Jawbreaker(s) not growing

[jason7570]

So I’ve had these for about 3 years now, got them as babies and are still about the size of an eraser. All my other shrooms grow fine except for these. Right now they’re under hydra 26’s around 100 par and low flow. I’ve tried low (45 par) medium and high (225) in the past 3 years and still exactly the same.
Does anyone know how to get these crazy things to grow?

Just our of curiosity, do you direct feed them? I have a Candy Crush, Kryptonite, Frank, Sunkist and neptune. All have grown considerably faster than my JB.

All my shrooms took off when I gave them a little more flow than low flow. So medium flow and about 125-150 par.

Yes, I do feed them reefroids and dose coral amino’s. Thanks for the info, I’ll try and up the flow in the shroom box...

I got mines about a year ago. I place them on floor so far, I got 4 babies. 3 years is a long time for no growth. Are you still getting little babies tho?
