Damn, these mothers grow fast once they get out of the ground. I'm having some issues with heat... I've got an exhaust with a fan coming out near the top, but it doesn't seem to do too much. Most of the time I've got to keep it open with a fan blowing inside. I think I'll try to get some soft of smaller fan to hang inside, but then I'm not sure what will happen as far as humidity...

Anyways, learning experience. I think they look good so far. I think there are 11 seeds that haven't done anything at all yet so we'll see how that goes...

Pics from last night, this morning and this evening...

Btw, the white stuff on the hydroton in the 3rd picture... Anyone know what that is... Or rather, if it's bad?

Looks like hard water spots to me.
Salts and minerals in tap water can cause that.

Hmm, interesting. I'm using RO water...

Oh well, I'm sure it's probably not a huge issue, just being careful. I just hope its not some sort of mold.

Well they're doing pretty fine and dandy, no new pics. I'm kind of disappointed with my germ %, but it's my first time so meh. Hoping not too many turn out to be male. Anyone know how soon they might start to sex on 12/12 from seed?

normally about 16-21 days is when you are fully able to tell whether they are male or females using 12/12. I want to say the males develop sooner with the females show sex in between 18-23 days or so. hope this helps. good luck and good work so far

Perfect, thank you!

I've got an interesting development... I was given two clones by a friend because they weren't doing too well with the space he had to give them. So now I've got these new ladies in the corner. There's some yellow spotting on one. Spider mites possibly? Or it is just malnutrition kind of thing?

If it's spider mites what would I do?

Also bottom of the stem looks pretty bad. It's not just yellow, it's blackening. Rot?

Sorry man, not a good idea. 12/12 from seed is plants all the same size, you just brought in two that are going to throw your lighting off. Plus you brought in plants that have been in a different environment and possibly have spider mites?

Oh well live and learn. The stalk looks fine to me.

Good luck.

Hmm, well I did have some extra room as far as the lighting goes, but now you've got me worried. I figure since everything was 12/12 it would almost be perfect, they might not all flower at the same time, but at least I won't be forcing anything into weird light cycles that they wouldn't already be getting.

I got some neem (sp?) oil for the spider might issue...

Shit, now I'm not sure what to do. If they don't stay here, they pretty much are dead and I feel like it would be such a waste to just throw out two females, especially when I was already under my expected germ #.

Shit, haha.
