keep it high enough for the pots or hydro setup, plants distance between plant without burning them, distance to grow and space for the light. remember to vent the heat and light sould not be a problem cause it sould be air tight (except for in out take) and light proof you dont want light coming in during the dark period. a 400 or 600 watt system will work well try to get a air cooled hood it will help with heat and safty. good luck keep us posted
imagoober Reviewed by imagoober on . Rookie Grower 1. How much more on your energy bill for a 400 watt Sodium light? 2. If I were to create a 4x4 box in a room, would I really want to line it with tin foil on the inside? Is that 400 watt light enough for 6-8 plants? I worry about the neighbors seeing these lights on, thats why I wouldnt want to make the whole room a grow room. Any suggestions to get me going. Rating: 5
