Arjan Haze #3, Big Bang, The Cheese correct PH & EC

[anguscr 290]

I'm growing in a DWC hydro system the following strains: Arjan Haze #3, Big Bang & The Cheeses. Here's some a pics:

Arjan Haze #3

Big Bang:

The Cheese

I was wondering, since in the videos on the GHS web site, Franco refers to the PH & EC to grow in soil, wich will be the correct PH & EC for hydro?

Thank you

hello, my friend,

In the green house videos, Franco is using rockwool as a medium.

Therefore the EC is the same.

Ph is different;

Rock wool is slightly alkaline, so the nutrient solution as to be slightly acid to compensate for this.

In other mediums:

if Franco is using a Ph of 5.7 in Rock Wool, then in other mediums the Ph should be 2 to 3 points higher; and slightly more neutral in Ph;

therefore, if, in Rock wool, the Ph is 5.7 - in other mediums, the PH should be 5.8 to around 6.

happy growing,

john
