Lights, Ballasts, Control and Power

  • No ballast required with LEDs.
  • The SuperFlower 3.0 LED grow box is equipped with a KIND K3 Series L450 LED grow light;
  • K Series KIND L450 grow light performs the same as a 450W HPS. See our notes below of the LED lights and also read our reviews before buying grow LEDs.
  • 8 modules with 15 diodes per module makes a total of 120 high powered 3W diodes. This does not equate to 360 Watts of power, actual draw will be around 50% of that – see our math below.
  • Proprietary designed 12 band spectrum works in harmony with your plants’ photosynthetic requirements;
  • Much more economical that HIDs - bulbs rated for 50,000 hours of use;
  • Non dimmable diodes run at 700mA, more powerful than lower end units;
  • Recommended footprint for optimum performance - 3' x 4';
  • Unit size – 20” X 15” X 3”
  • Heavy duty 2 CM aluminum circuit boards, combined with efficient large fans, dissipate heat effectively. Still use internal fan though;
  • “Secondary Optical Lens” magnifies PAR values and increases light penetration through the plant canopy, increasing “under canopy” production;
  • 3 year warranty;
  • As well as the powerful L450 grow light, the SuperFLower 3.0 LED grow box also contains 2 X 24W T5 supplementary side lights. These lights will improve vigor and increase yields.

LED Grow Lights

Before investing in any LED lighting systems you should take some time to do some research. Check out the following articles: Some of the information from KIND is difficult to follow but our calculations are:Both offers use the K3 L450; 15 X 3Watt LEDs in each section, then there are eight sections = 120 LEDs in total.One respected commentator (with a PhD) who wanted to remain anonymous stated:

“LEDs are typically quite low voltage devices operating at forward (V) voltages of 2 to 2.8 as shown at the bottom of page two on this PDF and IF (Forward current = 0.7A – 700 mA). (The letter I stands for current in Amps in electrical calculations) Power P = VI.”

“There are so many conflicting statements in what Fullbloom and SuperCloset have stated and in the KIND LED video I don’t know where to start. 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.”

Bottom-line – We believe these K3 L450 Kind Grow Lights run at actual/true draw of 189 Watts.K3 L450 KIND LED Grow LightThey talk about 3W type LEDs (like the specs above) but they’re clearly not operating them at that level, no one does, as it limits the life expectancy of the LEDs.

Air Movement, Air Filtration, Heat and Odor Control

      • The LED SuperFlower 3.0 grow box uses two large, industrial strength carbon filters to remove all odors from the exhaust, the exterior of the cabinet is guaranteed to remain odor free;
      • The carbon filters are powered by dual extractor fans that provide a combined total of 220CFM of airflow. This not only eliminates odors, it provides lots of fresh air for your plants;
      • Fans run quietly to keep the noise of your grow box to a minimum;
      • Air intakes are filtered to keep bugs, spores and pests out;
      • Internal air circulation is important to keep your plants healthy and strong. The LED SuperFLower 3.0 features a powerful, dual speed, 4.5” internal circulation fan. The fan has fully adjustable height and tilt. It also features adjustable speed (either 100CFM or 160CFM).

Hydroponic system – How does it work?

The LED SuperFlower 3.0 is a single chamber grow box. Flowering and vegetation must all be carried out in the same space. The 12 band LED grow light makes this easier than with HID systems as there are no bulbs to change when transitioning between veg and flower.At the heart of this growing system is the famous SuperPonics 16 site hydro system. SuperPonics uses a combination of hydroponic methods to get the best out of the space you have. By combining hydroponic methods, SuperPonics can result in yields up to 200% greater than single hydroponic systems, and 500% greater than soil systems.
      • Combines top feed, deep water culture (DWC) and Bubbleponics;
      • UV stable 15 gallon reservoir and lid;
      • Quiet and efficient dual outlet Eco 2 air pump runs at 4W and provides 4.5 liters of air per minute;
      • Eco-185 water pump operates quietly and circulates up to 185 gallons of nutrient solution per hour;
      • Easy change valve system makes changing your nutrient mix hassle free;
      • 3” net pots for support;
      • Clay grow rock growing medium.
