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.

thanks for info. why did you insulate? everything I've seen says to
ventilate. I assume the temps when closed would be similar to that of a
parked car with windows up.

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

I don't understand ... i was just thinking of sterlizing pots (without
soil) during the end of summer for use during winter for seed starting.

but, this is rather labor expensive, too

yikes :-)
