Alright cool. Mine are gna be about 15in tall too by the time I get my cmh bulb. I have enough room to grow them upto 6 feet tall but I know they wont be gettin much light penetration in the lower parts of the plant so wanna keep em under 5 feet. I have 3 types of og and 2 types of bubba. Im gonna keep. One of the mothers I got for free as an actual mother and I took a cut of each strain so that when I see which I like the most ill just stick with 3 main strains. Most likely its gna be the sfv og, pre98 and madman og or platinum bubba
