New Grower Vertical Growth

[WHwakestreet]

Hey Everyone,

This is my first attempt at growing. I'm growing an auto NL under 4 cfls (2x 6500k and 2x 2500k), in a space bucket I made. My baby is on day 38 and she is 17"s (42.2cm's), she has grown 11"s(28cm's) in the last 12 days. I believe she has been flowering for the last week or 2 and I have started to give her flowering nutrients and added 2 hours more of darkness to try to get her vertical growth to slow down.

I'm wondering:

When will vertical growth slow down?
How tall you think she will get? (I heard CFL's only penetrate 3 feet, so hopefully not taller than that)
And if she is starting to bud?

Thanks,

I'd stop giving flowering nutes and stick with veg until she stops growing vertically.

At 38 days your vertical growth should be slowing down and stopping soon. When it stops then it's time to switch to flowering nutrients. For more information, take a look at this thread: https://www.autoflower.org/f44/life-cycle-auto-flowering-cannabis-5113.html

Hey WH, we need more info to help you. What soil do you have them in? What nutes are you giving her and how much? Can you give more details on the space bucket? Size, temps, ventilation method, fans, ect? Light hours?

I can tell you for a fact CFLs do not penetrate 3 feet, it's more like a foot or less and that's from the bulb, not starting at the canopy.

Since you already have her on a flowering nute regimen I would stick with that, switching back and forth between the two could stress and confuse her.

You do have something funky going on with her, she shouldn't have curly, wispy tips on her terminal leaves like that.

Can you tell me the ph of her substrate and what PH you feed her at?

Interesting! I'm thinking about setting up a spacebucket for a life long friend. I want to follow your grow and see how it turns out.

Thanks for all the replies, here’s some info:

I have her in a mixture of 1/3 promix, 1/3 mg organic, and 1/3 perlite. I’ve been giving her a generic nute, (plant prod for flowering plant 15-30-15) every other watering (so basically once a week) at 1ml per 1000ml.

Bucket size: 5 gallon bucket, 11”s wide 14”s height. Then I have added 5 bucket tops each 3.2”s tall (16”s). Total height of the entire spacebucket is 30”. Base has 4”’s of soil, top has 3.2”s for lights. Currently the top of the plant is 6” away from the lights.

Temperature is 78F at the top of the canopy and around 71F at the bottom during the day and all around 68F at night.

I have 1 intake pc fan (30cfm) now under the canopy and 2 exhaust pc fans. 1 is just under the canopy and is 32cfm and another is just below the lights at 28cfm. I run then full speed during the day and about half speed at night.

Lights were 4X6500k for the first 4.5 weeks running 18/6. After 4.5 weeks I switched to 2x6500k and 2x2500k at 18/6 and a few days ago switched it to 16/8 hoping to slow vertical growth.

Yeah I noticed that curl as well, I noticed it first when I gave it flowering nutes, gave too much I believe. It went away but I think she got to close to the lights yesterday so I raised them today.

Unfortunately I cannot tell you the PH as it is pretty difficult to get to the soil without manhandling her since she is so bushy. You cant see it in those pic but they is a water hose that sits on top of the soil so I can pour water in from the outside because I thought due to the very small size of the space id have trouble reaching the soil… unfortunately I was correct.


Thanks for the link muddy. I have actually been using that a lot and that’s partially where I got the idea to switch the nutes to try to slow vertical growth.

“If the switch to flowering nutes is made at this time the vertical growth will stop and the plant will put it's energy into producing buds. If you need to keep your plants small, or want them to finish earlier, they by all means switch nutes at this point.”

Thanks for the help everyone.

Here is the water hose and the location of the intake and first exhaust fan. The exhaust fan has a cage over it now so the leaves don't go into it.
