I am also having this problem...

I bought a HydroFarm heating mat for them...but it is no match for the cold temps...If I dont figure something out...my plants are dead

The stupid ass temps have stopped all growing, they have been the same hight for 3 weeks now.

I have some plants that are on week 8 of flowering...they have been the same size since week 5...at this rate...they should be ready at week 35
stupids Reviewed by stupids on . how to keep the little guys warm? ok i live in a cold country and the plants are in an unheated place in the house. the grow light has been on up till now (keeping the temperature up) but pretty soon i'm gonna need to leave the light off for periods. what is the best way to maintain the temperature at a nice level while still providing the required darkness? a portable heater is not an option. thanks Rating: 5
