So been a few weeks since I first posted and the stretch has been insane 1-2" a day. I have ran out of vertical space and been pulling them to the sides with yoyos but will probably have to go across the room if they do not slow down. Some of the girls do not mind the high light levels when close to the leds but some of the others have been less then happy with it. I have moved them around since but the ones that were closest to the door are clearly behind the rest which is either do to the green light or possibly light leaks reflecting off floor. I have used the same green led floods for years and have never had an issue with them but in this setup they are far closer then I have had them in past setups. There are three plants effected this way and I expect them to finish weeks after the others.
My lights were originally mounted on racket hangers on the shelf but I have had to since move the lights up on top of the shelf with spacer blocks. I did this two days ago and was worried that they may build up to much heat being a couple inches from the ceiling but so far it has been ok. Currently have 6x QB288 V1 running at 150w each and then have 4x QB120 @ 50w each. I was hoping to run the 120s a little higher but voltage drop is limiting what the constant current driver can put out. My veg 132s have their drivers mounted on the back side right next to panels which allow for much shorter lines and I will do the same with the 120s after I am finished. My other panels are running in parallel at twice the voltage so are less effected by the line length from power supply to panel. I will probably be adding some of my older burple style panels and maybe possibly a couple veg 288s to balance out the light in the room soon.
Feeding has been minimal and I have actually backed it off a bit in the last week or so. I ran 3.5g per gallon on the bloom and they were not happy with it so will back off to 2.5g per gallon and at least 2 watering between feeding. My nitrogen is coming from some dry fertilizer I top dressed a week before flipping and has held out longer then expected but I am starting to see it finally running out they are darker green then they should be at this point. When I feed they get about 1/2 a gallon of solution each and when watering they get a little over a gallon. At the time of potting them up I only had the soil mix which I use for peppers which has little aggregate and is fairly dense for bottom watering. So I have to be careful about over watering but with this finishing going well into summer the extra heat may make that work out to my advantage.
@IndaGC, Wow that long F me yeah I'll probably go with a different Sativa wow that is a very long time I was thinking more like an ak47 sativa lol I know there are many sets of variable's that come into play during stretch i myself have a hard time judging them but its one of the things im working on :)
@TheUk420Show, 100% Sativa. Yields are lower then most strains although I had some 2016 batch seeds that produced heavier buds but it was grown in a greenhouse. It grows pretty much the close to Chocolate Thia maybe 4 weeks longer or so. Genetics matter big time but there is factors witch you can control stretch to a degree such as high night low day temps, letting it be almost root bound going into flower, increasing blue light in flower and running them on a screen. I should have ran a screen at 6' in the room and it would have been easier, now I will have to pull them over at an angle to keep them from getting to close to the lights. I think a lot of people call them "hard" because of the time investment into them and there is a greater window for something going wrong. Another issue is they have very long flexible branches which will fall over pretty easy, under sunlight it is not as big of an issue though. I first grew this about a year after getting my medical and ended up having to zig zag the branches through the tent luckily I was running PLL florescent bulbs which allowed for them to almost touch the lights. The high on it is worth all the effort, super clean, long lasting and you will remember the first time you smoked it. If you do grow it and only have a single flower room I high recommend making sure you have a stash that will last you 8-9 months before setting out.
@IndaGC, Yeah I meant more the genetic in particular is apparently a very tricky one to get a good yield from and to grow overall. Not my words. She's a full Sativa isn't she ? How much yield do you get from this pheno ? does it compare to any other strains you have done in the past or is it one of them that its not really about the genetic its how you grow it ? I'm really interested at giving it a shot one day I just think I may not be experienced enough to cultivate it yet.
