You might have heard about the benefits of growing marijuana in coco coir, but are not sure if it is right for you. Since growing in coco coir is relatively new, you may not have even heard of it. This article is intended as a basic guide to growing marijuana in coco coir, and it is an excellent way for beginners to gain some experience before moving on to more complicated growing methods.

A Beginner’s Guide to Growing Marijuana in Coco Coir

Coco coir is, quite simply, the fibers from processed coconut shells. If you have ever seen a coconut at the grocery store, you have noticed the brown hairy outer shell. The coco coir is made from these fibers. This is a great growing medium because it is relatively inexpensive and is totally renewable. Also, it is very easy!

In order to get started growing marijuana in coco coir, you first need to get some basic equipment.

  1. Pots for planting the seeds or clones in. For a first grow, two or three plants are ideal.
  2. Coco coir
  3. Perlite (for drainage)
  4. CFL lights, two 40 watt bulbs per plant
  5. A timer
  6. Nutrients for hydroponic gardening
  7. A pH testing kit
  8. Marijuana seeds or clones

As you can see, the list of equipment is quite small compared to different growing mediums. The best thing about all of them is that other than the marijuana seeds or clones, they are widely available in an any garden center that has a section for hydroponic gardeners. All of the items can also be purchased online for a reasonable price.

Once you have all of the needed equipment, you can begin the growing process. First, cover the bottom of the pots with a thin layer of the perlite. This helps keep the plants drained. Then, fill the pots with the coco cair and water them completely. Once you see the water draining out of the bottom of the pots, the cocoa is wet enough.

Place the marijuana seeds or clones in the coco coir and press down firmly. Then, set your lights up so they are about four inches from the tops of the pots. You will not need to water the plants the first day, but you should test for dryness every day anyway.

When it comes to feeding your marijuana seeds or clones, it is best to start out feeding only about a quarter of the amount your packaging calls for, at least for the first week or so. This gives the plants a chance to adjust to the nutrients. Also, do not feed the plants every time you water. Usually every other watering is sufficient. This feeding/watering schedule will carry you through the first weeks of your planting.

When you water, whether with or without the nutrients, you want to make sure you check the pH level every time. For coco coir growing mediums, a pH range of 5.5-6.5 is best. Too much over or too much under these levels can cause problems that are easily avoided.
