Stick a 'seedling heat mat' under your plants. Low temps will make any soil problems MUCH worse, slow growth, and decrease yield. You can get the mat at any good garden store for $25 USD.
stinkyattic Reviewed by stinkyattic on . Lower temperature question I am on the east coast and recently the temps have been pretty low. The temperature inside my grow box has been staying 60-70 degrees sometimes falling to 50s during the night (which the lights are still on.. my light cycle is 5:30pm to 11:30am), will this adversely affect growing or will these temporary lower temperatures be alright..?
