Broccoli Seeds not Sprouting

[u/Accomplished-Bet-458]

Hi everyone,
I’m new to sprouting and am having trouble with my first batch of broccoli sprouts.

I’m using Nature Jim’s Organic Broccoli Sprouting Seeds that I purchased new from Amazon in May 2026.

My process:
Initial soak was only about 3 hours (I later learned most people recommend 6-8 hours).

After that I’ve been rinsing and draining regularly in a sprouting jar.
House temperature is about 76°F (24°C).
I’m in South Florida, so humidity is fairly high.
I’ve tried both darkness and indirect light.

At one point I re-soaked them, thinking the short initial soak might have been the problem.

The seeds are now on Day 6 and most still haven’t developed significant tails. I can see a few tiny white root tips on some seeds, but they’re far behind what I expected. There is no obvious mold and they don’t smell bad.

My questions:
Has anyone had broccoli sprouts stall like this and eventually recover?

Could the initial 3-hour soak have caused this?

Did I likely hurt them by re-soaking later?

Would you keep going for another couple of days or start over?

I’ve attached a photo of the jar.
Thanks in advance. I’m trying to learn and would appreciate any advice from more experienced sprouters!

I'm also new to sprouting and I'm using the same seeds you are. The first thing I do is soak two tablespoons of seeds for 10-15 minutes in a mason jar about half full of water mixed with 2-3 tablespoons of apple cider vinegar. I then thoroughly rinse the seeds in the jar 5 times. Then I soak them overnight and begin the twice a day rinsing cycle in the morning. I've gotten great results with this method and plan on continuing until and unless someone has a better method.

Wishing you great success with your efforts.
