parts for katky hydroponic tomatoes

My simple stupid sytem for Katky hydroponic. I use 40L buckets. Holes are made with a bell saw and i use standard net cup of 8cm or 3inch.

Holes were made with a bell saw turning reverse direction than for wood to not grab the plastic but more slide on it.

Everything is printed in PETG black with 4 perimeters. You can use draft settings with 0.3mm layer height maybe for the funnel you would like to use 0.2mm.

I use Masterblend as fertiliser and refill by 20L so that i don't have to do it too many times.

To know if i need to refill the bucket i just lift one side with one hand to get the weight and ear the water.

The hole in the support is to put a rope that you can turn around the tomatoes for support.

Have Fun.
