starting cannabis seeds in coco coir

Watering and feeding cannabis plants cultivated in coco coir is a relatively simple transition for hydroponics growers and organic growers. Generally, hydroponic fertilisers perform better than most brands’ organic soil nutrients in coco coir. Specifically, coco specific nutrient ranges are worthy of consideration.

Taking the extra step of adding a nutrient supplement, such as the RQS Easy Combo Booster Pack, will provide your plants will all the minerals they need throughout the vegetative and flowering phases.

HOW TO GROW MARIJUANA IN COCO COIR

Low-grade coco coir bricks can sometimes be overdried. Occassionaly they can have odd sizes. Worse, some can be really tough to break down into usable growing medium. No matter how much water you add, bunk bricks won’t crumble easily.

Coco coir is the recycled and processed natural fibre from the husk of coconuts, grown mostly in India and Sri Lanka. What was once regarded as waste material, in contrast today constitutes a magnificent growing medium for cannabis plants both indoors and outdoors. With a pH of typically between 6.5-7.0, coco coir is comparable to unfertilised soil. Coco coir is available from most grow shops in 50l sacks. It’s sold just like soil. But usually more readily available in tightly compressed coco bricks.

The simple option is to purchase high quality nutrients with pH perfect blends. Alternatively you can use standard hydro equipment. A pH meter and bottles of pH-Up and pH-Down will do the job. So you can either let the wonder nutrients work their magic or dial in the old fashioned way.

Yeast tube Caps – Available at Home Depot.

Peroxide 3% solution.

Do your best to create a clean room. We used a kitchen island disinfected with 91% alcohol.

You want to create as close to a clean room as you can get:

We’re going to assume not everybody has access to this kind of a setup. So as a stand-in practice, Frank recommends bleaching your bathroom clean and bringing in an air purifier.

Test Tubes—Frank recommends laboratory quality glass. Cheap test tubes will break when you sterilize them. While all of these materials can be purchased at Home Depot it is possible to buy a quality tissue culture kit for under $150, thus saving yourself a lot of running around.. Microclone.com – produces good basic kit.

The conditions under which the cannabis seeds have been stored

A grower’s germination rates (the % of seeds that yield a viable plant) vary based on a number of factors—these include:

When should I start giving my Coco nutrients?

Similarly one may ask, how do you use coir seed starters?

Also, how often should I water my coco coir seedlings? The frequency of watering depends on the evaporation and the water supply in the COCO. A common rule is; one daily watering is sufficient during the first few weeks under normal circumstances; then increase up to 2 times a day; 2 hours after the lamps have been turned on and 2 hours before they are switched off again.

COIR SEED STARTER PELLETS (Pack 20) Ideal for growing your own seedlings or cuttings & then planting without any disruption to the roots. To use, simply place coir pellet in a tray of water (or seaweed solution) & leave for a couple of minutes until fully expanded.

For coconut coir pellets, plant no more than 2 seeds per pellet for small seeds and only one per pellet for larger seeds. If both seeds germinate, do not pull one out. Pinch off one of the seedlings at the base to remove. This will give the remaining seedling a chance to survive and thrive.

Actually regardless of medium, plants have all the energy they need for the first 2 weeks (sometimes more). Besides tap water (290 ppm) I don’t feed any nutes for the first 2 weeks or until I see the first sign of yellowing. Coco doesn’t have nutes in it, but ph 6 tap water should be all you need for the first 2 weeks.
