I heard to keep the light close so the lights are no more then 6 inches away. Today I went to water them and I discovered that out of 5, 2 are indeed dead at this point and the remaining 3 don't look like my friends who only planted a week or so before I did. The oldest plants don't look so well anymore. I think the problem may be with the weather. My grow room is up in the attic without direct temp control. I guess I thought the temp wouldn't get down low enough to bother them, but I am starting to second guess that now. Last week the temp dipped into the 40's outside so I would have to assume my plants at least approached 50 to 60 degrees. I think this was too much. I'm thinking I need to enclose the space in the attic with dry wall or just plastic maybe. Then I can put a small heater and fan in there to more directly control the temp. At what point is the plant in danger in terms of temperatures? We don't normally worry about freezing temps but lately the weather hasn't been so nice. I thought the plants would be ok in the attic...how cold can it really get up there if the outside temp is 45?
Prodaytrader Reviewed by Prodaytrader on . I think I killed them! I discovered recently that my timer was set to 24 hours of light with no dark. My plants shot up nice and tall and then sort of just fell over! I discovered the mistake, propped up the plants and now I wait. I do have new growth but if the stalks don't fatten out and the roots take hold I may end up in trouble. I think out of the 5 that I recently started, maybe 1 or 2 will survive. And who knows if any of them are even females. Rating: 5
