What is your solution made of and how often do you have to change it?
It is mainly a water extract of home made compost its colour is deep brown also i use chemicals 0.5 gm of ammonim nitrate+0.5 gm potassium sulphat + 0.5 ml of phosphoric acid (sometimes i may add 0.5 gm of urea) for every 1:1.5 liter of water
Till now (5 month) I don't chang the solution.
Are you not concerned about using oil containers instead of food grade containers?
I agree with you , PVC pipes is also harmfull, every things here(Egypt) are polluted.
