Ak tomato'in
Michael, temps are about 60 outside, a few degrees warmer in the GH.
I started my seeds indoors under a 400 watt high pressure sodium from Feb. 15 to April 2nd. I intially heated my water, which is in a insulated 300 gallon tank, with a wood furnace that blows hot air through duct work, so I branched duct-work off of the main stem and went under the tank with the hot air. Not only saved a fortune in natural gas heat but I got nice 70 degree water every night from 42 out of the well.
The hot weather we had was much more of a challenge, I had plants drying out too much, it was over 90 in the greenhouse for weeks. I tried watering more often with less amounts, then came some fruit cracks, instead of BER, a small percentage damaged, but mood dampening indeed. I am buying a shade cloth in case that event ever returns to AK.
I use Flora Nova, in pro-mix, some pots has compost mixed in to compare results, as well as taste.
