I knew you’d MacGyver something that would work just fine. ;)
I’ve sold a ton of those little ‘grow houses’ through the years. I used one on my kitchen porch for starting cold-hardy things and hardening off others before we built the greenhouse. They’re handy!
Stopped by Menard’s and grabbed some 1020 trays and square jiffy pots that fit to be the equivalent of 50 cell trays. Potting up from 72 cell trays was a pain. I’d rather go straight into the ground. Grabbed one humidity dome, a bag of Burpee organic seed starting mix and some 20-20-20 fertilizer.
As soon as I find my missing 1020 tray, 72 cell tray and dome, I’ll have the full 8 tray setups. If I never find it, I’ll roll with seven.
Still need more heat mats. I’m thinking with four shelves of two trays each, I can probably get by with a total of four mats, two for each bottom shelf or one for shelf 1 and one for shelf 3 and close the tent up at night if it’s cold.
For that matter, I could probably get by with just the two for germination purposes and do that on the bottom shelf. Close it on cold nights. Heat rises.
Got cheapo trays. I was going to order from the web some heavy duty trays and jiffy pellets that come in sheets for 1020 trays ... but there’s so many little things I want but there’s a few big things I need and a buddy to pay back so for one more year, I’m going as cheap as I can for seed/plant starting.
Couple more months and I’ll be caught up and have more spending money.
