Guys,
In the effort to try to keep the 3 gallon / coco roots warm during "lights off", I'm wanting to use some 10" x 20" seedling heating mats to provide *enough* heat to keep the roots warm and growing.
During "lights on", temps are perfect. It's when the lights are off that the tent temps go down to less than 15 deg C.
No.......I don't wish to heat the entire room and ambient air, with a space heater, or heat the inside of the tent with a space heater.
So back to the heating mats.......
I have two options as to where to place the heating mats.
1] Under each grow bag.....in the hopes that enough heats gets absorbed "up" into the root zone. A possible negative with placement here is that having the mat in direct contact with the bag bottom, water run off may be inhibited. [ I currently have each bag sitting on raised drain screens ].
2] Wrap the heating mat around the outside of the 3 gallon bag. This would allow heat to radiate, with contact, to the side of the bag / roots. The positive......the bags can still drain freely whilst on the drain screens. The negative........the heating mat may inhibit air-flow through the sides of the bag.
Hummmm.
Anyone done this?
Do you think there will be more heat transfer and retained heat, with the side of the bag wrapped with the mat?
Will wrapping the bag interfere with the drain to waste / air movement, enough to matter?
Which method would be "better"?
