Hi I have been growing for a while and am conflicted which is better 3 gal or 5 gal fabric pot. There are alot of variables that come into place. Such as the growing space and either running straight coco or mixing with perlite. I know you are suppose to treat the medium like hydro but can run it like soil. So a little bit about my grow I have pretty much unlimited space but as we all know there are only a certain amount we can have. I have an irrigation system where I am able to water as much or as little as i would like. I am currently running 3 gal fabric pot with straight coco and am averaging 10 zips a plant but I know I am able to increase it to over a P with the strains I am running. So if anyone could chime in with experience or ideas about what size pot would be the best for yield I look forward to hearing. Also I am currently running Double Ended HPS but am soon switching over to LED which will make the plants not transpire as much. Again thanks for reading and if I left anything out don't hesitate to let me know so I can better your answer to the forum.
