You'll find many more details about all this in the FAQ here on Growing from Seed and on the Growing from Seed forum. But basically as soon as they germinate you remove the domes - most don't even use them - and take them off any heat mats used. Leaving the domes in place and on heat increases fungal disease issues and generates leggy seedlings with weak stems and poor circulation systems.

A few of yours are already getting leggy and may begin to lay over so dome off ASAP and increase the light as much as possible and as close as possible. When you transplant them to individual pots be sure bury all that stem up to just below the cotyledons.

Thank you so much digdirt2! That was very helpful. :)

At first glance they do seem somewhat tall, but depends on variety as well.

Just keep night temps low-ish and decent light during the day and they will turn out great.

Ok thanks so much!
