: So these gardners on some other boards are talking about using
: "milkhouse" heaters to heat their greenhouse hoophouses in the
: winter. I looked them up, they are just the little non-glowing ceramic
: space heaters like I have in the bathroom. If they tip over, they shut
: off. They're about $35 or less.

You will need lights strung across the top to see, and then a heater or two will keep the temp up while you are out there... Shut the heater off after glassing and leave the lights on to keep a few *'s of heat for curing.

: Gonna set up this weekend and see what I can maintain temp wise, do a little
: testing.

Always a good idea.... test a little and get temps with and without heater and same with lights... You will get your best info from testing where you are and with what you are working with.

: How much faster does fast hardner work? Are we still talking 24 hours for a
: cure session? I also understand more chance with amine blush, but that it
: can be washed off?

Depending on the inside temps. maybe less. Setting time will be more of a factor with the fast hardeners... You may have less working time if it's real warm. ?? Another thing you should probably test. When you get your epoxy, mix some up.... maybe about two or three teaspoons and spread half on a piece of plywood and leave the rest in the cup and check to see what your working time will be. Spread out.. it stays cooler and sets slower.

Blush can be washed off with soapy water and green scouring pad, or maybe just the scouring pad and warm water...
