BOOM! My 2019 Growing Season is Officially Underway
My 1020 tray setup consists of 5 layers (from bottom to top):
- lattice tray (for support while handling)
- 1020 tray without holes (so I can just dump water into the next tray up)
- 1020 tray with holes (so excess water drains down)
- 48-cell inserts (for the actual seedling starting mix)
- a clear 1020 dome (used for the 1st week or so for humidity control)
Add to that a seedling heat mat. I have two of them. As I transfer seedlings into the cells, the first two trays get a heat mat. The next trays evict the earlier trays from the heat. Since seed transfer often spreads over a couple of weeks, it all works out well.
Another layer that is sometimes required is a small sheet of Agribon AG-15 on top, to screen the direct sun that comes into my wire shelves on the back porch. I've made up Popsicle sticks as labels (1 for every 4 cell pack) with the variety named on both sides. The Agribon is supported either by the clear dome, or by the Popsicle sticks that protrude from the cells.
The cell inserts are virgin. To sanitize the trays, I hose them off, then spray any exposed surfaces with cheap "bathroom" spray from Walmart. It's basically bleach plus a bit of detergent. Then they are well rinsed, and dried.
I can now say that I started my seed in February. Whew! My seedling mix (same as my starting mix) is:
- 2/3 MiracleGro Peat Moss
- 1/6 MiracleGro Perlite
- 1/6 Vermiculite
I mix it up in a 5 gallon bucket. With its lid on, it lives on my porch.
The starting cups are mostly filled with mix, then 1/4 cup of water is added to each. Seed is lightly sprinkled on top, then it is lightly misted with water, to settle the seed. The lids will stay on until they germinate (on a seedling heat mat), then the lids will be left ajar. The relatively deep jars make maintaining the proper moisture easier than with shallow soil. I just look for residual water at the very bottom. When its nearly gone, I add more, by pouring it down the side of the jar. The initial water is usually enough to take the seeds to the point of being transferred to individual cells.
Five of my varieties are showing green in their coffee filter test germination. The Little Yellow is not as convincing yet. But it's early. I'll worry after another week.
