RIOCOCO PCM Open Top Grow Bag | 2gal

Ready-to-Plant Coco Open Top Grow Bag, 2gal

Frequently Asked Questions

What is the coco chip to pith ratio?

60% coco chips to 40% coco pith. That ratio balances aeration with water-holding capacity in a pre-filled bag.

How soon can I plant into this bag?

Right away, this open top bag is ready to plant into directly. There's no additional blending or amending step before use.

What is the EC?

Less than 0.75 EC out of the bag. That low starting EC leaves room to build a nutrient program without correcting for residual salts first.

Does it contain fine dust particles?

No, it's blended without fine dust particles. That screening step is part of what keeps the medium's porosity consistent bag to bag.

What size grow bag should I choose?

RIOCOCO PCM Open Top Grow Bags come in 2gal, 3gal, and 5gal sizes, so growers can match bag size to container or crop. All three sizes use the same washed coco chip and pith blend.
