My Grobo Solid has arrived and I’m just starting my first grow(Ya!)
Im in Hamilton Ontario and I was thinking it might be helpful to discuss sources of water.
Im not ready to invest in my own RO just yet.
The local Walmart sells the big 18.5L jugs of RO water for 4.95(plus deposit for jug)
its Culligan water here’s pic of label says demieralized water by Reverse Osmosis
I’m hoping this will be good enough to start with.
Does anyone else know of a source that’s cheaper? Costco seems to just have regular spring water but it didn’t say it was RO so i was avoiding theirs atm.
any need to have more then one? It appears to have used less then half to do the initial fill. maybe its enough for biweekly swaps?
