Organic Growers - Can you use RO water?

Haha, don't feel bad. I use old water jugs. If it ain't broke...

Yep :smoking:

I’ll let you know. I’m trying to figure out how to run a hose from my rain barrel into my basement without messing with the integrity of my house. I only have a 3x6 bed right now so I don’t use tons of water and just use almond milk jugs lol.

Haha no shame in hauling water, it builds character! Not bad at all in a small grow. Do yourself a favor and start using a 5 gallon bucket so you can collect plenty in one trip. Use one with a lid so you don't spill it walking through the house

The only reason to use filtered water in organics would be to have water that is free from chloramine, or chlorine which will be detrimental to the microbiology.

If you have well water it can be used straight with no worries even if it has a higher ppm of minerals and micros

I would say this advice can work in many cases, but if you have water that's really high in bicarbonates or alkalinity and your pH is way off it could create issues. And if you are bringing in minerals they need to be accounted for you in your fertility plan, especially if you are in-ground or re-using your media.

I like the recommendation to mix the RO water with the well water to get a lower ppm overall since the RO water will want to bond with something and not be very stable.

Watch that well if you got a water softener

I run straight RO water when I grow indoors. I like knowing that I have a consistent constant starting point. I use all organic medium and dry nutrients and in flower I mix Bloombastic that is organic with the RO water during flower. Happy Farming
