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.
greg1317 Reviewed by greg1317 on . Reverse Osmosis can cause issues I am learning over the last 2 years that RO water is not a good idea for our plants. RO is so efficient that it removes good nutrients like calcium, magnesium, iron, potassium, zinc, and many others. Plants become micronutrient defficient. I now feel that if a person uses RO water they need to replace ALL micronutrients. And because mixes and ferts expect those micronutrients to be present in the water supply, the plants can show many different forms of stress, the most prevelent one Rating: 5
