I am new to seed starting, so forgive me if these are oft repeated questions.
We had some problems starting lettuce plants a couple of weeks ago, and we're trying again. They germinated, but then died a few days later.
We're placing seeds in small starter pods, keeping the starter mix moist and warm with a heat pad, and placing them under a grow light.
1) Once the seeds germinate and pop out of the start mix, should we take them off the heating pad?
2) If yes to # 1, how warm should the air temp be while the seedlings are growing.
3) How long should it take for true leaves to appear?
4) Should we wait for true leaves to appear before we add some "liquid fish" fertilizer?
I will appreciate any advice you can offer. THank you in advance!!
