last year before i had knee surgery, i played around with 4 ft lights and had very good results, actually it the only way i will start plants from now on. last year was later in the spring. my building isn't heated when i am not there,
here in ky who knows what tomarrows temp will be, it was 65 sat and snowing today. i made a box for my lights, it is insulated with 2 layers and i have access holes to cool it down, i can remove all layers for later, when temp are warmer. i just started seeds this weekend what is the max temp, i should shoot for and the min. for starting the seeds, before i put trays in there all lights on i had 90, but that is before it cooled down, nows the temps is in 80-85, do i need to cool it down during the time my seeds are sprouting.
