Hey everyone,
I’ve been growing broccolini hydroponically in my Alto vertical garden for about 3 months now, and while the plants look incredibly healthy and leafy, there’s still no sign of flowering or head formation.
I’ve adjusted nutrients to a low-nitrogen mix (about 1 part nitrogen to 3 parts phosphorus and potassium), and everything else in my system such as peppers, tomatoes, bok choy, lettuce, and basil is thriving. The environment is air-conditioned and stable, but I’m starting to wonder if broccolini simply will not trigger flowering indoors without a cool cycle or vernalization cue.
Has anyone else run into this?
• Did your broccolini ever produce heads or just keep growing leaves?
• Did you try chilling the root zone or changing light cycles to get it to bolt?
• Or is this just one of those crops that prefers soil and cooler outdoor temperatures?
Any experiences, tricks, or even failed attempts would be really helpful. I’m trying to figure out if it’s worth keeping these big, beautiful plants growing or starting fresh with a different variety.
Thanks in advance for any insight! 🌱

My broccoli is like that too. No flowers yet. Only baby leafs.
DAT 54.
it’s fall from 20 days ago with 15-27 celcius.
Kratky, perlite, EC 3.0, pH 5.5 from mid 6.o.
100% artificial lights (6000-6500K LEDs) with roughly 200 < umol/s*m^2
I could be wrong, but the plant pictured doesn’t look like broccoli/broccolini. Looks like some kind of mustard maybe.

Thank you. Yes it is a heavy feeder and drinks a ton of water of water. We are at day 76 since sprouting.
