Tips on how to increase stacking?

I see a lot of people here producing buds that look like they are a foot long. My most recent grow had some stretching where buds didnt fill in the gaps. Im assuming this is from me raising the light.

What do you guys do? Whats your process when flipping? How do i increase stacking so i can produce some nice buds like you guys lol?

65% is the highest i ran my light during flower and i have it about 2-3 ft from canopy once stretch stopped.

What kind of light are you using? That seems pretty high especially run below 100%. I flower in a 4x4 under a HLG RSpec at 490 watts or so, and that’s a hot centered quad QB light, I keep that about 12-18” off the top of the canopy. It seems like bar light users are usually at somewhere between 6-12”

I run 750 watts 18 inches from canopy once the stretch stops. I’m using an HLG scorpion rspec far red with a uv bar.
I’d say your light isnt turned up enough and it’s too high possibly.

Mars hydro ts3000. 4x4 tent.

I made a previous post about light size and got a lot of useful info.
I decided to crank my light up to 75% after reading about a lot of you guys running on 100% 12-18in from light and my buds began to foxtail… Temps were gettin pretty high with the light at 75%. Thinking about running the ballasts outside of the tent

How high were the temps?

Most of that is in the genetics. Case in point:


The one on the left was vegged longer, but IMO the one on the right has the longer colas, just nicer overall flowers.

So yeah, genetics first & foremost. Light intensity and proper nutrition will help you unlock what the genetics are capable of.

crush the stems as the internode’s stretch out and it’ll keep them shorter = better stacked cola’s.

Thats what im thinking. Next round i plan on running the light at a strict 18in off canopy. Raising as it stretches but never going past 18in.

What % you guys running during veg? How far off the canopy do you keep it during veg?

What % do you guys start flip with? How often do you bump it up to get to the 100% or as high as my set up can handle without extreme temps.

What do you mean? Crush the stem on the new growth as it grows up?

I run a seperate veg and flower tent. In veg I have a 3x3 with a single Diablo board running at ~150 watts.

82 is right about the top of the range I like to be at. Great growth imo.

Yep. As the internode spacing gets over an inch long, I take my thumb and index finger and squeeze that stem section slowly and gently until i feel the stem buckle. You don’t wanna just smash it, but yeah. A couple days later you may need to do it again. If the internode stem length is 2 inches or longer, i’ll crush it in two spots. This will cause the plant to focus growth on other branches while it repairs that one and grows more on top and it keeps the internode spacing shorter because of the damage and repair. Can flower plants at 16 inches tall that normally stretch 4x and keep them under 3ft tall with stacked cola’s and no loss of yield.

Look into super cropping, works really well.

So for future reference, i should run my light 18in above canopy, following the 18in gap thru stretch. With my light running as high as i can keep it without overheat issues?

Look at the manufacturer specs, and/or get a light meter.

The plant that made me make this post was topped and super cropped. Another member who grew the same strain has some really nice colas compared to me. I know its user error just trying to figure out what i did wrong im thinking it had to be the light. Plant grew out amazing but then the stack job sucked cause of something i did

During stretch, the plants generally dgaf what your light is, where its at, or how strong it is. Only in veg and after stretch do they really care about it. If you have an iphone you can get an app called Photone that will give you an idea of the PPFD your light is putting off. I’d generally try and target around 2-300 for veg. 500-700 for stretch and early flower. 800ish or more if you have co2 supplementation for mid flower. and then maybe back to 750ish for late flower.

Knowing what the lights put off, even just an idea, will let you run the lights where they need to be to maintain ppfd/rh/temp. I don’t ever run my lights that high off the canopy except in veg. In flower they’re generally a foot off the top.

It could also be expected variation from seed if you weren’t running clones in the same type of environment.

Happy to finally disagree with you on something, it’s been a while ^^

To produce decent buds on strain that have not a decent yield, i strictly saturate the plants in veg since the very first leaf set. Seedlings or cloning, no difference : i hardened off the two the same way. Until it burn, twist, turn on its hypocotyle to dodge the light density that i’m blasting in their faces. Without any night ^^

It’s not to melt the brix meter with sugar contents, it’s to produce a stone as primary root ball. It directly affect the first month of flowering stage, so the repartition of the buds over the 5th node and the density of hormons necessary to fully join the initial “ping pong balls”.

Anyway, when it’s belonging to yield with cannabis by any way … it’s always directly linked with the roots density and the care you give to them to keep them plushy ^^
