Lights, ballasts, control and power

Lumatek supercool 400HPS

The SuperCube uses a 400W High Pressure Sodium (HPS) SuperCool Lumatek dimmable, full spectrum light - an air-cooled grow light with a digital ballast that also features ‘Smart Volt’ and works on both 120 and 240 volts. You have complete control over the amount of light your plants receive. The light is set on easy to adjust yo-yo’s so you can continually adjust the height of the lights over your canopy. The lighting system uses a 6” tempered glass light tube plus reflector, further ensuring your lighting is always the ideal height above your canopy.Thanks to the efficient ballasts this system uses, you can expect to use up to 20% less energy and you won’t have to worry about power surges anymore. The SuperCube runs on a standard 110 volt outlet using a single plug.A SunliftTM reflector suspension system makes for easy adjustment of the hood height. This system works with tension strings that securely hold the position of the hood in place. A pair of Sunlifts can support 22lbs .Inside the unit are magnetic, mold-repellent reflectors. These are removable for both easy cleaning and re-positioning so you don’t lose precious lumens.The 120 volt power cord provided with the SuperCube is 8ft long.The SuperCube also comes with a GFCI Shock Buster. This is an extremely important piece of equipment to have when dealing with water and electricity in close proximity. It prevents electrical malfunctions by shutting off the electrical supply to your Grow Box of a power surge is detected.

Air Movement, air filtration, heat and odor control

The unit is both light and odor tight. It comes with an activated carbon filter made by Odorsok. This filter ensures that your unit is 100% odor-free and lasts a good 2 years before it needs changing, which is easy to do.The 4 ½ inch internal circulation fan has two settings, and provides 100 and 160 Cubic Feet Per minute (CFM) of airflow for your plants. This airflow is crucial as it recreates a natural breeze for your plants that ensures the stems grow thick and strong and can support a lush canopy without struggling as well as increasing your yield potential. It is a quiet fan, enhancing the stealth aspect of your Grow Box.

Internal circulation fan

The fan is fully-adjustable so not plant in your Grow Box needs to go unattended – no need to have any more dying plants in the corners of your unit as this fan can reach every part of it.An optional CO2 Package is easily integrated and not only makes your plants grow faster, it also can increase your yields by 20-50%.

Hydroponic system – how does it work?

SuperPonic system

The SuperCube is a single chamber unit, meaning that the vegetative/cloning cycles and the flowering/harvesting cycles take place within the same space. It comes with a 10-gallon reservoir and uses the SuperPonics system.The SuperPonics system is a fully-automated watering system, using 4 proven watering methods (Deep Water Culture, Top Feed, Aeroponics and Bubbleponics) as well as both a water pump and an air pump. It is easy to set up and allows for a 2-5x better rate of growth than any single method system. The use of both a water pump and an air pump means that if one system were to fail, your plants have a much better chance of survival as one system would be able to partially compensate for the other.

Eco 2 Air Pump Air Pump - The air pump is the Eco Air 2 – an ideal pump for keeping your nutrient solution oxygenated, which is crucial for ensuring your plants thrive. The variable output feature means you can adjust how much air your plants get. It is powerful and durable while still being extremely quiet.

grow box water pump Water Pump - The water pump for the SuperPonics system is a 185 gallon per hour pump with an oil-free, magnetic rotor. This crucial component constantly circulates fresh water, keeping your plants healthy and happy. It is quiet and reliable thanks to high quality bearings and a ceramic shaft. All you need to do is hook it up to your timer and you’re set.

This Grow Box comes with the Supermini cloner. You simply add seedlings or clones to this and when ready, move your plants to the SuperPonics system. With this system, you can continually vegetate, flower and harvest.An adjustable net trellis supports your plants as they grow, and improve your plants’ growth by up to 40%.It is an incredibly low-maintenance system that you can fully automate. Requires minimal cleaning only - you won’t have to deal with any clogged drippers or dead plant matter.
