hello m8
ok I am going to be honest with you as I am growing the same strain at about the same date under leds please take it as it is meant
I think they are to crowded and the bud formation seems a little behind for the stage they are at least compared to mine which I am growing 1 per square foot
I think from what you are saying I would raise the lights a little to give a better even coverage over the whole table I am keeping mine at around 20 " and 250 watts (actual draw) seems to cover about 6 sq feet pretty evenly as far as I can tell
I dont think this strain gives you some nice fat colas rather it seem to be heading toward a lot of smaller bud sites but it does seem to cover a area quite well..... we will see and yes like yourself Im finding this one very slow and I think I am looking at 12 to 13 weeks rarther than the 8 stated
I am also trying out some MI5 and they are ten days behind yet I am seeing some huge colas on about 50% of the plants unfortunately the other 50% are all over the place in phenos not something I would grow on a hydroponic tray
as you have seen the problems you face with plants of different height on one tray
however I am seeing the cc as very uniform when they have even light coverage from start to finish
I think you are doing great as this is your first time and you are spotting and asking the correct pertinent questions which are very relevant
this is exactly the traits you need to be good at your game
keep up the good work
I was interested in hearing the issues you have with water temps maybe a bigger tank would help
when growing with 4 x 600w hid lights covering 4sq M I was using a 200L res tank and never had this as a issue although I kept the tanks away from direct light
another thing I have noticed was The cc seemed to like a change to 18/6 whether this was a coincidence or not I'm not certain ?

Thanks for the feedback LHP, truly appreciate legit people that aren't affraid to tell me how it is just to help me out. This strain is def too bushy in my opinion for an aeroponic setup. The sound of MI5 keeps ringing in the back of my head for my next grow.
I'm out of country at the moment, again. (not complaining, I at least have a job and get to travel) But I passed the info on to the roommate to:
*Have the lights raised, which they are now at their highest point with these light hangers that came with the GLP LED.
*Use frozen V8 bottles in the res during light cycle and letting them refreeze during lights out (since the drop in room temps already drops res temps) Also, I invested in a timer to run the res 2 min on/3 min off, for some reason though, I must of spaced, it was still in its packaging on my work bench. That was installed a few days ago. I am being told res temps are down to 70-74.
*Trim up dead/useless leaves
*Change light cycle from 19/5 to 18/6
"pertinent questions which are very relevant this is exactly the traits you need to be good at your game keep up the good work"
I smiled, thanks, I needed that.
Will be updating you guys next year after I get back in to the country.
lol its hard to make the right choices It would be brilliant to see the slightly shorter pheno which has basically one big fat cola this would be fantastic for your aero table lol it makes me dribble thinking about it.... 36 of them over 2m2 I don't think you'd be able to get your finger through the buds
