PKSTN - UPDATE/REDESIGN
Pakistan as well russian system have updates. Find originals online.
Pakistan system by:
1. screwing/unscrewing the cap - thus the pressure of the water regulates the opening and thus the amount of drip: more in the beginning, less later, as the pressure gets smaller. At times one needs to re-unscrew in the middle of the emptying of the bottle.
2. removing the bottom, to allow for lemna to grow, to block the algae from growing, to add a level of supplying water to insects because they can land on the lemna, and reducing evaporation, and providing mulch materials.
System not in use atm.
