Thanks for the tag @Myfriendis410 looks like he’s not into the autopots just yet.
@PistilPete welcome to the forums and thus the community! You have a neat looking little germination thing there “click and grow 3” has a tiny little 8w light, the advertising looks good but that light is unfortunately very weak and cannabis is the most light hungry plant your going to find…although I don’t know how bamboo stacks up against cannabis to be honest…
Looks like some sort of rapid rooter hydro starter @dbrn32 knows the real name of them.
Anyways plants are young and I would soak another seed now as I’m sure the middle one just isn’t worth your hassle for the next X amount of months.
They are looking a little more leggy than I prefer and that has to do with the lighting so why not put your HLG hanging over top?
Also do you have a fan blowing a light breeze on them? That should make them toughen up.
I’m following along so keep at it, just soak another seed, hang your HLG above it and give them a light breeze.
