Yeah they look great I was trying to find something similar where I am but had no luck so far, will keep trying cause surely those things are hiding somewhere here I just haven’t come across them.
Those SIP’s would be great for seed runs for soil growers without much space. Soil capacity is 3gal from memory the buckets had 10L markings on them. and the res buckets were15L from the markings.
The big boyz can be used for keeper runs,maybe just thinking out loud.
