Onion Flats Under Lights
Here are three flats of onions I planted on February 8th, 9 days ago. Most of the nearly 1,600 seeds are sprouting nicely in flats in the basement. The flats are on a heat mat and lit with various LED grow lights we have accumulated over the last few years.
The onions are growing in a commercial potting soil. I used to make my own potting soils, but I’ve found the commercial mixes to be much more reliable in giving me good strong root growth, and they are certainly a lot easier to work with. Mostly, I’ve been using Jiffy Mix. Jiffy now offers organic mixes and they sell it in large bags, which I like, since I go through a lot.
Copra Onion Seedlings
These seedlings are Copra onions, a very reliable commercial yellow hybrid storage onion that I’ve grown many times. Also planted is Red Bull, a red storage hybrid, new for us. That’s it for the hybrids, the rest of the crop includes, Borretta Cipollini, an old time heirloom flat Italian onion that we’ve only grown once before, and Rossa Lunga di Tropea, a torpedo shaped red Italian heirloom that we have not previously grown.
Finally, we have just over 300 Lincoln leeks seedlings. Lincoln is an old American heirloom that normally does well, although I had a leek crop failure last year. I know my mistake and I hope to have a good leek harvest by replanting my leeks to another outside bed for some growth before I plant them deeply in their final home.
I’ll start fertilizing the flats, soon, and transfer them upstairs to a south facing window to free up the heat mats for tomatoes and other crops that also need the heat to get started.
