Plants look great, and you have a great head start on the up coming season! I'm in zone 9b according to the :
USDA Plant Hardiness Zone Map
And lately (last 2 winters) the low side of the temps haven't been hitting us. I made the hoop houses 2 seasons ago, and for me they were too hard to control the heat when the sun hit them. Once I retire and have all day here to manage them, I will use them again. My background is growing mainly tomatoes , and others since 1982, that's where I shine. Peppers are a real challenge here. I put maters in March 1st, and they excel, in fact they kick butt. Peppers, are another animal. I should mention I grow in the dirt, not pots, but am migrating to them for reasons I'm about the mention. Here, peppers have to go in around April 1st. Or, they sit there and don't grow (if planted earlier). But....by then the heat is coming on and they look great but don't produce as the super hot weather hits and they don't set. Not like the peeps up North do. They make me look really bad...LOL.
So this season after a dismal spring grow I went with a fall grow, and they're doing OK, still. But I'm hoping I make it happen (large harvest) before a frost.
So back to your head start. That should do you really well. This next season I'm starting this next weekend, it's supposed to rain so I'll plant my seeds. And hopefully have robust plants to get things going in the spring.
One thing, if they don't produce in the spring and you have the want to keep them going through the heat of summer, they will produce as it cools.
Good luck!
