A modular based hydroponic tree, fits 2inch netcups (or print them too). Sit the tree on a bucket with a lid, fill it with nutrient, pop a water pump into the bucket, feed the tube up the center and connect it to the spout at the top.

Printed best (and quickest) with a .8 nozzle, but can print with .4 (increases time).

Best printed in food grade material such as PETG (as PLA is somewhat water sensitive)

UPDATE: I have found that .6 nozzle seems to be the best of both worlds, decent print on .28 low quality and .2 standard quality heights, and pretty fast expsecially with cura 5. set seem to back and print with pod facing forward. I get 5 hour prints on the pods now in PETG with decent results.
