@027Hempsei, to save nuts I do believe you can upgrade the rez as the root grows, maybe start on 1 gal, then go to 4/5 gal, which is easy to find a bucket of this size, then you change to the final rez.
You might only need the 55L when it's already very big.
I like the idea of modular processes, that you can adapt and keep a high efficiency.
And it was you! I like to spread the word of Peltier! It's easy and cheap to lower some degrees.
