What type/size pot should i use

Hi Gantron, really the choice of pots is yours. If you're growing autoflower, pot size of 3-5 gal is sufficient. Larger for photos. Both air pots and fabric pots allow for more air to the roots. I'm using airpots now but used fabric previously. Cost is a factor, air pots are expensive compared to fabric or plastic. Plastic will last for years whereas fabric may only last for a few grow cycles.

Fabric pots are amazing. Harder to pot up so should be final destination imo.

I will tell you my experience when I started. I went right for the fabric pots, not knowing a thing other than what I read. It became a nightmare for me. I either had huge fungus gnat blooms or so dry it would stunt production. My next grow in a 2’x4’ tent I used 4 4-5 gallon plastic basic pot with a lot of drainage at the bottom and finding a watering routine was simple. I suggest you get the basic (not cheapest) equipment Lights, fans, carbon filter, tent, light, fox farm trio, a soil mix you get the picture. I found in the beginning if I focused on my watering schedule, feeding schedule and learning LST. Once I got that I started micromanaging my grow. Once you learn something it’s yours forever.

In my opinion, the pot should be chosen carefully considering the substrate, the type of plant you want to grow, and the fertilizers you plan to use. For an autoflowering plant, 11 liters is usually enough indoors, a bit more outdoors. A fabric pot is a great option and works really well, but reusing it is a bit more complicated than a plastic one; you need to clean and disinfect it very well because spores of fungi, molds, or larvae can survive in the mesh. On the other hand, a plastic pot will be easier to clean. Back to the sizes, 11 liters indoors for a photoperiod plant with a month of veg should be fine. If you want to do SCROG or some HST, it's better to go for a bigger pot because the vegetative time increases. If you're using supersoil, you'll need a larger pot to hold more soil and fertilizers and have fewer problems during flowering. Anyway, I think going over 20 liters indoors is almost unnecessary (except for the extreme cases mentioned above). I almost forgot, if you're using coco, the pots can be much smaller; I use 3 or 6.5 liters for autos.

I always use square fabric pots with soil and they're great. They prevent the plants from becoming root bound, supply more oxygen to the roots and drain/dry out quicker, which cannabis prefers. Highly recommended. The pot size you need depends on the plant size you're aiming for and how long you plan to veg. Anything from 11L to 17L will do if you plan to a short veg and then flip - I use 16 or 17L pots when growing indoors with four photoperiod plants in a 120cm x 120cm (4ft x 4ft) space, and I usually veg for around 5 weeks. Come the end of the grow cycle, the pots are always filled with roots to every side and corner, and they look super healthy. I use 11L pots when growing autoflowers outdoors, as I want them to remain small and they generally don't need as much vegging time. I don't know what your grow space is like - if it's in a tent, what size the tent is, etc. - but if I assume it's an 80cm x 80cm x 1.8m grow tent with one plant in it, I would suggest using a 17-20L pot as this will grow a plant that easily fills an 80cm x 80cm canopy. If your space is larger than this, you may want an even larger plant and so you'd need a larger pot and more vegging time. If that's the case, go with something over 25L. Basically, your pot size will limit your plant size, but you also don't want a tiny plant sat in a massive pot, as that brings it's own watering difficulties. Good luck!
