Last might, my daughter and I moved some seedlings around.
The tray from the big aquarium greenhouse is now on the bottom shelf of the mini-greenhouse. The Cup of Moldova tomatoes in particular, were getting so big, they were getting too close to the lights. Plus, they really needed to be off the heat mat.
The bottom three shelves of the mini-greenhouse get direct sunlight in the mornings, so the tray with the tree seeds got moved to the top shelf, which gets no direct sunlight at all. The downside with this set up is that we no longer have a way to provide artificial light, so we’ll have to keep an eye on them, and rotate the trays as needed.
The pots with gourd seeds that did not germinate yet (including the one with just leaf starting to show along the side) got transferred to a new tray and remain on the heat mat. There is still only one Wonderberry sprout, so I took the outer cups off and put them in with the remaining gourd pots. Hopefully, the added warmth will help with those. I also transferred the shallots tray under the lights. There are two tiny sprouts showing!
I’m a bit perplexed over the bulb onions, in the small tank. They all seem to have dried tips. Especially the ones in the larger tray, where one entire spot of seedlings seems to be drying up. In one tray, most of the tips still have their seed cases on them, but the ones that don’t, have the dried tips. I’ve lowered the whole thing, so they’re not as close to the light, though I don’t see how this light could be the problem.
Any onion growers that have experienced this? Last year, we did have the one type that survived to be transplanted, and I don’t remember having issues like this at all, though it was in the other tank. I’m making sure the soil is hydrated, but not too wet, and the light on this tank isn’t as bright as the others, nor does it get as warm as one of the light fixtures on the big tank, so they’re not getting “burned”. We also put a fan on the tank, for air circulation and to help keep the seedlings from getting too leggy. We have just the one little fan, so it gets alternated between the two tanks.
As long as they keep growing, I’m not too worried. Eventually, they’ll be getting hair cuts, anyhow. But if they all start shrivelling away, I’d like to know why! We used all the seeds in the packets in these trays, so it’s not like we can start over, either.
