Lights, Ballasts, Control and Power

  • LEDs do not require a ballast which saves around 100 Watts of power on the average HID unit;
  • The main flowering chamber of the LED SuperNova contains a KIND K3 Series LED grow light;
  • SuperCloset offer the Kind K3 L600
  • The KIND LED panel is a powerful, high performance LED grow light and an upgrade on the LED panel previously supplied with this grow box;
  • KIND K3 L450 has 8 separate modules, each containing 15 non-dimmable 3W diodes = 120 individual high powered LEDs. Read down further for our analysis of this LED.
  • KIND K3 L600 has 10 separate modules, each containing 15 non-dimmable 3W diodes = 150 individual high powered LEDs. Read down further for our analysis of this LED.
  • Claimed footprint for L450 = 3’ X 4’: Footprint for L600 = 3’ X 4.5’;
  • Actual size of each model Kind LED Grow Light. L450 = 20” X 11” X 3”: Actual size of L600 = 25” X 11” X 3”:
  • Custom designed 12 band light spectrum is ideal for photosynthesis at all stages of plant growth. Take a look at our full spectrum LED article.
  • Super long lasting diodes have a life rating of 50,000 hours;
  • Diodes run at a high performance 700mA;
  • 2 CM, heavy duty aluminum circuit boards and large cooling fans dissipate heat efficiently, extending the life of the unit and keeping grow box temperatures down;
  • “Secondary Optical Lens” optimizes Photosynthetically available radiation (PAR) and increases light penetration into the plant canopy and below, enhancing ‘sub canopy’ production;
  • 3 year warranty;
  • YoYo hanging system allows you to position the light at the correct level, basically as close to the plant tips as you can get it;

LED Grow Lights

LED lighting systems are a big investment. You should take some time to do the research on different systems and find out how they work. Check out the following articles: Some of the information from KIND is difficult to follow but our calculations are:LEDs are typically low voltage devices operating at forward (V) voltages of 2 to 2.8 as shown at the bottom of page two on the PDF above and IF (Forward current = 0.7A – 700 mA). (The letter I stands for current in Amps in electrical calculations) Power P = VIThe K3 L450; 15 X 3Watt LEDs in each section, then there are eight sections = 120 LEDs in total. Take the above data (assume VF = 2.25 V) as Kind say and IF = 700mA (so power = V*I =2.25*0.7 = 1.575 Watts per LED) and go from there. e.g. 120 LEDs = 120*1.575 = 189 Watts. So we believe the actual draw is 189 Watts.SuperCloset offer the K3 L600; 15 X 3Watt LEDs in each section, then there are ten sections = 150 LEDs in total. Take the above data (assume VF = 2.25 V) as Kind say and IF = 700mA (so power = V*I =2.25*0.7 = 1.575 Watts per LED) and go from there. e.g. 150 LEDs = 150*1.575 = 236.25 Watts. So we believe the actual draw is around 236 Watts.KIND talk about 3W type LEDs (like the specs above) but they’re clearly not operating them at that level, this would be like running your car engine at full revs all the time and would limit the life expectancy of the LEDs.

Air Movement, Air Filtration, Heat and Odor Control

  • Super cool LED lighting dramatically lowers the need for any heat ventilation in the LED SuperNova grow box;
  • Twin industrial grade carbon filters make sure that the exhaust from the LED SuperNova is guaranteed to be odor free, essential for stealth grows;
  • Two powerful and quiet air pumps combine to provide 440CFM of air exchange, constantly refreshing the air in the cabinet and removing stale used air;
  • Internal air circulation is provided by a powerful fan that circulates the air at up to 160CFM. Moving air around your plants is crucial for strengthening stems and branches. It also helps keep humidity down, preventing mold.

Hydroponic system – How does it work?

The LED SuperNova Grow Box comes with dual chambers. This means that you can set up your system as a Full Cycle Rotation System. With this set up you are able to cultivate plants at all stages of growth simultaneously. Whilst one batch of plants is ready for harvest you can have others at varying stages, from seedling to flowering. With a little planning it is easy to set up a continual harvest system that will give you a regular supply of herbs.The Flowering Chamber
  • The LED SuperNova includes an award winning SuperPonics 16 system. This high performance hydro system combines Deep Water Culture, Bubbleponics and Top Feed Watering to bring you a combination of the best hydroponic grow systems available;
  • Using a SuperPonics combination system has been proven to outperform single systems by up to 200%, and soil systems by up to a massive 500%;
  • Spacious 15 gallon nutrient reservoir is made from UV stable, FDA approved materials;
  • SuperPonics system is run by a powerful 185GPH (Gallons Per Hour) water pump. This oil-less pump features a magnetic rotor with ceramic shaft and bearing to ensure a reliable and operation;
  • SuperPonics system is equipped with an easy change valve system. Changing your nutrient solution has never been so easy, just turn the valve to empty the spent solution;
  • Air for the hydroponics system is supplied by an Eco Series air pump. SuperCloset supply the Eco Air 4 which has 4 outlets and provides 640lph. Despite the difference, both are adequate for running this system.

  • SuperCloner 50 fully automated hydroponic cloning system. This system uses a combination of Deep Water Culture (DWC) and bubbleponics to nurture your delicate clones until they have developed a strong and effective root system. You can even leave clones in there until they are ready for flowering!
  • The SuperCloner 50 measures 28” X 22” X 6”. This is enough space for 50 clones seedlings or young plants;
  • The cloning chamber also contains a dedicated Mother Station. This smaller, 8 site SuperPonics system, provides enough space for up to eight mother plants or vegetative plants;
  • Use the Mother Station to keep a variety of mothers for different strains, or use it for a bit of extra vegging – the more veg you give it, the larger the yield;
  • The Mother Station operates using the same combined SuperPonics system as that found in the main flowering chamber.

“I thought the led phenomenon was all hype. Boy was I wrong. I did a lot of reading and then settled on buying the led super nova. My yields have increased by half as much again and my bills have dropped. Amazing.“

“LED all the way! There so cool they almost touch my plants without burning them. The plants love them and so do I!”

“I was a total beginner at growing so thought it would make sense to buy a grow box rather than messing about myself with stuff I don’t understand. It is so easy and the quality of the bud I now produce is much greater than I was paying top dollar for just a year ago! Why pay for it when it is so easy to grow your own?”
