Default Doubling Up in Containers

If we look at the POV that dirt is just the medium/means for roots/water/nutrition, dare I double up in 15G pots. Just thinking/looking at AKMarks setup - in which he doubles up in 5G containers. Granted, to some degree, he is in a controlled enviroment.

For me, it's 15G fabric pots , outdoors. I was not planning to grow as many this year, but due to Marsha's incredible generosity, I'm trialing some.

So here is the list that I'm considering doubling up in 15G containers.
Whaddya say, yay or nay.

- Mat Su
- Pruden Purple
- PBTD
-GGWT

-Reif
-Wes
-SG

Granted, I've alway planted single plants in a pot and they all fill the entire space and cage - unless I get hit with blight.

So is double up doable / advisable. Or give them space to breath and light ?

It is definitely do-able (Marsha grows 2 per earth box, IIRC). You would have to keep them to 1 or 2 stems max and keep everything well trimmed.

In terms of volume it's doable especially with automatic watering.

Now the second problem is spacing. If you leave them unpruned they'll just grow into one another which is not great. You need a way to train them a certain distance apart. The earthbox is kind of long-ish which is an advantage for this.

I see what you're saying Zipcode re: the EB.

I just looked it up. The EB's surface foorprint by 29W x13D
Don't know volume

My 15G's are 18" round.

I suppose as a different POV/Approach, is that 2 plants will have *2 roots systems*. Prune the stems so it's manageable but because the root system is feeding ~less~, it might be more productive ?

Well, the root system will be more or less proportional with top growth from my experience.
So prune more means less roots as well. Earthbox has 15 gal afaik.

2 plants pruned to one stem will do great in 15 gal.

Will that produce more or less than one unpruned plant? Well, I don't know, you can always test, but you get to try two different varieties.

I've grown two per 10G rectangular Earthbox-type container. I didn't like the result. Where I lived at that time had previously grown potatoes, and it's humid, so I had a lot of disease problems at the best of times, and for me, the tomatoes were just too crowded. But my container was a 10G, so smaller than an actual EB.
