I think I understand the point you're trying to make. You're saying that, for the Ebb & Gro, the inner buckets 'stick' in the outer buckets, right?
I had not really noticed that, but after you brought it up, I guess the outer buckets do seem to lift up sometimes when I am removing the inner. It's not been a problem so far in this grow, and I don't recall it being an issue when I an Ebb & Gro back in the 90'
I'm skeptical about some of the advantages you're claiming. I'm sure the net pots will affect the structure of the root mass (this difference being the potential issue I mentioned above), but I don't really see how it will impact the other items you listed. Since I lack the experience you have with the Titan system, until I can compare them myself, I'll just have to suspend forming an opinion regarding the advantages of a net pot. I think there are net pots available that will fit inside the outer buckets. If I can find some, I will do a test in my next batch.
I mean no disrespect to yourself, or anyone else, by questioning things. I'm just a very inquisitive and logical person. While I don't consider myself a newbie to growing, it has been awhile and I am not an expert. That being said, I will not adopt a belief based on who else holds that belief. If that belief is based in logic, and that logic is explained to me, then I may adopt that belief myself.
When I was a kid, "because I said so" never worked with me. My poor mother used to get frustrated because I always wanted to know "why?"
I certainly hope none of this comes across as argumentative or disrespectful. I learn a lot from what people post on these forums and really appreciate all the valuable experience others share.
