The Megagarden works great indoors, or outside in hobby greenhouses when illuminated with a Hydrofarm Sunburst Series grow light (not included), or any grow light. At the heart of the Megagarden is a super efficient flood-and-drain pump irrigation system that ensures optimal moisture control for healthy roots. The system works by pumping nutrient solution up from a reservoir to a water tray where water levels are precisely controlled. Plants are watered uniformly on a timed cycle for optimal moisture control and healthier roots.
The soilless Megagarden’s removable grow tray measures 23 inches by 23 inches square and holds fifteen 5-inch, plastic grow pots filled with, not soil, but either the included fired-clay or pebble grow media. The system comes complete a 7-1/2-gallon reservoir, submersible pump, timer (capable of up to 12 flood settings per day), rock-wool starter cubes, 16 ounces of Hydrofarm All-Purpose Nutrient, a pH test kit, and complete instructions.
