Then drop the attitude.

Something isn't stupid because you personally fail to understand it. This website is packed with information on the why and how, if you fail to make use of it, well, stupid is as stupid does, eh?

Sometimes this conventional wisdom from long time growers with no formal education is fucking stupid.

I'm doing an exact side by side test right now

as I had a few excess seeds

so far 10 liter pot versus the 4 inch pot

the 4 inch pot is about 3 weeks ahead of the larger pot

conclusion: the 4inch pot is about 5C warmer

in same place too

good luck with your 'learning'

So it's just growing faster, but is it a more quality plant? Is the only metric of plant health growth rate? Or plant desirability? Is 10 liters even big enough to plant seeds into? Wouldn't you need something that is at least 25 gallons, more likely closer to 55, to mimic natural conditions indoors?

Your "side-by-side" test is in no way accurate or indicative of anything -- except maybe the difference in soil temperature in different sized pots growing cannabis.

As someone who hates transplanting, things seem to go better when you crowd the roots a bit. Of course I also convince myself to use the shortest widest pots to support my training methods. I start my seeds on paper towels and the faster the tap the deeper they are buried.

If I could sew, I'd probably be using fabric sapling pouches, germ in them. Not sure why they aren't produced. Maybe the roots are too fine and mesh with the fabric?

My experience has shown a plant growing faster in smaller containers compared to those started in a bigger container. For me, that would be the main reason. The other is the luxury of dealing with a smaller volume of medium to keep saturated/fed/flushed, so there can be cost savings/efficiency as well. Those are both pretty damn good reasons to me.

I think you also need to keep in mind that we have folks doing their thing in a number of different types of environments with varying amounts of space and in different mediums.

Essentially if you actually think about it, you can make a laundry list of reasons. Or you can call the method stupid and be a dick.

I use the smallest pot possible. Saves room and materials for when you really need them
I’m sure the commercial types could have a robot poke his finger in the dirt and a drone fly by and do pesticide foliars. Super efficient and no up potting

[Betterhaff]

I’ve started and grown seedlings in 6 pack cells used for vegetables and flowers, you know like the ones you get at the nursery. I’ve even grown some of them in those for a long time due to lack of space, time, or neglect. Pain in the ass as far watering but I always put a reservoir type container beneath it. A lot of times the roots start shooting out of the bottom of the cells and they definitely get root bound. When I transplant I tease the roots apart a bit and plant the root ball deep, inches or so deeper than the original stem / soil line. They may take a few days to rebound but never really had a problem with the health of the plants. Maybe not the best technique but the plants have always thrived, cannabis can be pretty hardy and tough.

If you want to talk about medium and nute use you can’t get much skimpier than that. Those cells probably hold a couple of tablespoons of medium each.

Transplanting does not stunt or slow growth. Growth actually explodes after up potting.

How can someone say a side by side does not prove anything?

What a noob fest

Scale?

That's one factor for me.

You say you started 5 seeds or so before, and soon will start ‘some' more.

Let’s say you’re popping 30 regular seeds. Why would you want to start them in large containers when you don’t know the sex? Let’s say you end up with 15 males in large containers. What a waste, right? Even if you plan to reuse the soil, that’s a lot of unnecessary extra work.

Lots of other reasons as others have said. But this says it best:

In a large pot the seedling shoots a tap root down as far as it wants and then branches out. You are losing the root space of much of the soil in the pot because the roots grow down and not up. When you start them in a small pot the root hits bottom and starts to grow around. You restrict it for a bit in a small container. When you up-pot the roots now can brach out and fill the next size container. When you finally up-pot to the large container you speak of that big pot has roots from top to bottom and the yield will be much bigger due to a larger rootmass than if you just started the seed in the large container to begin with.

That is the reason for up-potting.
