mosca will get to yall sooner or later.
but frankly if i had them and the time i'd run them anyway. avg, the flower time from what you already know about OTM & BK. can't be that much different imho. besides you're gonna use a trich scope to harvest anyway right.
yield should go up some over normal BK anyway you cut it. a 1/2 & 1/2 pheno would do that and a otm dom pheno will do that to imho.
so far as feeding that would be easy. start with 1/2 strenth nutes as usual and let the plants tell you if they want more from there. not rocket science imho.
i'm hoping this post will light a fire under yalls ass lol. and please share the veg/bud porn in a thread with us. pretty please!
