| Hardening the plants off is certainly important, and your seedlings look pretty big already so should do well.
A few things I've picked up about growing seedlings are:
They aren't so bothered about day/night temp changes, which is good because seedlings like abit of extra warmth.
Catt seedlings will want to stay abit more moist, but yours look quite big so will probably be developing bulbs now, so could do alright with abit more dryness, which will be good to help combat fungi.
Try to water with RO water or rainwater as seedlings can be more prone to salt burning, which can cause leaves yellowing.
I would agree with arleneg, to harden the plants off open the lid abit more each week so the plants can acclimatise. The faster they're out of those tanks the better chance they have of growing. |
