hi i used about 6--8g in 10l and my water had a ph of 8.5 - 9 before i added pf after i added it had ph about 6,2-6,4 so it might get acidic when u allready have a ph of 6 (5, 8). someone should know this.


after reading dust's reply i remember i corrected ph before adding.

When i used the PF with my water it took the ph sliiightly down like 0,1 or 0,2 max.  What kind of ph tester do you have if it is an electronic one it should not be too dificult to check even for a novice :)


And in 5L i would put more around 4g it depends in what stage they are, if in veg around 3g, if in flowering 4 to be safe, 5 will bring the EC around 1,9 depending on your water.

Good luck man

You should always check the PH after mixing it well and wait say 10 min.

My water is 6.2-6.3 most of the time. 10L mixed with 10g makes it 5.8-5.9. Then I have to bring it down slightly to 5.6 , when in veg (using GH Hybrids). Now in flower - it's just right.

About us

Strain Hunters is a series of documentaries aimed at informing the general public about the quest for the preservation of the cannabis plant in the form of particularly vulnerable landraces originating in the poorest areas of the planet.

Cannabis, one of the most ancient plants known to man, used in every civilisation all over the world for medicinal and recreational purposes, is facing a very real threat of extinction. One day these plants could be helpful in developing better medications for the sick and the suffering. We feel it is our duty to preserve as many cannabis landraces in our genetic database, and by breeding them into other well-studied medicinal strains for the sole purpose of scientific research.
