    Ok, all my seedlings are growing now.

    I had them about a half inch under fluorescent light for a couple of weeks after they sprouted, and now I am moving the light up slowly. Right now it is about 1 1/2- 2 inches over the seedlings. When should I move it up higher and how high?

    Also, I was very careful not to overwater as to not encounter the dreaded damp off. But now that everyone is happy and growing, do I increase my watering? I was waiting until the peat pots were relatively dry and then I'd water from the bottom. Do I continue doing that, or should I water more often? I think the tomatoes are looking a bit shriveled.

    And how high will my seedlings get before I transplant them? Right now at about 3 weeks they are less than 2" tall.

    And what about fertilizer? Can I use something now or should I wait until they are outside?

    Thanks-
    Leah

    It's hard to say about the watering, I do it by sight, but the seedlings can be transplanted when they get their first "true" set of leaves. The first 2 leaves are dicots, or seed leaves, the second pair are the first true leaves. Go ahead and fertilize if you are using something gentle like fish/seaweed food, but wait a bit if you are using something harsher.

    Leaj,

    Your watering regimine sounds fine. Don't let them dry out so much that they turn into peat bricks <g>, but letting the top inch or so of soil go dry is fine. About the lighting. As long as they are under artificial light, keep the lights withing 1-2 inches of the tops of the seedlings, otherwise they'll strech out to reach the light and you will end up with leggy seedlings.

    About transplanting ... Bonnie lass is on the money. Wait until the have their first true set of leaves at least.

    Fertilizer. They probably don't need it, but if you feel the need I wouldn't go with anything stronger than 1/4 strength. Avoid the fish emulsion if the plants are still indoors (stinks like fish) but there are a couple of Kelp/seaweed fertilizers that work pretty well.

    Have fun!

    I press my finger into the soil if none remains when I remove my finger, then it needs water. I would hold off on fertilizer for now. I agree with Niki about the transplanting. Start taking them outside weather permiting in a protected area. Gradually increase sun. I satart with early moring sun and then increase.

    The watering sounds fine - all my little guys are in six-packs at the moment, up from a starter tray. I wait till the soil turns a bit light in color and then water. I also spray mine with plain water once or twice a day, but some folk say that spoils them rotten (just like too many toys for kids, I guess!!)

    I start mine in miracle-gro soil. First set of true leaves gets them bigger pots (more soil, lol!). Third set of true leaves gets them a bit more miracle-gro in the water. Then once they are outside, depending on weather, they get it again at every three to five weeks.
