run an extension cord out to the grow and put a space heater on them. Just camo the heater so it dosent look suspicious
My first grow was 1976. Outlaw grow about 15 miles from my house. I had noticed my dads compost pile steaming one day and viola!!! Built tent and carried 4-5 buckets of my dads pile to my grow.ive got lots of horse manure. i should give that a try never really thought of using clippings and horse manure to produce heat.
right now i use nothing but horse manure to grow my plants
I do have a pic of it in 76' somewhere I'll try and get it on here.i wasnt even born than lol
would putting my plants between a couple big boulders help against frost
