This is very well explained too. I'd like to take your post and link to the swick club thread. Would you mind if I did that? I want to copy Gee's explanation too. I think it is informative for people considering sub-irrigation to have access to this clarity and motivation. I'm just trying to figure out the most effective way to do that. May I? And @Gee64, may I link your explanation to the swick thread?I think that's right. And, it's not a competition. Each grower gravitates to the style they prefer for a multitude of reasons. Your cloth pots may very well grow bigger plants than a comparably sized SIP. It makes sense that there would be more availability of air all around the pot.
All the high growth methodologies like Hydro, SIP, SWICK, and Fabric Pots all share common elements from ample availability of both water and air, and especially air to the roots. They each do them slightly differently but all do both particularly well.
From there we each dial in our own grows. I've said on many occasions that I'm not trying to maximize everything on my end. My space is too confined to grow much bigger plants than I already do, and I don't really need all that much to begin with.
My contention is that every soil mix grower needs to try a grow with one of these options at least once. Simply by changing the container you grow in and how you water (which is sooo much easier to get right) you almost automatically become a better grower.
