Hey mate! :howdy:
I see your going with some TLO! Wait until you smoke the buds... If you've never smoked organics you'll be in for a full flavor ride
That article must have resonated with you a bit, like it did me! EDTA's are rough eh?!
I got my RO system from ebay for cheap. I think it was $150 or some thing. It was a 5 stage one too. 3 canisters plus the 2 smaller ones, and a 20 gallon reservoir.
When i am not using RO, i use rain water.
Anyhow... I'll be checking in. Also can offer some advice on the organics. Since i've done away with my bottles again, and gone back to TLO style. It's dead easy.
