Haven't written here in a while, so I thought I would do an update....
I "lost" my Douglas, Balsam and Fraser fir seeds! I could have sworn I put them in my seed box, but they are not there! I ripped this house apart looking for them to no avail. They were in such small envelopes, the only thing I can think is they got mixed up with something and got thrown out. Looks like I have to order more.
I took advantage of some of the cooler days to finally finish putting the slate floor in. I decided not to put slate in the last 4 x 8 feet of the greenhouse. We are going to make a bin in the last section and use it to help heat the greenhouse next winter with an indoor compost pile. I have been watching YouTube Videos of people who have done this. It won't be enough to heat the greenhouse all the way to what I need, but it will help. Here's a video on it.
This Curious Gardener Series is good.
There are 16 YouTube Videos in the series.
Here's another one that is interesting. This guy composts outside and has a space cut in the wall of the greenhouse that let's the heat in.
In addition, I want to weather strip between the panels and frames to stop any heat that may be escaping and prevent cold air infiltration. I found a company that sells weather stripping in bulk...much cheaper than buying it in Home Depot, Lowes or on Amazon. (

Most likely, I will insulate the north and east walls as well with reflective insulation...haven't made up my mind about hardboard insulation or foil coated bubble wrap. I need to do a little more research on the matter. I also read a very interesting thread in another forum of folks who use solar pool covers for greenhouse insulation. It is heavy mil and supposedly will last for years...and, not too expensive.
A little late, but I finally got some seeds planted in the greenhouse yesterday...10 cherry tomatoes, 10 San Marzano Tomatoes, 10 Beefsteak Tomatoes, 10 Black Beauty Egg Pants, 10 California Sweet Peppers, 20 Bantam Sweet Corn. Still have more to get planted in addition to starting my flowers.
