I just cut the top offa 1 litre tetra pak and noticed it completely blocks light which might make it suitable for hempy growing.

If you kept the size down in a sog style, would a bunch of these make suitable pots? What is a reasonable minimum size for either 12/12 from seed or clones in a hempy?

I've just had a nuts idea about a hempy colluseum type grow using tetrapaks and drain pipes...
