I started my hot & sweet pepper seeds March 16th. With heat, I got germination within a week. But my plants are still very small - some with 2nd set of true leaves, some with first. I have transplanted & buried stems up to cotyledons about 2 weeks ago, but they are only about 1" to 2" tall plants. Does this seem normal? Is there any way to encourage growth? I will be planting out 1st wk of June if weather warms up. Thanks!
