2 Gallon Open Top Coco Bag for Full Flower Runs
Flower rooms that want to finish plants without a mid-cycle transplant often settle on a two-gallon container. This one arrives pre-filled with coco and open at the top, ready for a drip stake and a rooted plant or block. Coco pith, chips and fibers are blended to 56% water holding capacity with 38% air porosity. That mix keeps a reserve between shots while leaving enough air space that roots never sit saturated. The larger root volume buffers the plant through a long light period, so drybacks happen more slowly and each irrigation is easier to control. Rooms steering for flower can stretch the gap between the last shot and lights-off without the media crashing dry. The coir is washed five times, it is OMRI certified, and each batch comes with a certificate of analysis. A half pallet holds 924 bags, enough to set a full flowering room from one delivery. Soak every bag with pH-adjusted water, let it drain, and check runoff EC and pH on a few bags before the first full feed. Pre-drilled holes take drip stakes, and many growers run two emitters per bag at this size as plants drink harder late in flower. Tall flowering plants need support early. Trellis or stake before the stretch, because a soft-sided bag does not anchor a heavy plant the way a rigid pot does.
Running 2 Gallon Coco Bags From Transplant to Harvest
These 2 gallon coco bags fit medium-density flower tables where each plant runs a single cycle from transplant to harvest. That root volume holds up through the stretch and the final weeks of bulking without a step-up. Rockwool blocks sit straight on the open top, so plants rooted in cubes move over without disturbing the root ball. Coco brings almost no nutrition of its own, so feed from the first irrigation and keep calcium and magnesium in the mix. Matching containers across a room mean every plant dries back on the same clock, which keeps one irrigation program in charge of the whole canopy. A net inside the base holds loose coir in the bag, so trays and drain lines stay clear through the run. Raise the bags on a drain rail or slotted tray so runoff never pools underneath them. A half pallet lands as one heavy load, so clear floor space and keep a pallet jack ready. The bag is fully biodegradable, so the whole container and its coir can go to compost after harvest. Reusing the coir in a production room is a gamble, since roots and salts from one run carry into the next.
Key Features
- 56% WHC with 38% air porosity: A balanced coco structure that holds water between shots and keeps roots supplied with air.
- Three-fraction coco blend: Pith, chips and fibers keep the media open through a full flower cycle in a larger bag.
- Washed five times: Loose salts and fines come out before bagging, so the first feed starts closer to target.
- OMRI certified, COA per batch: Certification plus a batch certificate of analysis supports compliance records for every load.
- Drip-ready bag: Pre-drilled stake holes let one or two emitters seat in the same place on every plant.
- Internal bottom net: Keeps coir from washing out of the base and building up in trays and drains.
- Half pallet of 924 bags: A single delivery sets an entire flower room with identical containers.
- Biodegradable container: The whole bag composts with the spent coir after harvest.

FAQs
What does a 56% WHC and 38% air porosity rating tell me?
About 56% of the media's volume holds water after the bag drains, and about 38% stays filled with air. That mix carries a flowering plant between irrigations while keeping oxygen around the roots.
Is the coco blend OMRI certified?
Yes, Grow Junky coco is OMRI certified, and each batch ships with a certificate of analysis. That makes it straightforward to document the media in a compliance file.
How many 2 gallon bags come on a half pallet?
A half pallet carries 924 two-gallon bags. That covers a full flowering room in most commercial layouts from a single delivery.
How do I prepare the bags before transplanting?
The coir is washed five times before bagging, so preparation is mostly hydration. Soak each bag with pH-adjusted water, let it drain, and read runoff EC and pH on a few bags before the first full feed.
Should I use one or two drip emitters per bag?
Two emitters spread water more evenly through a container this size, especially late in flower when plants drink the most. The pre-drilled stake holes keep emitter placement identical on every bag.
Can plants rooted in rockwool go into these bags?
Yes, a rockwool cube or block sits straight on the open top. Roots grow down into the coir and the plant never leaves its cube, so the move is gentle on the root ball.
Is the 2 gallon size enough to finish a plant in flower?
For medium-density flower tables, yes, as long as irrigation keeps pace with the plant through the stretch and bulking. Trellis or stakes help, because a soft-sided bag gives a heavy plant less anchoring than a rigid pot.
Can the bags be composted after harvest?
Yes, the bag is 100% biodegradable, so container and coir can be composted together. Reusing the coir for another production run can carry root disease and salt build-up forward.
