Growing cool-season vegetable under metal halides

12 years ago

I'm new to gardening and am planning to grow some leafy greens indoor. I posted a while back about using indirect daylight from my north-facing window, and realised it will be insufficient to grow any plants at all. So I'm now planning to add several metal halides to supplement the window light. I had been researching on how to grow most of the greens, and noticed they are all "cool-season vegetables" (collards, mustards, cabbage...etc). From what I understand, metal halides do produce quite a bit of heat, and cool-season vegetables will bolt and taste bitter if subject to warm temps. My indoor temps are in the low-80s during summer, even if I install a fan to increase ventilation for the plants, I don't think I can get it much lower than that (maybe able to get that down to mid-70s). Do you think that is good enough to grow the vegetables listed above? There won't be any direct sunlight hitting the plant or the soil.
