Harvest time

2 posts in this topic


Quick one. I am coming to the end of my first grow and they are looking pretty awesome for my first shot (little video For you all attached). 

What I could do with knowing is:

What PH does my water need be wen I flush?

How long do I flush For?

After my last water/flush do I let my plants drink all till the coco is none dry?

5,8 to 6,2        Even though the flush serves to wash salts and other wastes away from the area of the roots, the roots still need to have their comfortable pH range to be able to continue to exchange nutrients and wastes with the medium, so that the plant is also able to rid itself of salts and excess nutrients.


Flush is 3x the volume of your pot delivered over a short period of time (~10 to 30 minutes depending on the density of the medium).


In coco, you don't necessarily need a dry-out period.  Just overnight is enough.

The idea behind the drying-out period is to help oxygen to return to the roots when in a denser medium, like soil.  Coco is so porous that soon after watering, the water drains away and oxygen fills in behind it, thereby re-saturating the root area with oxygen.

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.
