I've seen people mentioning it, but wanted to get some kind of numbers from the more advanced growers on who's doing it. Thanks guys!

When I first started I would let my jugs of tap water sit for a couple of days, but I eventually got lazy and started sitting my plants in the bath tub and turning on the faucet, giving 'em straight tap water. Never had problems.

if you can drink you tap water so can your plants.

my god, people who buy distilled by the gallon would be better off buying herb. i couldnt imagine what my costs would be like if i had to buy my water.

I don't know of any reason why the mineral content of the water would be bad for the plants, could actually help the higher it is. Chlorine, I know they seriously hate it, so I can see more of a reason for running it through a carbon filter. Humans hate it as well, it's the only reason I can see against not drinking tap water, but a filter jug will solve that. I should have added an option for rain water. Buying that much distilled, I'd have to see some serious gains.

there are guys who buy every drop of their water...blows my mind. rain water can be great or aweful, depends on the pollution in your area. L.A. rain is no doubt not good.

your right, for the most part the mineral content is beneficial. the big benefit of RO is that you know EXACTLY what is in your water, not just that there is 240 ppm of something in there.

and you dont need a filter to rid yourself of the chlorine in tap water. just let it sit out overnight(some say 48 hrs) and the chlorine outgasses(evaporates)

R/O is consistently the best.

agreed, but you can grow perfectly good herb with decent tap or well water.

its my opinion that for smaller personal grows RO goes on the "not neccessary" list with co2 and swiss bank accounts.

Well said

I used to get all my water from my refrigerator which has a carbon filter. Now I just get water from the tap and let it sit for a little while. My plants look better now than they did when I was using the filtered water. That could be other things though like me just getting better at growing. Basically though I haven't seen any benefit from a carbon filter.

Interesting read, thanks! Anymore votes? :P
