Building greenhouses by yourself sucks. I usually do them with my one homey but he had some personal shit going on. What we can do together in 2 days, takes me a full week. Got plastic up and ladies in. Got it all ghetto rigged just to get them in.
Devoted 1: For the pellet stove. Installing is pretty simple. Do it like a house kind of. I built a small 2x4 box so I could hook up the wall thimble to it. You just need a regular old pellet vent kit for a house, 2x4s and some osb. I have a solid north end wall so it's easy to mount the box to the endwall. I will do an auto light dep thread building a 20x60 after this one is done. I'll share some pictures today of an auto. ![]() ![]()

Deezle: you can buy fancy greenhouse controlers. They have ports for heat and fans that work off humidity, c02, and temperature. Basically the answer for everything is heating and venting. Do a Google search for "how relative humidity works" and for " dehumidify commercial greenhouse". It will explain better. Humidity is measured in rh. Rh is relative humidity. It's how much moisture is in the air relative to how much moisture the air can hold. The warmer air is, the more moisture it can hold. Let's say it's 40f out and 100%rh. You bring it in the green house and heat it to just 60f and the rh drops to 50%rh.
This is basically the opposite of how compressor dehumidifiers work. They work on dew point. They lower the temperature of the air so it can't hold as much moisture. Moisture condenses into water and runs into the bucket, then they reheat the air. All that is totally unnecessary in a greenhouse. It uses a ton of electricity, and puts off heat anyway. I don't use a fancy greenhouse controller. I just have a seperate fan controller and I have a thermostat for my stoves. If the rh gets to high, it runs the exhaust/intake. The thermostat on the stove kicks on to keep the air the right temperature. I use a regular 25$ bi-metalic thermostat from a hardware store for stove. |
