage RO Unit, 2 RO Membranes, Carbon Filter, Cleanable Sediment Filter, Automatic Shut-Off Cartridge, Wall Mountable Metal Bracket, Garden Hose Connector, ln-line Shut-Off, 8 ft. RO & Drain Line, 5 ft. Inlet Line, Filter Wrench, Instructions. Unit size: 16.5’’ x 14” and weight: 9.8 lbs. Limited 1 year warranty. Filter is ideal for well water users with iron and sulfur and city water users with chloramines.

BlueLab Guardian Monitor

The BlueLab Guardian is a great all around meter that measures all three critical parameters to successful growth; pH, total conductivity, and temperature. With its large illuminated digital display it is easy to read from a distance. While SuperCloset’s standard systems include components to check on and manage these variables, the BlueLab Guardian gives you a constant reading of all three on one super cool LCD display panel.

Method 7 LED Growing Glasses

LED lights cast an appealing space age, purple glow, and while this looks super cool in the moment, the lighting tends to have an adverse effect on your vision for several minutes following. In addition to this, the dramatic glow of these lights prohibits you from seeing your plant with its natural color, making it difficult to gauge the true condition of your plants. Method 7 has created a phenomenal solution to this dilemma, one that you must see to believe. Method 7 offers the world’s ultimate optical tool for indoor growers using LED lights, providing “Perfect Color” with the patent pending Rendition Technology. This Technology was developed so people who work under the harsh conditions of LED lighting can protect their eyes and see the full range of natural colors.

The Kind LED Difference

Kind LED has been the industry leader in targeted full spectrum LED grow lights since 2014. We’ve consulted with hundreds of professional medical growers to rigorously research and develop our proprietary cutting-edge LED technology which continually revolutionizes the indoor growing industry year after year. Kind LEDs are widely considered the best LED grow lights to maximize yields and potency on the market today.

  1. Anon.

    I hope you guys sell 100 Million of your closets. The creative folks behind your design definitely deserve a high five for the concept.

  2. Zack

    I couldn’t be happier with my SuperNova. My only problem is that my plants grew a little too quick and got a little too big 🙂

    You have a kick ass product!!

  3. Haley J.

    My Nova is OUT OF THIS WORLD!!!
    I’m going to the CUP!!

  4. Carl

    When you click on a picture on your website to enlarge it your site does not let you “x” out of it. i.e. when you go to click on the “x” in the top right hand corner it will not allow you to click on it and you are now stuck on that picture and not able to get back to your main site…….

    Just trying to help out…..LOVE your products, keep up the good work guys!!

    Hello Rory. I got the led supernova. Alsom Alsom!!!! You are my hero!!! I just want to thank you once again. I hope all is well and you have a happy, merry Xmas. Joseph.

  7. Michael B.

    Recently I placed an order for the Super Cabinet. I worked initially with Anthony and later with Matt, and finally both of them.
    I’ve been doing business at the corporate level since Moses was a corporal. I know the corporate world. Previously as an acquisition consultant, I’ve been exposed to Fortune 500 companies all the way down to very small 2 man operations.
    It has been and will continue to be a real pleasure working with your company and these gentlemen. They are professional, upbeat, solution oriented and knowledgeable.
    That added to the fact that your grow boxes are second to none…the competition must feel rather uncomfortable knowing you’re out there.

    Thanks again for your outstanding service.

  8. Sara (verified owner)

    Awesome product!
    Stealth and has everything you need. I love how big the flowering area is. Plants are happy and healthy with minimal attention.

  9. Glen

    Well if your gonna grow one plant the supernova might be allright. I got all the upgrades and can honestly say I was happy with all the products except the cabinet. I prefer using tents myself but if your looking for a small hobby grow this would be what your looking for.

  10. Brandon Paxton

    I was hesitant about 1. Going hydroponic for the first time and 2. Using LED’s for the first time. Purchasing the Supernova LED Cabinet is the best possible decision you can make for an all-inclusive grow system. Really. It lets you concentrate on maximizing your grow and not having to worry about keeping it stealth, quiet, and keeping everything working.
    The customer support is amazing. Seriously, I was online with Matt DAILY when I first got started.
    If you want a stealthy cabinet with plenty of room to grow, get this one.
    I plan on adding another SuperNova in the Spring.

  11. Valdo

    A-1 customer service since I got the supernova any question i had no matter how stupid they were there answering. The supernova works like a dream everything you needs comes in the package. My first harvest wasn’t all that I expected but we learn from our mistakes cant wait till my next harvest is ready. Thanks to Matt and the crew for making this possible.

  12. Patrick

    Awesome product and the LED lights make a huge difference. The starter nutrient system is a nice easy way to get going.
    The produce in a year’s time made it pay for itself.

  13. marrece

    I’m like a kid waiting for Christmas to come so i can open up my present…. Long time coming. I’ve been wanting one of these systems for 5 years now.
    please hurry lol

    Title: A Professional Engineers Review and Opinion
    The system comes well packaged and well protected on a pallet. The packaging is nondescript and looks very much like a large refrigerator box. In all, the shipping weight for everything was 400+ pounds. The cabinet itself is a strong commercial type cabinet with welded seams. Doors are reinforced and the lock is much better than expected. To put it simply, this is not a common and cheaply made unit typically found online or at the local Walmart, Home Depot, etc. It arrived without any damage, not even a scratch or ding.

    SuperClosets’ modifications are also quite professional with exceptional attention to detail. Weather stripping, attachments, hardware, and other attached components are above average and also top grade. The magnetic liner provides an easy off, easy on capability for cleaning. The liner has a bright white highly reflective surface which some studies have shown provides better useful reflection than mirrored reflectors. Penetrations are exacting, professional and component fit is equally impressing. All penetrations are equipped with heavy duty black PVC fittings (90 deg Elbows). This provides a smooth place to run wires without having to worry about damaging the insulation against the sharp metal cutouts. It also does a very good job of blocking light from escaping or penetrating the cabinet.

    Included components are well made and strong. The tanks/tubs are made of a heavy duty plastic/nylon/HDPE type material. These are much stronger than a typical Walmart or Rubbermade storage bin. Think of it like half way between a rubber made bin and a Heavy Duty Pelican case. The lids are made of the same material and there is a nice tight fit (so much so you may need to use a little muscle to remove the lid.) The trellis netting appears to be made of braided/twisted nylon and is held in place with 4 strong neodymium magnets.

    The light is badass. It is made of a thicker sheet metal, powder coated, heavy duty, well ventilated with the internal fans, and quiet. The filters are placed up and out of the way to maximize internal space for growing. This arrangement also allows for better cooling as it draws from the hotter air at the top of the cabinet. Both filter fans are high flow whisper type fans. The two circulation fans are not cheap either. When I first picked one up I noticed they were much heavier and better made than what one would expect. The fan cage, mount, and hardware are all metal, not plastic. They are heavy duty and continuous duty components. The LED light pulley system is also more robust than expected with ratcheting locks. Pull on the cable and it stays put. Push a release button and it moves down freely.

    The unit includes four T-5 fluorescent grow fixtures. They have magnets attached which allow for easy relocation if needed. Circulation pumps, tubing, air pumps, and their components are also professional grade. Likewise, timers, electrical components, baskets, pots, testing equipment, chemicals, etc. are all higher quality. Everything is designed for ergonomics and commercial type continuous duty. This stuff will last!

    Customer service is BEYOND exceptional. The SuperCloset crew is professional, nice, respectful, helpful, well trained and extremely knowledgable about their equipment, hydroponics, gardening, latest innovations and they truly care about their customers and our success in using their products. If you leave a message, they will definitely call back. If anything is missing, broken or malfunctioning they quickly and graciously take action to make any necessary corrections. They value, enjoy helping and getting to know their customers.

    Now for a few things that I would have added or modified:
    Wires run out the back of the unit and there are three penetrations that allow this while also providing ventilation. One at the top center, one at the lower right of the upper chamber, and another on the left side of the lower chamber. I would like to see an additional hole on the lower left of the upper chamber to help run wires so they are out of the way and more aesthetic. Also, there is a hole between the upper and lower chambers near the front right side. I feel that this hole may be more beneficial if placed at the back of the cabinet. With all that said, I’m sure that there is a better reason for the placement of these holes than I am aware of.
    The manual is a bit outdated. Also, check to see if you have magnets on the T-5 strip lights. If you do, there will not be any clips to attach the fixtures. I like the magnet system better…easier to install and you can easily move the fixtures around a bit if needed.

    A few of notes:
    The unit is a bit deeper than just the cabinet. This is to accommodate the penetrations and components that hang on the back of the unit.
    The instructions are taped to the side of one of the boxes inside the cabinet. You will need an assistant to help install the filters and move the cabinet (take everything out of the cabinet first).
    Set up and installation is much much easier than it would appear when you see everything they give you in the packages. I mean, there is a lot of stuff you get with the system. SuperCloset gives you everything you need in one package…everything except water. You will need to provide your own water (LOL).
    You may think “jigsaw puzzle” when you first open the boxes. But it’s actually rather easy to get it up and running if you study the manual first (it’s a tad outdated, but still easy to follow). In all I think it took less than 3 hours to get everything running.. The hardest part for me was moving the cabinet indoors.
    Once the system is assembled (and no water in it yet) LEVEL the cabinet. You may need a friend to help. I did it by myself with shims and a small hammer. But in some situations the cabinet may need to be tilted while a spacer is placed beneath it.
    If you need to move the cabinet on hard flooring (wood/tile/masonary) save a piece of the corrugated box to place under the cabinet. This will help slide the thing where you want it. A truck dolly will do the same, but I found this simple method faster and easier.
    Note that the unit comes freight on a pallet. This means a tractor trailer rig will probably want to get to your home to make the delivery. Make sure you have the room in your neighborhood for this. Also, it doesn’t hurt to contact the delivery company a day or so before delivery to coordinate time/route/etc.

    A few extras that will make life easier:
    Get a Reverse Osmosis water filter. This will remove most minerals, chemicals, dissolved solids, bacteria, etc. from the water. It will also lower the Ph a bit toward neutral. Use the dissolved solids meter and Ph kit that comes with the unit to test the water. If using RO water, you may want to let it settle for a bit to get a good reading on the Ph. Im using a Ph meter and not a chemical test kit. For the RO water I get erroneous readings if tested right out of the faucet. After an hour the water seems to settle down and readings are fast and accurate. If the dissolved solids are still too high for your liking, add a deionizing canister filter as the last filter in the system. This will take the ppm down to almost 0.
    Get a pair of the special color corrected glasses. They are a bit pricy, but that light is BRIGHT and in a color spectrum designed for the plants, not our human eyes.
    I found that ordering extra magnetic hooks (get the stronger ones) will really help to clean up wire routing and gives you a place to hang tools and stuff. I also found that using a strong magnetic hook makes placing and adjusting the two internal circulation fans much easier.
    The system comes with a sample pack of nutrients and chemicals. Go ahead and get the larger kit now. You’re going to need it and if ordered with the closet, the shipping cost is much less.

    One last thought. It may be “cheaper” to try and build one of these yourself. But I don’t know if it will be more economical. There is a lot going on and a lot of components. There is a lot of thought, design, trial and error, development expense and years of experience that go into this design and construction. This combined with the fantastic customer service brings a LOT of value to the table that is not necessarily reflected in the cost. There are other perhaps smaller and less expensive companies selling knock-off versions of these cabinets. But I highly doubt that they have the resources and expertise to provide the customer service SuperCloset offers. And, they may not even provide the same quality components. That, and as an engineer, I have an appreciation of intellectual property, and not those who take a good design of someone else and simply copy it. In my career field it’s called intellectual theft.

    Anyway, I hope this helps someone. Happy Gardening!!!

    Great product, definitely would recommend. Would have rated it 5 stars but it’s not that discreet do to the fans, and the space for veg it needs to be couple inches taller for growth.
