The very good news is that my tomato seedling have finally started to show true leaves. You can read about my problems here. Transplanting, less water, and better light seem to be the solution. Our new lights seem to be really making a difference as the seedlings inside have done better than the ones outside. I've also be giving the ones inside as much light as I can, just shutting them off when I go to bed, and then the timer comes back on at 4 in the morning.
So here is the progress. Last week's photo is on the left, this weeks on the right.
The set that has been inside under the grow lights:
The set that has been outside in the cold frame:
I guess since the seedlings are doing better under the lights, I should bring in the set from the cold frame. Since almost all my seeds sprouted both seeds I planted and I only wanted one of most varieties, I may have enough healthy seedlings to be able to give some away!
