Yes, these are mainly for the greens. However, I also want to see if it is practical to plant them inside the greenhouse and transplant them next spring. Last autumn, I planted some directly outside, but none survived. I don't know that's because they grew already too much before the frost repeatedly hit, or for other reasons, they were all destroyed after winter.
different varieties of garlic do vary in how much cold they tolerate. the type i grow is a hardneck garlic which doesn't need any protection at all from the cold we get here. i don't even mulch it. some other garlics would fail if treated that ways.
The greenhouse is without heating, so it is more like a cold-frame planting environment. It's an extension of the main building so that the temperature can be a few degrees higher than outside. Another advantage is to avoid too much moisture. Last winter we had so much rain.
as long as the garlic is alive and the soil is not going septic i've had no problem growing garlic here in our mostly clay soils. i do lift the garlic patches up a bit so there isn't any standing water on them, but otherwise they can be soggy for now until next summer and the garlic will do fine. again this can vary by variety as to how tolerant they are of such conditions.
eventually you may find types that you like and will survive outside without much worries.
also i think you might be familiar with green garlic as a vegetable and that is a whole different idea in terms of planting and harvest, but you can sometimes use the same kinds of garlic if you find some you like.
