My last post got cut off. I use wood for heat in my house..pellet is key for greenhouse. The new ones have thermostats and auto ignition. Let's you go fully automated. It will turn on at night and turn off in the am on its own. On overcast winter days, when solar gain isn't enough to get it up to 70f+, it will run for a few minutes and shut off. When humidity is to high outside (raining out), my controller will heat and vent at the same time in cycles, dropping my humidity better then any dehumidifier. I can explain more about how this works of any of you are interested.
Just wanted to show you one more thing about foundations before I move on. If you hit rock when you are pounding your ground stakes in, stop. If you keep beating it down it will just go in crooked. Just mount the receiver to the box and put another stake in for support as close as you can without hitting rock.
I'm using 1x2 strips all around to mount my wiggle wire to. Using these bent around my end walls is an experiment. They are completely unnecessary if using wiggle wire channel.
O and just a fun picture. I picked up dirt for my starts. I veg my seeds and clones in 20 gallon bags of dirt. Cut the top off the bag and drop a seed start/clone in. Then I cut the bag and drop into it's final spot when it's time to plant. 148 3cft bags.
