I thought that I feel threatened after all and that it's time for a counterstrike
I happened to come across some 'faisselle' (a sort of French curd cheese) which is sold in a 'faisselle' (a perforated mold to drain off the whey).
I got some new yoghurt cups, fetched some tools (pic 1) and got to work, put some metal wire on the faisselle (pic 2) and at first perforated the cups 'Hempy bucket style' (pic 3). Then I thought I could/should do better and got me some straws, glue and a cutter to make an easy way of 'water level control and drainage system' (pic 4). The result is on pic 5 and I'll show you the poted plants as soon as I have them ready
Ahh... forgot to say: I have the hope that this 'faisselle thingie' combines only the advantages of soil, hydro, and hempy buckets. I won't do real hydroponics because I have no idea bout that but with the faisselle I can add additional liquid 'superfood' and remove if necessary via the straw, the roots get more air and there's no toxic salt build-up like I've often seen with small pots.
