Transcend Lighting D 200 was designed specifically to supplement greenhouse light
40k -60k
those look nice . kinda pricey @999.00 for a 600w replacement. i like how the whole pad lights up. very cool.
ive already got 1k gavita for my GH. dude lost money. i got 16em for 275 a piece. only used for 2 weeks.
As for a light dep, if you want to get plug n play kit for less than 30k. Farmtek series 500, 30' wide. has and optional blackout kit. 17k for 96' kit. and about 9k for the greenhouse. so after all said n done. 40 to 60k. if your not building it.
