If I got a 200w dual spec cfl how much heat would it give off and how high would i need to put it above the plant ? *Too Much Heat From CFL
check my grow. i made a hangar of CFLs from 3 footers. can turn on/off any of the 1-9 lights for heat/light intensity. indispensible for my babies leading up to MH. gives them a nice ease into the HId light. the large 200 watt CFLs you want are fairly inefficient from what i understand, and because they are think make alot of heat with little spread.
Took apart the cfl Bought a socket that plugs into a outlet there like 97¢ or a dollar at walmart, ran power cords to bulb
