during your plants early stages of growth "veg" they like a blue spectrum of light.metal halid lamps give this spectrum .during your flowering cycle "12/12" your plants want red/orange'ish color,it signifies the end of summer and its time to start producing.hps lamps will give u this spectrum of light.now the newer ballast's u can flip a switch and change the bulb with out having to buy a 2 seperate lighting systemsso basically u get 2 lighting systems in one.personally i just use conversion bulbs but i also run much larger lighting systems than a 150 or 250 watt .
disrupt86 Reviewed by disrupt86 on . need insturctions on building a grow room this was my first year growing and i grew two successful plants outdoor. they have been chooped for a week now and i already miss having plants so i decieded to try indoor, though i have no clue where to start. complete noob. i have a closet about 4x4 where i plan to use as my grow room. i plan on having 2 or 3 plants (clones from the local club) seeing as i have limited space and that will be plenty of ganja for my own personal use. the closet is about 6 feet tall with 2 removable shelves.
