    So as most of you know I'm growing various strains by various banks to Gage genetics. Ck, mg, tnls, and many more. A few of my ladies are 3-4 weeks old and are showing some pistils, all strains are at supposed to be a minimum of 100cm. 3 weeks and they are very bushy with lots of outward growth day to day. I raised my 4 qb96 v2s to hopefully increase my chances of vertical growth. Do autos have a vertical growth spurt after this point? Think I have the QBs too close to canopy and it encouraged growth outwards. Some say they explode with growth as soon as they show signs of flowering and others are negative nancies saying that they only get this tall at this point and I'd be lucky to crop a half zip. Anyone with any experience with Autoflowers?

    Definitely a problem I’ve had with the QB’s they’re just intense as hell. I had to turn mine all the way down during veg to get any vertical growth what so ever.

    Well I brought them up to 30" above and dimmed them way down to where my 3 in 1 soil meter is reading that lights are 4 out of 10 in the green. Hoping I gain a foot or so vertical height or I won't have much of a stash.

    Most autos will do what their genetics allow and gonna do their own thing,,as soon as the rudullious(not correct spelling) lol ,,but its like programming a robot its gonna do what its programmed to do really not to much u can do most autos get much bigger n taller now than they did when they first became popular

    Well I'm going into week 4 and they almost fill their 5 gal circumference with foliage but only 6-8 inches tall, was just wondering if they have any growth spurt once pistils are seen? Definitely not close to 100 cm on any of them lol

    They got a little burnt I think from overpowered QBs lol, not too bad tho...1/4 maybe less on each tip or so, hope I didn't hurt em.... extremely powerful little fucking lights to veg on I guess. De 1000w didn't even burn at 20" but these did lol
