Big Pots = Big Trees, Little Pots = Baby Trees (COCO)

Just wanted to share, the little plants in the first picture are in 3 gallon pots of coco/perlite, same veg time and nutrients etc as the 15 gallon plants. The first pic was taken 7 days before the second pic in 12/12. These were moved to flower 14 days ago. So many ppl on here say its a waste to grow in big pots of coco. I think this is proof they're dead wrong. Big Pot Gang

I think it proves that having a light over the plant helps more. I am not disproving your test, but the smaller pots are also on the ground while the bigger pots are raised, and the smaller plants are in the shadows of the others with no light, not really a good test in my opinion. Next time put the big pots on the ground away from the lights and the smaller pots directly under lights and raised, with the same results I would say proven, not from what you are showing. That’s comparing apples to oranges.

Along the lines of pot size. I am going to try to grow a whole plant in a 6 inch Hugo rockwool cube or rw slab... I don't like how the slabs are not deep but 6x6 for a cube doesn't seem very large either. Thinking of.stacking 2 6x6 cubes per plant.

Anyone have any input when it comes to the large cubs vs slabs?

the bottom halves of those plants could use some side lighting

I worked with a guy who had a literally tree, over 6 feet tall, with a trunk the size of my calf, in a 4inch cube on top of a Hugo in one of those slim flood trays. The roots came out about 3 feet from the cube and clogged the flood/drain kit, so twice a year we would go in and cut them back.

It's not a scientific study. General observation. 5 gals under 720w LED 1200 PPFD

10 gals under 645 watt LED 1260 PPFD


You can see the 10 gal are wayyy bigger as 3 5 gal make 1 10 gal in the same space. The yield on the 10 gals was 12% higher than the 5 gals too.

That is insane, but that sounds more like ebb and flow where the roots weren't limited to the 4 inch cube, especially considering you had to literally cut roots..

I agree but prefer to not add the expense. lol

It was, but as long as there's room for roots and propper irrigation, they will just keep growing.

I use 3 gal with coco/perlite feed 2x daily in fabric pots- drain to waste-They are the correct size for my room to flower 6 at a time- if I did 5 gallons I would probably only fit 3. So for me it helps control my grow to fit my space- plus I like the odds to get get through flower with 6 and have a decent yield-no guarantee a plant will make it-
That is an awesome setup- wish I had the space- great job

Sounds like you got it planned out, if my setup was smaller i'd run 5 gals admittedly. I take the space for granted and try not to all the time.

I think the major thing here, if you have genetics you know can grow real big and good then a large pot will be better for some than a bunch of small pots. Obviously you'll have to use more water less frequently to keep everything saturated which means usually higher feed strengths and also input pH.

Oh for sure. EbbFlow has tempted me in the past, I never did it because I always have had good results with coco and my property needs a lot of holes filled.

I stepped down from 15 gallon pots to 10 gallons. The difference in how my crop is turning out in 5s side by side is just discouraging. I understand if you veg a plant for 2x longer in a 5 gallon it will come close, but unless your growing at scale doing hundreds of little plants it just doesn't really make sense to me.



Same strain in 7 gallons, same veg time..


I understand at scale it wouldn't make sense to use anything larger than a 3 or 5 gallon pot with fast turnover, but if you are a home grower who wants to harvest the largest plants possible without compromising quality, there is no reason to avoid large pots.. The idea that a small pot will produce the same amount of weed as a large pot is completely wrong. Small pots require way more veg time and still will not compare to the yield os a larger root mass. Regardless of feeding style/frequency.
