Should I grow weed using coco fiber or rock wool?

Instead of using soil as a medium to hold the roots of your medical marijuana plants, you can use an inert medium — something that does not have the quality problems found with ordinary soil — something like coco fiber or rock wool.

Advantages:

• Almost as easy as growing marijuana in plain soil.
• Better yields than soil.
• Almost as cheap and simple as plain soil.
• The process is generally cleaner with fewer bugs and mess..

Disadvantages:

• Requires special fertilizers which are more expensive.
• Requires the purchase of coco fiber. This is not very expensive, but you may have to find a local store that stocks it.
