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.
If you have coco coir in brick form, make sure to purchase a high-quality brand. Every brick will be relatively uniform. When you add 4-5l of water and leave it to soak for about 30 minutes, a consistent 9-10l of medium will be produced from each brick. Simply add perlite and mix by hand in a good-sized bucket.
Without coco specific nutrients you will pretty soon discover, that coco coir doesn’t retain calcium very readily. Dialling in the nutrient solution can be tricky for beginners. More so with a mix and match of hydro nutrients and supplements. Iron is another missing micronutrient in coco coir that growers experience deficiencies with and often never resolve, thus reducing the final harvest. Start with the coco specific nutrients and you won’t have to troubleshoot later. Especially if you are a first-time grower.
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.
Coco coir unlike most soils for cannabis cultivation is unfertilsed. This is where hydro growers get to transfer their skill set. A light nutrient solution must be applied just like in a hydro crop from the beginning. The pH of your water will have to be adjusted to ensure you stay at the sweet spot for coco coir, namely a pH value of 6.0. In order to accurately keep the pH and nutrient solution dialled in, you have two options.
Growing cannabis in soil alone offers good results, but soil amendments such as peat moss and coco coir can make good results great. They add structure, hold water, improve acidity, and boost microbial life.
Once your seeds have grown into seedlings and outgrown their starter pots or plugs, transplant them into the peat moss mix.
Peat moss also makes a useful soil amendment. Also known as Sphagnum, peat moss is a genus of around 380 separate species of mosses. Peat moss works to acidify its environment by uptaking cations like magnesium and calcium, and in turn releasing hydrogen ions. By outputting hydrogen, peat moss slowly builds bog-like conditions that can reach deep into the ground. In nature, the mosses eventually form a peat bog.
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.
Your cannabis growing medium isn't just limited to soil. Learn to grow the herb using coco coir and peat moss mixes.
Some growers also like to mix coco coir with perlite and soil. Again, each will have their own ratios, but a good rule of thumb is roughly 10–20% coco, 30% perlite, and 50–60% soil.
Alternatively, you can use coco coir on its own (or a coco-perlite mix) as a soilless growing medium. Remember, if you do this, your plants won’t receive any nutrients from soil, so you’ll be reliant on using liquid nutrients.
Coco coir, sometimes just called coco or coir, is a natural fibre extracted from coconut husks (who would’ve guessed, right?) Besides being an awesome grow medium for all kinds of plants (cannabis included), you’ll also find this stuff in doormats, brushes, and mattresses. And while growing a plant in coco coir might seem super new, humans have actually been using coco for thousands of years. Historical texts show that Indian and Arabic sailors used coco to make ropes on their ships and rigs.
By the 19th century, the English had already set up a coir industry, mainly using the material to produce carpets and other types of floor coverings. By the 1980s, it had officially made its way into the gardening industry after being used commercially in Holland to grow roses and lilies. Today, you’ll find all kinds of things made of coir, including pots, baskets, rugs, and much more. One of the world’s biggest producers of coco coir is India. And, of course, you’ll find it at any decent garden center as a growing medium.
Pre-mixed coco blends: Pre-mixed coco blends can be bought from a garden center just like regular soil. They usually contain a mix of coco and either perlite, clay pebbles, or both. This is a great option if you don’t have the time or space to buy entire bricks and soak, rinse, and dry them at home. As always, opt for a high-quality mix. Your plants will thank you in the end.
Coco coir makes for a great potting medium and can be used on its own, or together with other substrates like regular soil and perlite. Coco coir is particularly popular among indoor growers, who love it for its ability to hold plenty of water while still offering great drainage and aeration. If you plan to use a coco coir mix, you have two options; you can buy ready-made mix from a regular garden centre, or you can make your own at home.
As always, you’ll want to rinse your coir to remove any excess salt. Coir tends to clump together when rinsing, so break it apart again to make sure it’s well-aerated. Then, proceed to pot your plants as you would normally. When using coco in a hydro setup, you’ll want to pay close attention to the nutrients you’re using. Remember, hydro plants take all their nutrients from water, and coco coir holds and distributes water very differently to regular soil.
If you choose to make your own, make sure to opt for quality coco bricks, preferably labeled as “low salt”. Once you’ve got your bricks, soak and dry them (as we mentioned above). Once the bricks are ready, you can start breaking them up and mixing them with your soil. The ratio of coco to soil is up to you, but most growers will use around 10–20% coco. Once you’ve finished mixing, you can also add a touch of compost or fertiliser to the mix to help make for a more nutrient-rich growing medium.
