does anybody stick their seed starting pots / other garden
paraphenalia in a minigreenhouse or cold frame during the summer to
sterilize them?

Is it a dumb idea, waste of time or what? As it is, I don't bother
washing, but if I'm going to have a cold frame, i would if it might be
useful outside of winter anybody know what temperature plastics will
start melting at? Cold frame will have real glass.


i trid it years ago. i used a cooking thermometer to measure temps. it
got very hot. plastic pots melted. my box was insulated wiht cardboard
then styrofoam,. the cardboard managed to keep the styro from melting.

it's not easy to keep the top surface of the mix moist. maybe putting
the mix in closed metal pans solves the problems?

but, this is rather labor expensive, too
