newbie with seedlings needs help

nitisMarch 19, 2011

I have four flats of seedlings going under 4 flourescent tubes.

One of my flats is the peat 50 cell sections the others are the 72 cell plastic ones

The ones in the Peat have not done a whole lot since being transplanted into them they have the initial 2 leaves and the buds of more but literally have not changed in 2 weeks and if anything are getting a little yellow. My guess too much water?

I know my light is probably not optimum but should be adequate right? I have good heat as I have the Amish fireplace running right next to them.

Yellow leaves usually means too much water, indeed.
Peat holds a lot of water and doesn't dry well, so overwatering is generally a given.

I'm about to pot by peppers up into 16 oz cups with generic peat-based potting soil... I was wondering, would mixing a large proportion of pumice be good for the seedlings? They are very small right now, only 2 or 3 true leaves each.

Pumice is an excellent additive, although it should be rinsed before using (to remove the fine dust).
Pumice will improve drainage, it will displace excess water volume, and it will provide a durable
open structure allowing air to return to the roots. Also, pumice is abrasive, which encourages root-branching.

If you're unsure, maybe experiment with just a few seedlings.
