My plants stems are redish purple with at the bottom of the stem green, they are only 2.5 in tall and this is my first time. Is this normal??? please help me out
I have a setup that allows me to pump in cooler air from a crawl space beneath my grow area. I use a fish tank air pump and it works very well. It lowers the temp between 15-20 degrees.the lights are about 2.5-3 inches away there 2 48 inch flourescent, the light fixture is hanging and then its surrounded in aluminum foil then at both ends i have 2 fans blowing air in. i was just reading and i'm scared it might be heat stress, i'm going to try to get some pictures up of the plants, the temp is around 90 degrees F, and humidity 45% if you could help me with an idea how to cool the area down that'd be great
