HomeGrown GH-Flora Coco - Alternative Nutrients for 2020.pdf

 

Weigh out Epsom Salts with 0.01 gram resolution Scales.

Use Syringe with compensated nozzle for liquids.

 

Silica is added at 0.4ml (I ph down water before adding silica, so the ph rise is neutralised).

It is important that ph remains below 6 during preparation, or silica can fall from suspension and become unavailable.

 

Stages of application were loosely based on my 40day skunk.

For most plants I switch from Grow to Early Bloom at around 12-14 days 12/12.

Just give the plant what it needs.

Germination in Rockwool

I have a temperature controlled area 27.6 to 28C or; 81.68 to 82.4F.

A bottle cap of water, placed where rockwool normally sits,

has stable water temp of 27C or 80.6F

 

I soak a single seed in strait rain water @ph 6.2, changing water every 30-40 minutes until seed sinks.

When sunk, I leave to soak another 30 minutes before planting in rockwool point down.

I push the seed down, so the top of seed is 9mm from surface.

Note: If you fail to go deep enough and plant the wrong way up, the root will grow up out of rockwool

 

Nutrient:

GH Seedling Mix.

Micro  – 2

Grow   –1

Bloom – 1

Silica – 0.1

I ph down water before adding silica, so the ph rise is neutralised.

It is important that ph remains below 6 during preparation, or silica can fall from suspension and become unavailable.

 

Rockwool preparation - Note: We use Eutech ppm measure.

Soak Rockwool at 100ppm ph 5.2 and leave for 1-2 hours.

We place soaked rockwool in mesh cage to fully shake out water, without damage to rockwool.

Soak Rockwool again at 40ppm ph 6.2

Shake only 3 times, so block is still heavy and half saturated.

Plant seed.

 

Seed Nutrient application:

I use 40ppm ph 6.2 to resoak rockwool, if needed before seed germinates.

Shake only 3 times, so block is still heavy and half saturated.

 

At first true leaf I use Seedling 150ppm ph 6.2

Third true leaves, Seedling 160ppm ph 5.9-6

 

Transplant to Coco,  Coco Grow 170ppm ph 5.8

Pre Flower, Coco Grow 180ppm ph 5.8

 

This is not a guide, just sharing what I do.

There is no such thing as a perfect nutrient mix, just the right time to apply it.

I put a lot of work into developing Custom Coco Nutrient from General Hydroponics flora products.

We also developed Custom GH profiles for Nutrient Film Technique.

Everything was working beautifully, medical patients were happy.

 

Then Scotts Miracle-Gro purchased the hydroponics nutrients manufacturer General Hydroponics.

 

The company stopped supporting use for growing cannabis and Nutrient Sales in Australia

Product is often no longer available or three times the cost.

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.
