1.) Gather all materials and place everything near your tub (or wherever you’re going to rehydrate to coco coir bricks)
4.) Maintain vegetative plants until they are half the final desired size.
1.) Germinate seeds in fresh Rapid Rooters on top of the moist but not soaking coco coir in your solo cups. Some growers will plant their seeds directly in the coco coir, and that works well, too. You can also place the Rapid Rooters in a tray, making sure there’s a very shallow pool of water at the bottom to keep them moist. Fresh Rapid Rooters give some of the best germination rates, but of course there’s other ways to start your plants.

Are you interested in growing cannabis with coco coir? Coco coir is a highly productive growing medium for cannabis that gives the experience of growing in soil, but many of the benefits of growing weed in hydro, including fewer bugs and faster growth.
5.) Wait 8-10 minutes or until the coco coir gets fully hydrated.
Coco fibre is also the term often used to refer to the general purpose grade of coco which is ideal for growing longer term crops under soilless cultivation. Worldwide coco is used for soilless crops such as tomatoes, peppers, cucumber, melons, aubergines, ornamentals, cut flowers and many others because the structure of the coco does not break down over the time frame these longer term crops are grown for. Thus high rates of root zone aeration and moisture retention are typical in both short and long term soilless crops and this results in high yields and good root health.

These days good quality coco has proven to be a superior growth substrate for a large number of different crops, with the advantage of being from a renewable and environmentally sound resource.
Different types of coco products – uses, pros and cons
figure 4: Coco is available in a range of grades from very coarse ‘orchid fibre’ seen here, to fine ‘coco dust’.
However while there are excellent brands of coco on the market, there are also still poor quality supplies still being sold as a growing medium and growers need to select and only use a reputable brand, preferably one which has an accompanying `coco nutrient’ formulation designed to work with the cation exchange properties of the product.
Tips and tricks when using coco
Coco was initially seen as a replacement for peat in greenhouse production – coco does not have the water repellence of dry peat, or the low pH values. However in the early days of experimentation with coco growing substrates many problems were found due to inconsistency of the product. Many coconut sources were retted in seawater and contaminated with very high levels of sodium and unpredictable levels of naturally occurring potassium.
There are many different types of coco products on the market. The husk of coconuts yields not only very coarse long fibres which are used to make a wide range of products such as rope, carpets, mats, brushes, basket liners and others, but between these coarse fibres is a corky substance called coir pith, coir dust, coco peat or coir peat. Many grades of horticultural coco exist and some have been specifically designed for different plants and systems. The very fine particle size of coir dust retains a high level of moisture and this is suited to seed raising and for smaller seedlings and plants. While a high moisture holding content in fine coco dust is an advantage in some situations, it can create problems with over saturation of the root zone. Grades of coco often used in slabs may consist of larger particles or `flakes’ of coco which allow a good degree of drainage and resist packing down over time as commonly occurs on substrates such as peat.
The proper way to pronounce coir in the U.S. is “coy-yer”. It’s a bit different in the U.K. If you want to hear a sound clip of how to pronounce coir, check out the coir pronunciation examples on this Cambridge Dictionary page.
And make sure to maintain the proper ph for growing weed in coco, around 5.8–6.0 range. Use a Ph meter. Don’t guess at it. Marijuana needs a slightly acidic medium in order to properly absorb nutrients, and improper Ph leads to the majority of issues that new growers face when using coco.
proper pH level for coco as well as maintaining the optimal PPMs for coco to avoid nutrient burn.
More experienced coco growers may invest in additional nice-to-haves like automatic watering timers and drip systems to reduce the amount of day-to-day work to maintain your plants.
How to pronounce coir
Coco offers the advantages of hydroponic growing: fast, vigorous root growth and plant development with precise control over nutrition.
For large plants with very long veg times, 7 gallon or 10 gallon fabric pots are needed for growing in coco.
Coco coir is a growing medium made from fibers from the husks of coconuts. Coco coir has a high lignin content that makes it longer-lasting, holds more water, and does not shrink off the sides of the pot when dry allowing for easier rewetting. Due to it’s ability to retain moisture it makes a great substrate for all types of plants, including our dear friend cannabis. Coco is an inexpensive growing medium and uses the natural byproduct of commercial coconut production, so it’s environmentally friendly.
What is coco coir made of?
One of the issues with buying weed grow supplies at Home Depot is their staff isn’t able to assist with grow questions, and they likely won’t know coco pest from peat moss. I’ve overheard employees there telling customers to consider using prebagged Miracle Grow for cannabis, which isn’t a good option. Miracle Grow is primarily composed of peat moss, and while its readily available at home depot it isn’t the equivalent to coco coir.
Advanced Nutrients Perfect Sensi Grow A+B is used for weed plants in vegetation. Advanced Nutrients Perfect Sensi Bloom A+B is used after you flip plants to flowering. You’ll need to get both sets in order to properly grow in coco coir.
