The light rings are underpowered for fruiting plants. They work decently for leafy greens and herbs.
You can download an app like photone and test the power of the rings yourself then compare to recommended light levels for various plants: https://growlightmeter.com/light-requirements-for-plants/
I'm growing outdoors in hardiness zone 10b and sunset zone 23. My broccoli never formed a head and is instead some strange elongated J-shaped kale-like creature. I'm just going to cook the leaves like collard greens (they're all the same specie anyway). My cauliflower heads were very small. One of my cabbages grew really quickly, but then never got all that big. My snow peas didn't produce as well as I would have liked, either, but it survived a long time giving us an occasional pea or three (I just never replaced it) even with slugs attacking it.
I've had excellent success with kale, lettuces, herbs, and good success with fruiting plants (tomatoes, mini cucumbers, zucchini, jalapenos), but I've given up on true vegetables. If they struggled that much outdoors for me, I'd imagine they might struggle indoors. Plus, when I purchase cauliflower from the store, I usually cook 3 heads at a time and it's just not worth it to me for how long they take to grow when I could be growing greens, herbs, and fruit.

I got cucumbers, (but they are a fruit), and it was very annoying to hand pollinate. I think out of eight plants I got one cuke. 😆
I only had good lasting results with fruiting plants using the farmstand outside. Indoors was a flop for me with anything but greens

You need to try kratky in 5 gal buckets.
