I peeked at those just sprouting seeds this morning and tiny little seed leaves were open. These are Salvia seedlings, so strictly speaking, they don't belong in this forum But I did manage to get the basics set up in my main Grow Light Area (seed starting/growing area lit with lights) to move out the salad mix box (8 seeds each: lettuce, radish, beets, rainbow chard, miner's lettuce) Checked on them after one hour and, in the 28Ã‚ÂºF garage, the GLA soil surface temp was 50Ã‚ÂºF. So it's just about right. (I'll check before lights out to make sure they're not going to freeze.)So I have some seeds waiting to sprout/just starting to germinate on a seedling heating mat in lower 60's room (heating mat supplies +10Ã‚Âº) but no lights, and some cool weather seedlings that sprouted already (from which I TOOK that heating mat after germination) but which are under lights. I'll be transferring the germinated seedlings under the lights out to the main Grow Light Area in the cold (we're talking upper 20's to 30's) no-window garage tomorrow after I set the area up with extra heat (40's to 50's) and new tubes of light, moving the just barely sprouted seedlings under the light, and setting out another tray of seeds on the heating mat.
After that, I was able to move the wee Salvias to the lighted indoor seedling area.
Tomorrow, I'll start the 2 kinds of cotton seeds and Broccoflower, Brussels Sprouts, Kale, 3x cabbage, and 4x Lettuce. Once these sprout, they'll also go out in the GLA.
The key to my transplant production shuffle is going to be moving the cold weather crops OUTSIDE just as the warm weathers germinate and need to go in the main GLA area (which will need to be modified to generate more heat, but by then, the garage temperature *should* remain up in the 30's and above. I want to set up some low tunnels, but, at the moment, the garden beds are all still covered in 20+ inches of snow!
