Re: [IGSROBIN] Heat box for starting cuttings


Its not all that hard to do a heat box, but do you really need to?  In San
Diego you will have warm enough temps to root about anything.

However, if you insist.  The coils are waterproof, so no worry about
watering them.  Pearlite is ok, although I like sand and vermiculite better.

Build the boxes out of 1 x 4 cedar, or other wood.  Pallet lumber works
fine.  Put the coils in at the bottom, add the planting mixture at about 4"
deep, water well, and put in the  cuttings.  I only run the heat when the
air temp is less than 60 degrees F.

When you put in the coils just snake them around to cover the bottem evenly.

Good Luck.
