UGro Pot9 Professional Rhiza – Dehydrated Coconut Substrate 9L

UGro Pot9 Professional Rhiza 9L is not just a block of earth; it is a high-performance cultivation system designed to make your life easier and your plants huge. We are talking about a 900-gram dehydrated brick that, upon contact with water, transforms into 9 liters of high-quality coconut substrate, enriched with endomycorrhizae to take your root system to the next level.

Why your roots are begging for this substrate

Problem: We all know the hassle of hauling huge, heavy bags of soil up the stairs or trying to be discreet when setting up a crop. Furthermore, generic substrates often compact, suffocating the roots and causing slow growth or, worse, rot that ruins months of work.

Agitation: There is nothing more frustrating than seeing your plants stalled because the roots cannot breathe or absorb nutrients well. If the base fails, no matter how many expensive fertilizers you use, you will not get the buds you dream of. A weak root system equals a mediocre harvest.

Solution: The UGro Pot9 Professional Rhiza solves all this in one go. It is light, discreet, and comes with the perfect structure (coco peat, fibers, and chips) to ensure maximum aeration. Plus, the added mycorrhizae create a symbiotic network that multiplies the nutrient absorption capacity. It's like giving your plants a second stomach.

The smartest and most discreet way to grow

This product is designed for the modern grower who values efficiency. You don't need to buy separate pots; the packaging itself is a UV-treated grow bag with drainage holes. It is ideal for Urban Gardening where space and discretion are gold. You receive a small brick, hydrate it, and boom: you have a professional pot ready to host your best strains.

Key features and benefits in a nutshell

• Enriched with Endomycorrhizae: Fungi that colonize the roots, improving the absorption of water and nutrients for explosive growth.
• All-in-One Format: The wrapper is the pot. It includes drainage holes, saving you money and cleaning time.
• Perfect Aeration: The mix of peat, fibers, and chips prevents caking, ensuring oxygen always reaches the roots.
• Total Discretion: A 900g brick fits in a backpack. Say goodbye to the curious looks of neighbors seeing you carry 50L sacks.

How to use it in a few steps

You don't need to be an expert to get professional results with UGro Pot9. Follow this simple process:

1. Open and Position: Cut the top of the bag and place the block in a place where excess water can drain (a tray is ideal).
2. Hydrate: Slowly pour about 5 to 6 liters of quality water (preferably with adjusted pH) over the block.
3. Wait and Fluff: Let the coconut absorb the water and expand. Use your hands to fluff the substrate and ensure it is evenly hydrated.
4. Plant: Your pot is ready. Introduce your seed or cutting and start your cultivation cycle.

Frequently Asked Questions

Do I need to add nutrients from the beginning?

Yes. Coconut is an inert substrate, which means it has no nutrients. Although UGro comes buffered (treated with Calcium and Magnesium), you must add fertilizers to the irrigation water from the first week.

Can I reuse the substrate?

Technically yes, but to maintain the efficiency of the mycorrhizae and the structure, we recommend using a new block for each crop, especially if you want maximum yield.

Is it suitable for outdoors?

Absolutely. The bag is treated to resist UV rays, so it holds up perfectly under the sun during a complete cycle.

What is the advantage of chips in the mix?

The "chips" are larger pieces of coconut that create air pockets. This is vital so that the roots do not drown and grow thick and white.

Personal Experience of Pevgrow’s CEO (Alan)

I've always been a fan of coconut for the control it gives you over the plant's feeding, but the UGro Pot9 format is on another level of convenience. I usually recommend it to friends who are starting out and don't want to fill their house with plastic pots and huge bags of soil. You throw a couple of these bricks in the closet, and you have a setup ready for whenever you want to start.

What I notice most is the speed of the start. The mycorrhizae are not a myth; you can see how the plants grab onto the substrate much faster than in sterile coconut. If you combine this with a good root stimulator in the first irrigations, the vegetative growth is scary fast. For me, it is the best option for balconies or small indoor tents where every centimeter counts.
