I don't grow anything under 12/12 that's why I only buy auto's ...so I don't have to worry about 12/12 ...the one exception is the mataro blue I'm growing now... kannabia sent me some photo's by mistake I grew one thinking it was an auto I just now switched it to 12/12 looks like she'll be a monster too ...she's been in veg mode since mid march!... it's taking way too long but she's alive and well so I have to keep her going...I writing kannabia now seeing if there's a way they can write me back that thai is an 'auto' once and for all!... seems like there are a few folks that somehow want to disagree even when I post the package and the attitude listing ..what'z up with that ...if I told you all my grow secrets on how to grow big fat ass plants like 'thai' I'd probably get a line of people saying you can't do that...but that's what keeps it fun! 'bud luck' to ya!
I'm going try and see if I can get kannabia to join the forum then everyone can ask them the specifics about light- time and if it's really an auto I hate having to answer all those types of questions.... again all I know is I put her under the light with my green thumbs and let em go! and I usually get a pretty good haul
