Longtime readers of this blog may recall my unfortunate run-in with a rat in my potting shed a couple of years ago. Ultimately, it was Rat: 1, Me: 0. The damn critter dug up and ate all my tender seedlings under the grow lights. I tried protecting what was left with duct-taped plastic covers, but the sauna that created was too much for them.
Until I can varmint-proof my potting shed (and I’m working on that!), I have had to move my seedling production center indoors. And this year, so far, so good, though I realized a little too late that the flats were too far away from the light, so my seedlings are a little leggy, but they will be ok. Here is my set-up.
I outfitted an old plastic parson’s bench that was in my attic (thank you, grandparents!) with heating mats and grow lights. Each flat goes on a mat, under a light. The flats stay covered with the clear plastic lids and the lights stay off and the mats on all the time until we achieve sproutage, at which point the covers come off and the lights and mats go onto a timer. On for 12 hours, off for 12 hours.
At that point, I also set up a small fan to blow a gentle breeze onto the seedlings. Air circulation helps them become hardy. No hothouse vegetables tolerated in my rough-and-tumble garden!
As the second set of leaves appears on the seedlings, I move them to the garden window in my kitchen, where they receive direct sunlight. An open window on nice days encourages them to get more comfortable with outdoor environments. And I constantly check the soil for moisture—too much leads to dampening off; too little turns them into microscopic twigs.
And as they mature, I move them into my Growcamp, my little greenhouse/covered garden. There they will harden off—that means they will gradually become accustomed to outdoor life—and hang out until all danger of frost has passed and they can go into the ground.
Here’s what’s in my flats this year, by the way:
- Three kinds of tomatoes
- Two kinds of sweet peppers
- Two kinds of hot peppers
- Three kinds of basil
- Two kinds of marigolds
- Two kinds of zinnias
- Pingtung Eggplant
