if you like head lettuce, which usually has a milder flavor, then starting the seeds indoors (or buying from lowes) is the way to go. that way you can space the plants to allow the heads to form better.
we kinda like those earthy and green flavors, so we plant seed mixes that are stronger flavored plants. but at a certain point of heat and sun, almost all greens get bitter. too bitter to eat.
what kind of peppers did you grow? i'd be interested in a swap. vb has a garden too, so we may be able to do a three way with veggies.
umm, you know what i mean.
