Are my seedlings doing ok?
I'm worried they might have a bit too much stem. As you can see, they've just acquired their first sets of true leaves and they're about 1.5-2" tall.
(my daughter has trouble holding the ruler straight, lol)
All my seedlings look about identical to this. I actually have a bunch of questions:
1) Are they too leggy? I am using a 48" shop light with 2 40W T12 bulbs in it, and I'm trying to keep the light less than an inch from the seedlings. They are currently getting 16 hours of light per day.
2) Should I put some more dirt in there? Unfortunately, I made the (I think) mistake of using potting soil instead of seed-starting mix. Luckily, they seemed to have germinated without any health problems as of yet (knock on wood). I did leave some extra room for more dirt if need be. So, if they are too leggy, maybe I can add some more dirt instead of repotting them?
3) These are 3" peat pots. Do you think I'll be able to get away with growing the tomato plants in these until it's time to go outside? Or will I need to transplant them into something bigger before then? I have no problem transplanting them, but I'm currently using all the space I have available under the shop light so if I have to repot them in bigger containers, some of the plants will probably have to die.
4) As you can see, I planted two per pot. When should I thin them?
