If I had a grow chamber that was set at 75 or higher and a tomato or pepper sprouted in less than week how will low temperature outside the grow or sweat box effect it after it sprouts? I am talking of temp at between 32 and 40 at night and a little higher in the daylight! Once it sprouts is the light the most important thing or the temp or both? Will the low temp make the plant stronger in the long run as long as there is alot of light in a greenhouse? Slowing the stem or leaf growth rate down by a lower temp could give a better root growth or not?
I noticed when plants grow too fast they are thin so I am wondering what is the perfect temp after sprouting?
