Reverse Osmosis can cause issues

[Lynhal]

This is not different than saying "Watering can cause issues". Everything can cause issues if you don't read the manual first.

LMAO@if you don't read the manual first. ostreadrulez:

your right he sort of said that but he was hardly clear on the fact that you could actually use RO water and didnt explain why it would be better to use RO water. If anything i just cleared up why you would want to use RO water.

Quite right!
There's a lot to be said for starting with a "clean slate".
Always best to minimize the unknown.

Coco nutes, if they are any good, create a perfect balance with distilled or R/O water.
And the ppm. actually means something when you start with 0.
Excellent points for coco and hydro!

I have found however, that low ppm water kills cuttings by drawing mobile nutrients from them through osmotic pressure.
You might want to look into that.

thats a good point and i agree with you. I always use tap water with my cuttings. The reason being that I don't really add that many nutrients in the beginning. I never really knew the science behind it but I figured out from trial and error that the plants would need the extra nutrients in the early cutting stages without me actually adding them. Never knew it was because of too low of PPM. Thanks for the info. Now i know i'm doing it right.

Stagnant water drowns plants, allows pathogens to flourish, and rots roots.
You want it sparkly fresh from an aerated faucet.

Been following this advice for years and it has served me very well.

Other than that, your advice is excellent .:thumbsup:

I use great white and the chlorine from fresh tap water kills all the helpful bacteria that i'm trying to add. So thats another reason i use RO water because I am able to add great white without it killing my bacteria. The best route in my case for the early stage is to use a carbon filter to get out the chlorine and not take out all the other good things in the water.

yup RO and distilled can caseu problems, however when problems are solved you have better controll over your hydro systems, or soil grows. also salt bulid up and flushing is less of a issue, final flushing can be done in a week in coco everytime, and the same with hydro, and still reach optimum flush in the plant. however I realy think that money spent on a RO filter system could be better spent on a omni water molicule system. making the water and nutrients more availabe to the plant. (I also dont know and have never used much of the omni but I understand that making water an nutrient more available to the plant is better than more filtered water)

Weezard, I thank you for your additional information and for correcting me. I appreciate that.

For those of you who dis believe, try growing with just soil, and no nutes...as I do...you will see.

Yup, I tried. It definitely works perfect for "carnivorous plants". Sphagnum peat moss, distilled water (RO water is OK too), no nutes. They had beautiful, colorful trichomes which were catching insects. And they were flowering very well.
Don't know about the other plants, if they can survive in these conditions. Maybe sticking some bugs on trichomes can supply some energy for them too

Hmm, wonder what ladybugs would do if added? ... that is a point I will ponder for a spell.
