I didn’t use it outside though like I’ve seen some people do. Maybe that would work in late spring or down south. I set it up in the enclosed porch (we call it the breezeway) in a window facing somewhat south.
The breezeway is partially heated but it gets very cool. However under the flats of seed starts, I put heating pads. I didn’t buy those expensive heat pads they sell in the plant section. Just a couple old ones we had around for sore muscles and backs.
The aluminum loaf tins you see in the photos didn’t seem to work that well for me. I don’t know why, or if it was just a coincidence. I also think the seed starting mix I bought cheap may not be the best. I have since started using a Miracle Gro mix but not in the aluminum so I can’t say if that made a difference. I also had trouble in the small compartmental peat pots so maybe it was the mix or maybe just my brown thumb :(. I am thinking of trying a soil blocker next year. I also have had success with toilet paper tubes (more in a later post). All in all, I may have to buy some starts this year, particularly hot, and maybe sweet, peppers. I am going to transplant some of them today and see if they improve. But they probably should be going out into the garden. *sigh* Late as usual. Once it gets going though, it should do very well.
PS I should point out that I have Kale started in an aluminum tray with that starting mix and it’s doing well. It’s not huge but it is alive and healthy looking. Kale is a tough plant though I think (my first time growing it), but it was worth noting. I think I’ll transplant that today too.
