Root mass in relation to yield?

Hi All!

I have read many people saying with a larger pot you will get more yield.

I am currently growing in 4 gallon pots, and I am yielding around 1 pound per plant. If I had to go to an 8 gallon pot, all things being equal, will I get more?

I feel I wont. My plants are doing great in smaller pots. I am growing in coco and feeding twice per day.

Thanks for any advice!!!

I have read the same things. Im only half way through my first ever hydro grow and this is only my second grow ever, so Im a looooong way from an expert, but thats one of the things I wanted to test in my 3way hydro grow.

I cant say how the yields will turn out yet - 4 more weeks to go - but so far, root mass does not seem to dictate plant size or growth rates.

Im running three clones from the same mother - one in an E/F tote, and one in an NFT tote and one in a Membrane Meniscus tote - all in the same tent on the same nutes with the same lighting, same temps, same PH, etc etc.

I cant tell for sure how big the root mass is in the E/F tote, but Im guessing it is somewhere in between the other two. The E/F tote got a head start on the other two as far as root growth because I was stupid setting it up. The Membrane tote has a much larger root mass than the NFT tote - by at least 4-5 times, yet all three plants are, as close as I can tell, the same exact size and all three look equally healthy at this point.

For a while, shortly after changing to 12/12, the Membrane tote had the first, largest, and most developed buds of the three, but they are all looking very close now with the E/F tote lagging just a hair behind the other two.

Generally, yes, if you can fill the pot with roots and keep reasonable wet/ dry cycles. Eventually you'll get to a container size that's just to big for the plant mass and won't benefit you and can actually be detrimental, keeping the media wet for too long. Doubling roots doesn't mean double yield, it's not linear, theres a bell curve. There's also other variables and yield is ultimately based on foliage mass. Slightly smaller volume with more watering cycles is generally better.

At a general level, assuming you can fit the same number of plants in those size containers, etc etc, then your plants will grow to be bigger and be capable of yielding more....what is your medium?...Since this is under the hydro section I'm assuming you're growing in hydroponics?

What’s your lighting n setup?
How much area does each plant get?
