They are stretching too much on vegetative, can I control the height using super cropping ?

[ForestSpirit]

Just by measure, when the light meter hits 1k ppfd that's too much and she needs to be tied off in one direction and something less than 900 ppfd I start rearranging with wire ties. I hardly clip when there is no crowding but the next two are coming up so there will be more training..

I've heard somewhere that comfortable lighting is 400-800 ppfd, but I've noticed that 400 is always good, and it seems to depend on the plant.Of course, this also depends on the CO2 level and mineral nutrition.

I think that's over cautious. I don't get light burn or high temps so it's not causing symptoms. Fat round tops too so no foxtailing. I don't run enough plants to do a comparison but there is no harm in getting more light without damage or symptoms.
I target 200-350 for a seedling and 800 in veg. That higher number is flowering but I've never seen it burn veg in those ranges either.

I haven't seen any light burns, but I have seen the upper leaves lose their shine and become dull, while the leaves inside the plant remain fresh. I believe this is the moment when the plant stops photosynthesis in certain leaves and redirects its nutrients towards broader growth. While genetics play a significant role, it is still possible to influence the plant's branching pattern.

Updating... the grow is tidy, controlled, plants are healthy and they are stretching fiercely!
I am still with fear about the height they will get, anyway I have to keep going, end of this week I will do another foliation and add 2 more oscillating fans, I hope the humidity decrease(now it is 55%-65%) and I don't need to buy a dehumidifier(expensive device and more energy cost).
Since 7th October on flowering stage, all them showing up the pistils, I am excited!
Outside is 95%+ humidity everyday bro...It is killing me, I don't have a separate room to grow, my studio has only 1 big room and maybe I will have no choice... buy a dehumidifier or lose all that work I did(lot of money and time)!!
Like it still has 6 days on flowering, It is the perfect time to improve that humidity asap or I will have problems...

Recommendations?

Thanks

You have at least a foot plus vertical in your light to go up.

Yeah, I know. It is close to 50cm as I already measure it, If needed I can put the in-line fan and filter outside...and I can hang the light directly on the top bar, It will give me a total of 1 meter more space, it is more than enough.
Cheers!

Filter and fan can also start at the top with a filter, go down a corner, and out a bottom for the same flow but also space round shape pots never use.

That is a lot of ways to use the air system extractor, for me the best is outside bc all the corners, practically all space of the tent is crowded even in the corners, next time I will spend less time on vegetative and It will be perfect for the height and space in general. It will be easier next grow for sure!

Hi there!
Guys, does the charcoal filter remove all the smell, or is it normal for there to be a slight smell, like if you put your nose to the duct, can you smell it? Not very strong, but you can smell it? I'm thinking about buying something to neutralize this smell, man... or my Carbon Filter is just bad(not old, just 3 months)...

Try putting a filter on the other end of the pipe where the outlet is.The person who came up with this method of placing filters doesn't understand physics well.I suspect that the filter itself is small.To reduce the wind speed, you can use a longer and larger duct.

I bought a new carbon filter today from AC Infinity XL 150mm, ONA Gel PRO to control the smell and a new duct bc my ferret scratched it...lol

MOST of a grow smell is identifyable by people as "greenhouse smell". Get some random houseplants and tell them you like having a lot.
Flower tent you're on your own, I'm legal so I haven't solved that one. You're on the right track though!

Definitely going to have a Forest on yer hands. Right side looks a bit heavy. Hopefully you can spread them out fer an even canopy

I need 100% odorless , You can stand in front of my door that it is safe 0 weed smell, but It still in the 3rd week, so it will getting more and more smelly.
I think I can do it with the AC Infinity Carbon Filter XL 150mm, it is super effective to clean the smell of weed, probably 90-100% accordingly with reviews.

19th day of flowering updating... I know I still have to lollipopping them =D

 

[ChairmanFester]

You know what, it's all nice, neat and organized and you knoww the numbers so that is 10 steps ahead of a lot of people lol.
Going further as airtight could be fun. Calculating pressure in and out to balance a low negative pressure carbon inlet and exhaust filters... well you'd have the opportunity to play with supplemental CO2. You could run the outlet airline into a fish tank of aquaponic plants with a little additional pressure to bubble it, and that would be totally rad one off stuff. MAybe raise a turtle in it because they stink lol.

I am so happy with your words!!! Thanks! As my first grow it sounds really good!
The exhaust duct outlet will have another charcoal filter, then one at the beginning and another at the end, but that will probably be done next week. I'm still waiting for the new AC Infinity XL 150mm charcoal filter to become available. But the smell still controlled!
I did a lollipopping today, I'll post some pictures later, as everything is new to me, I need to know if I'm doing a good lollipopping, if I'm cutting it right or not.
Let's getting into the final stage! I am so happy!
All will be done until Christmas bc I have plants that need 9 weeks and others 11 weeks of flowering!!

I trim selectively, I take low small buds but ones more than a dime size nothing. I think and totally could be wrong, they low cost boost hormones.
I take about 15% which is less than many people. I try to leave any well positioned leaf so they can make food.
I'm getting to find out schedules are more like the weather than anything set in stone.

They got light burning… anyway I already lift the Light to 30cm and PPFD to 850
The Light was too close and PPFD 1100…
It was because the “ExHale CO2 Bag” didn’t reach 800+ PPM like I thought…only 450-550 PPM.
But It was only in 3 plants, 2 really soft damage and 1 on the tops and lowers buds, but not heavy damage.
