Rock Machine Auto, Coco Hempy Bucket Mini

The seed spent 24 hours in a glass with a couple drops of peroxide and released a root, then it was planted and after 1.5 days broke through to the surface. Rusty will be in a cut bottle of beer volume 1.5 liters. Maybe a little less. At the bottom of the bottle about 6 cm of coarse perlite and a single hole in the side just below the level of perlite. The rest is coco. Goal: to grow a small plant and water it only a couple times a week. 10-15 grams dry would be enough for me. The necessary nutrition will come from the bottom of the pot where the perlite is. The system is called coco hempy backet. It's a kind of passive hydro.
