About this deal
The greatest light intensity (and thus the fattest buds) is right underneath the light, then decreases significantly toward the sides. This could make growing fewer plants more sensible, as you’ll probably be sacrificing yield to poor light spread if you cram in too many. There’s no point in depriving any of your plants. Whether you chose coco, soil or hydro the Air-Pot allows your plants to develop a remarkable radial root system that simply cannot be matched in any other growing container. Air Pot actively enhances the quality of the root systems of plants. I'm sure a 3L jump in pot size from 15L to 18L won't manage to double the yield, the way the smaller pots with a 4L jump managed.
Several factors influence the number of plants you can reasonably fit per square metre, from the available space in your grow room, to the size of your pots and the type of lights you're using. So there's a few things that you need to look at before deciding, and then decide on what's practical for you No, mate. I was adamant that he wouldn't need anything bigger than an 18L pot, he was adamant that he'd need 20L minimum, possibly even 25-30L.

Modern LEDs can output the same light intensity as HPS units, while using around 60-70% of the energy. Therefore, they cover the same space in less wattage. A good 250W LED is equal to a 400W HPS, which can cover around 5–6 plants. By comparison, a high-powered 1200W LED should be able to cover around 8–9 plants.
Outcomes: Challenging to perform, consistent results, options for beginners and more advanced growersEven those without significant spatial limitations tend to choose shorter cannabis varieties when growing indoors. After all, you are responsible for providing illumination, so you need to account for the space taken up by your grow lights. Moreover, if you’re growing different strains and some end up being much taller than others, this can deprive smaller specimens of light, resulting in stretching and reduced final yields.
Just in my mind 4 x 15L is a 40% loss in root medium which is a massive amount so I would just feel happier starting with what I before so there should be no yield drops. ie you wont be pushing a 25L pot to do 9oz but it might be the upper end of a 15L (not sure in coco). The design of the Air-Pot container and the amazing speed of growth that it will make possible, means that some small changes will be needed to get the best results. EG..600grms = 21oz so if using 9 plants 600/9 = 66grms/plant which is just over 2oz. A 6.5ltr pot whether in compost or coco will produce that size of plant consistently if like I said earlier its grown in a good environment. I cant see the point of using big pots if only needing a couple of ounces per plant. By the time a large pot has rooted out the plant will probably be too big and you will have had to top or supercrop to keep the height down plus its just wasted time He seems to think that he'll need a pot size that's over 20 litres, to get the required 9oz's from each of the 4 pots to make up the GPW.If using 4 plants then you would look for them to yield over 5oz/plant so then you would need at least an 11-15ltr if in compost but you would get away with 11ltr in coco. Coco tends to out yield compost by more when you get to the bigger pots. Training would mostly be used for smaller numbers to fill the canopy product/helpAdviseTab.hbs -->
