@Gee64 Storage totes work very well in spacially limited locations, like the avg grow tent or room, but also outdoors where most people are likely to have a little bit more elbow room. The choices of shapes, sizes and availability of good totes is unparalleled.
In space-usage terms, rectangular shapes are much more efficient than circular ones, allowing the maximum volume of soil and therefore nutrients, in commonly found growing spaces indoors, for the plant's benefit.
Creating a false floor inside the tote can be accomplished in multiple ways, including using the lid and cutting it down. Special tools help here, but you can do what needs doing with multiple hand tool options common to most households. If you are interested in researching the salient details just DM me and I'll put together a bullet-point doc that lists my personal, considered, DIY SIP essentials and best practices, and maybe some pros and cons regarding the different internal methods used - like perlite wicks, small wick, large wick (lol).
In all seriousness, if I can be helpful please feel free to ask (and not to), and good luck with whatever you're getting up to. Honestly, I wrote to thank you for your role as a helpful and interesting member. I appreciate your contributions, long may they run!
