Pot size for autos

[djdiazemk3]

Hey all, what are your experiences with pot shape and sizes when it comes to autos?

peace

Depends... i got damn nice autos with 24carats,2 plants in 15l. 32cm tall plants with full colas. Check mitch conor mephisto thread

I used 24qt pots and have this size, 1k on a light rail

Depends if indoors/outdoors, average size at harvest. Have seen some astounding autos in Big Gulp cups.

We use 2-5 gallon size, depending if super auto or large or wanting to keep covert.

Autos do great in 3 gal pots w/ good organic soil & regular feeding. As fast growers & flowerers, they're quite hungry.

There wqas a comment on this site several years ago where the writer discussed his experiments with different size/shape containers for autos. He concluded that the plants were strongly affected by the roots reaching the bottom of the containers, causing growth to radically slow down. Container width didn't seem that important. He found good results growing his autoflowers in the long narrow Treepots.

yeah sounds like the advice I’ve had from my grow shop people’s, I’m picking up some 10l/2.5gal deep square pots, I’m going to cut the bottoms off the current ones and place straight in the new deep pots with 60/40 Gold Mix

I have grown tons of autos and it really depends on strain an auto extreme will dwarf a 15-20l pot how ever a fast bud be happy in a pot at 6l. At the mo most non mega yielding strains will do well in a 10-12l ish size pot

 

[djdiazemk3]

went with 7.5l in the end its all they had, nice narrow and deep

I'm more than happy with a standard round 12-15 liter pot ...er thats 3 us gallon here, plant the seed direct to the pot, and not so much nute either,...see for yourself at harvest how small the rootzone is...

Correcto-mundo, Amanda.

Autos don't like to be root bound. Nor over fertilized, nor over watered. Beyond that....they have their own cruise control.

In a really good soil mix & 3 gal pots, I suspect that 70 day autoflowers would go seed to harvest like gangbusters on water alone, maybe a few doses of aerated EWC tea. Blumats would make that even better.

The little darlings will grow & flower explosively when conditions are right.

That's sounds good. I am awaiting on the on 3 Dutch Passion AutoEuforia Autos. I plan on using Wally World bags as airpots and growing in Fox Farm Ocean potting soil. Should be able to do the whole thing on just ph'd RO water. I have 3 other autos in coco that are several days olds but still tiny. They are my first.. Feeding them FloraNova Bloom (3 tsps to to 5 gal of RO water) and 5 ml of Calmag Plus for the first week or so until that batch runs out then I will increase the FloraNova to 4, then 6 tsps until harvest Wish me luck..

So I'm the only one who thinks 4-5 gallons minimum? Have any of you recommending 3 gallons done side by sides with 5+? What's your light schedule? I do 24/0, and the bigger I've gone the happier I've been. I start in largest pot possible to, preferably finishing pot. Id love to put a bed into one of my rooms and direct seed some and see what I can do.

 

[dickcorn]

If you have 12 in 3 gallons now bumping them to five is like 2 more bags of soil, like 40$. An extra q from all combined more then pays that, and I bet you'd actually get quite a bit more for the tiny investment and effort.

 

[aridbud]

Some smaller autos only require 2.5- 3 gallon containers. 5 and we've even grown in 7 gallon containers...plants are happy.

Based on my limited experience, repotting is much more harmful to AF strains than photoperiod strains. Start them with at least a 2 liter container and repot no more than once.

Anything much larger than a 5 gallon bucket is probably overkill unless it is known to be an exceptionally large autoflower strain (4+ feet). AF plants simply have less time to grow roots than photoperiod strains.

When it comes to nutes, I err on the side of caution. Use rich soil and use light ferts, but carefully. If you want the most out of AF's every day of growth every day needs to be ideal. However, a plant with a moderate nute deficiency will ultimately do better than one that suffers even mild nute burn.

It is crazy easy to grow organic AF weed. Start with an organic soil, add light organic nutes when prudent.Ignore anything but moderate to severe nute deficiencies, Wait 60 days and chop.

When dealing with small pots, yield and pot size are directly correlated. Use the largest container you can fit in your grow space.

But i'm no expert that's just my 2 cents.

I personally use 16l / 3 gallon smart pots for most grows

On my current grow my autos got root bound in 1.5gal pots, I transferred to 4 gal square pots, One girl who was in flower took very well alothough didn't grow to the size of expect from a 4 gal pot, the 2nd on was a short stocky thing that stayed in veg for 6 week. In the future I shall be seeding straight into 4 or 5 gal pots just because it makes sense with autos

 

[djdiazemk3]

That's the 1st one that got transplanted during flower, nearly done
