They should be fine in the Jiffy mix, but remember it has no nutrients, so you'll need to remember to fertilize.

Ah OK- I think from now on I'll use normal potting soil.

Is a diluted dosage of all-purpose Miracle grow acceptable?

Thanks again-

Boy, I dunno; I'm sure anything, diluted enough, would work. I personally like to use a diluted fish/seaweed emulsion (well, I don't like the SMELL, but I like the product). It may just be in my head, but I like that it's organic and I feel like I have less of a chance of burning the seedlings since it's not made of chemicals. But that's just my uneducated opinion. Most things I don't fertilize too much anyway, since I can hardly keep up with potting up the seedlings that are growing like crazy already. So I mostly just use it on the slow-growing plants and the heavy feeders. I'd hesitate to use Miracle Grow, and find something geared especially for young seedlings or transplants instead. Under fertilizing is better than over fertilizing.

OK thanks for the help. I like the idea of using something organic better than chemicals as well.

Where could I find a fish/seaweed type fertilizer?

Wait until they get a bit older, then use some Dyna Gro Foliage Pro 9-3-6. IMO, one of the best fertilizers available for any veggie plants. Start with a 1/2 strength dose at 5-6 weeks of age, then gradually work up to a full dose when about to place outdoors.
