PH and best desired PPM levels for hydro?

What do you think the best desired PPM and PH is for hydro set ups?

PPM for both veg and bloom.

I Use botanicare cns-17 line and I'd say under a 600 or 1000w a good range is 700 for veg and climb to 1000 for flower. Not including the ppm of the tap. So including 300ppm tap water youre looking at 1000 veg- 1300 bloom max. PH never above 6.0.... more like 5.5. This is my experience with DWC not sure about other hydro methods. If you flower with PH above 6.0 the bud formation seems to be massively stunted.

PPM for my water is around 220
im sitting at 1118 for PPM now and PH at 5.8 and air temp at 78.4

i am doing ebb and flow top drip with it being 24hr drip, and usually I run 30mins every hour.

If you are getting return water back to your reservoir then you can look at the testing of that after a 24hoyr period.


If your res tests increase in ppm you're feeding too much.

If your res tests decrease in ppm after 24hours then you're feeding too lightly.


IMO the idea is to find the sweet spot whereby your res returns back at pretty much the same ppm that it was set to.


The sweet spot will change depending upon plant growth.


Hope that made sense.

Yeah it makes sense, I'll test levels tonight. Gotta transplant one of my plants in a bigger pot.

Transplant in hydro?


That's kinda defeating the object.

I always read that hydro is small roots big plant due to direct access of the nutrient ions in the feed source.

Soil plants need large pots for root mass due to organic matter needing converting into inorganic ions for translocation.

I had them in 1 gal pots, or at least 2 of them. I transplanted into a 3gal pot.
