Description
Coco, Mycorrhizae and a Pot in One Bag
The UGro Rhiza Quick Fill Grow Bag is a flexible, UV-treated growing bag holding a compressed block of buffered coco coir enriched with endomycorrhizae and natural Trichoderma. Add water and the block swells inside its own bag into ready-to-plant substrate – no separate pot and no heavy sacks of media to carry. The Pot4 expands to 4 litres of coco from 2–3 litres of water, and the larger Pot9 gives 9 litres from 5–6 litres. The maker's mix-of-three blend of 40% coco peat, 30% short fibres and 30% chips balances water and air for indoor and outdoor growing.
Key Benefits
- Medium and container in one – plant straight in; holes in the base drain the excess
- Mycorrhizae already in the mix – beneficial fungi extend the roots' reach for water and nutrient uptake
- Natural Trichoderma – a beneficial fungus that competes with root-rot organisms
- Buffered and low in salts – pH 5.5–6.5 and EC below 0.6 mS/cm for a clean start
- Holds water, stays airy – the peat, fibre and chip mix keeps moisture and air in balance around the roots
- Compact until used – store dry, hydrate only what you need; peat-free
Slow Root Establishment and Transplant Shock
Every move from pot to pot sets roots back. Planting straight into the bag that carries the plant to the end of its cycle removes a transplant, the mycorrhizae start working with the roots from day one, and the fibre and chips keep the root zone draining freely instead of sitting waterlogged.
How to Use
- Position first: stand the bag on a tray where it will stay and open the top
- Hydrate: pour in 2–3 litres of clean water for the Pot4 or 5–6 litres for the Pot9; a wetting agent helps it absorb evenly. Wait a few minutes for the block to expand, loosening it by hand if needed
- Check the run-off: read pH and EC before planting
- Plant: set a rooted cutting, plug or seedling directly into the coco
- Feed: use a coco nutrient at its maker's pH and EC, watering to a little run-off so salts do not build up
- Spacing: up to 49 Pot4 bags per square metre (7 × 7) or 25 Pot9 bags (5 × 5)

Frequently Asked Questions
What is the difference between UGro Rhiza and UGro Basic?
Both use the same buffered 40/30/30 coco blend. Rhiza has endomycorrhizae added to the coco; Basic is the plain buffered substrate without the added fungi.
Does the coco need rinsing or buffering first?
No. It is supplied buffered with an EC below 0.6 mS/cm, so it is ready to plant once hydrated. Check the run-off pH and EC before the first feed.
Can I run it on drip irrigation?
Yes. Stand the bag on a tray or saucer, put a dripper or drip ring into the top and let the punched holes in the base drain the excess.
