Heated planters?
Most plants grow a LOT better when soil temperature
is above 60 F. 2 gallon heated planters -- does anyone make them? I'm tempted to roll up a seedling mat and place it into the pot before pouring in soil, but I'm not sure that wouldn't be a fire hazard -- maker Hydrofarm says not to place insulating materials on top of the mat. |

The 10 x 20 Hyrdofarm mats have internal thermostats, will cut off at 85 F. 2 gallon heated planters -- does anyone make them?

Needs to be kept moist to keep insulation value low, not really a problem for me. Dry perlite looks like a near-perfect insulator. i think having a part of the mat overlap another part would be a worse spot-overheat pitfall. Be sure to pack soil in between the ends. |
