Hey All,

VERY happy to report that my second attempt is going fantastically better than grow 1 in my other post.

However, I was just away for a 5 days with the plant on automatic drip irrigation to keep it watered while I was gone. I came back to nearly 8" in new height. It's very close to the light now. I'm seeing some say to reduce the light to ~50% strength, some say to try to bend it (I'm a little nervous to do that), and some say to top it again.

Questions:
  1. What's your advice on managing the height of this plant for this go-around given the stage and not fully customizable environment (i.e. light height)? Not sure if it's done stretching.​
  2. Dropping light strength has me concerned about bud development - valid concern?​
Additional context:
  • I am planning a significant defoliation to clean up the base later this week to coincide with my feed schedule.​
  • Have already taken notes on better LST implementation and canopy management for next time.​
Grow info:
  • Medium: Fox Farms soil​
  • Liquid Nutrients: Fox Farms Grow Big, Big Bloom, and Tiger Bloom (and some Ph Down on occasion when required)​
  • Seed Type: Auto​
  • Strain: Sour Diesel from ILGM​
  • Tent: Vivosun Growbox​
Growth Stage:
  • Week 2 of Flower​
Appreciate any and all insight and advice!

Question, do you have any more room to move the light up? I would read up on High stress training (HST). Basically you go down about 8-10 inches from the top of the plant, wrap a cloth or something soft around the stem,, then you take a pair of pliers and squeeze until until you crush the stem and it flops over. Be careful not the tear the vascular tissue on the outside of the stem! If need be you can support the bud at a 90 degree angle with string. Reducing the light intensity a lot will affect yield.

Thanks very much. Unfortunately, I'm limited in terms of light height adjustment in this growbox. It's an all-in-one, light is where it is, type of situation. There is an empty water reservoir in the bottom that I will remove to gain another couple inches of headroom, but it will still be pretty close to the light. Definitely looking forward to upgrading to a more adjustable set up in the future. HST is something I'm learning about, but given my novice status here, I'd be worried about accidentally ruining the primary colas (but I suppose the light may ruin them as well...)

The light will eventually fry the buds. Do a test on one of the tall branches, it’s really not that difficult. You’re trying to crush the xylem (the woody interior of the stem), without tearing the phloem (the vascular tissue on the outside of the xylem). You’ll be amazed by the resiliency of the plant.

Looks like it’s either Super Croppin’ or Toppin’ to me. This is how I would approach your situation:

It would suck to lose the tops of your colas in a couple of places but you don’t have room. If you’re comfortable, watch a video or two and do some reading on Super Cropping.

If you don’t do that, your option is to top them. If you screw up the branch bending it, you have to essentially top them by cutting the branch off at a node lower than the damage.

I’d take the gamble on bending the branches because like I said, if you mess up, you get the same results as shearing off part of your branch. If it works, all is saved and you have the space you need for a successful crop.

Supercrop them. Use twist ties or soft wire to hold them in place.

Or maybe make some holes around rim of pot and tie down some branches to open up away from center.

I would also cleanup the lower third of the plant.

Best get to folding some of those tops over. Pick a spot where you want to flop the top and start crushing the stem with your thumb and a couple of fingers. You will feel it start breaking down, work about a 3" area with the most crush at the point where you want it to flop and it will come over. To bad she is in flower, but will recover and keep going being a sativa dominant fufu hybrid and showing sativa like she is. She could get much taller and can have a very long flower period. So there is time to recover if the crazy sativa gal doesn't lose her hormonal mind. Good Luck!

Supercropping is the best option.

I have topped plants at about that stage. It ended well, but most growers don't recommend it. I only did it once out of curiosity.
 
#10
I done it several times when i was growing big outdoor plants and needed to use my greenhouse to finish them off. Take you time when squeezing the branch, my colas on those supercropped came out just fine.

Thanks everyone! I started noticing some spots on the top leaves - presumably light/heat damage? (see pic).

Gave it a clean up on the bottom and did my first attempt at a super crop. Was also able to remove an unneeded water basin at the bottom to get a little more headroom. Here are the results - note that we're back below over height line.

I can't get that low trellis off without causing some unnecessary damage so it stays for now and will be implemented more effectively next time.

I’d bend her, you don’t need to supercrop, I’d just get a Few strings and bend he down tie down to the base or pot edge, she’ll turn back up to the light within a day

Edit just saw the herm comment that sucks, was it a full herm or just a few balls at the bottom?

it looks like you have a net but you are not using it.soo maybe try pulling the braches or doing a supper crop and then again using the net to hold the branches down.
second option is to raise co2 a lot and maybe that will fight the high light intensity but maybe not....

Thanks for the advice. Looks like it went full-send this time, unfortunately.

Thanks, yeah, the net will definitely be implemented smarter next go-around.
