Long Pot Square 0.85L – Space-Saving Elongated Planter for Clones & SOG

Maximize every square inch of your indoor grow tent with the Long Pot Square 0.85L, an elongated planter specifically designed to pack more clones into less space and accelerate your harvest cycle. This compact container forces roots to grow deep rather than wide, making it the ultimate tool for Sea of Green (SOG) setups and early seed germination while saving you a massive amount of substrate.

Setting up a high-density clone run can feel overwhelming when you aren't sure how to organize your space or which containers will give your young plants the best start. Many growers struggle to find the right balance, ending up with overcrowded canopies, tangled roots, or wasted soil because they chose standard wide pots instead of containers tailored for vertical root development.

When you lack a clear strategy and use the wrong pot size, the consequences hit your yield and your wallet hard. You end up wasting expensive premium soil on tiny cuttings that can't absorb the nutrients, leading to overwatering, root rot, and a frustratingly slow vegetative phase that makes you think your genetics are weak when the real issue is just poor root management.

The Long Pot Square 0.85L eliminates this guesswork by offering a streamlined, phase-based approach to high-density growing. By following a clear, step-by-step flow with these elongated pots, you can easily set up a flawless SOG canopy, optimize your substrate usage, and guide your clones from rooting to transplant with absolute precision.

Phase 1: Preparing your grow space and materials

Before you start filling your new containers, it is crucial to prep your environment and calculate your spatial needs. Since these pots measure 14.6 x 8.9 cm, you can fit a massive number of them in a standard grow tray, making them perfect for maximizing your indoor footprint. Take a moment to plan your layout and ensure your climate control is dialed in for young, sensitive plants. Here is what you need to check before getting your hands dirty:

• Measure your grow area to calculate exactly how many 0.85L pots will fit perfectly without crushing the foliage.
• Prepare a light, airy substrate mix (adding extra perlite helps) to encourage rapid root expansion in the elongated space.
• Ensure your grow tents are thoroughly cleaned and sterilized to prevent early fungal issues.
• Check that your rooting hormones and cloning gels are ready for action.

Phase 2: Filling and arranging the Long Pot Square 0.85L

Getting your pots ready is all about creating the perfect micro-environment for those fragile new roots. Because the Long Pot Square 0.85L is deep and narrow, how you pack the soil matters immensely for proper drainage and oxygenation.

1. Place a small layer of expanded clay pebbles or perlite at the very bottom of the pot to guarantee flawless drainage.
2. Fill the pot with your chosen substrate up to about one centimeter below the rim, avoiding packing it down too tightly.
3. Water the soil lightly with a mild root stimulator solution before introducing the plant, ensuring the medium is moist but not soaked.
4. Arrange the pots neatly inside your grow trays, making sure they sit flat and stable.

Phase 3: Planting and managing your clones step by step

1. Make a small, deep hole in the center of the moist substrate using a dibber or your finger.
2. Gently insert your rooted clone or germinated seed, ensuring the delicate taproot points straight down into the elongated space.
3. Lightly press the soil around the stem to provide stability without suffocating the root zone.
4. Place your pots under appropriate grow lights, keeping the intensity low initially to avoid stressing the young plants.
5. Monitor the moisture levels daily; the deep design retains moisture well at the bottom, so lift the pots to check their weight before watering.
6. Watch for vibrant, upward-reaching leaves, which is the ultimate sign that the roots are successfully diving deep into the pot.
7. Avoid overwatering at all costs, as the narrow shape can trap stagnant water if you drown the substrate.

Phase 4: Transplanting, cleaning, and future cycles

Once your plants have developed a solid, bright white root mass that reaches the bottom of the pot, it is time to transplant them into their final containers or flip them straight to flower if you are running a micro-SOG. The smooth interior of the Long Pot Square 0.85L allows the root ball to slide out effortlessly, minimizing transplant shock and keeping your plants growing vigorously.

After emptying the pots, maintenance is a breeze. Simply wash them out with warm water and a mild sterilizing solution to remove any leftover salts or organic matter. Letting them air dry completely ensures no pathogens survive to ruin your next batch of premium genetics.

For your next run, take note of how quickly the roots reached the bottom. Adjusting your vegetative time based on these observations will help you dial in the absolute perfect schedule, saving you even more time and maximizing your yearly harvests.

Advantages of following this structured SOG method

• More consistency across your entire canopy, ensuring an even light spread.
• Fewer silly mistakes like over-potting tiny clones in massive containers.
• More control over your vegetative timing and root development.
• Massive savings on expensive soils and premium substrates.
• A true feeling of mastering the Sea of Green technique like a pro.

Frequently Asked Questions about the Long Pot Square 0.85L

How many of these 0.85L pots can I fit in a square meter?

Thanks to their compact 14.6 x 8.9 cm dimensions, you can comfortably fit over 70 of these pots in a single square meter, making them the absolute best choice for high-density Sea of Green (SOG) setups.

Are these pots suitable for germinating seeds?

Absolutely. The elongated shape is perfect for the initial taproot of a freshly germinated seed, allowing it to grow straight down and establish a strong foundation before you transplant it to a larger container.

Do I need to add extra drainage holes?

No, the Long Pot Square 0.85L comes with an optimized drainage design at the base to ensure excess water escapes easily, preventing root rot and keeping your substrate perfectly aerated.

How long should I keep my clones in this pot size?

It depends on your strategy. If you are transplanting, usually 1 to 2 weeks is enough for the roots to fill the pot. If you are doing a fast SOG, you can flower them directly in these pots after a very short vegetative phase.

Personal Experience of Pevgrow’s CEO (Alan)

When I first started experimenting with Sea of Green setups, I made the classic rookie mistake of using standard round pots. I was wasting so much space and soil, and my canopy was an absolute mess. Switching to these elongated 0.85L square pots completely changed the game for me. I organize my phases strictly now: I prep my trays, load up the pots with a light coco mix, and drop my rooted cuttings straight in. The way the roots shoot straight down instead of circling the top is incredible to watch.

I remember overwatering them during my first run because I didn't realize how well the deep design retains moisture at the bottom. Once I learned to lift the pots and check their weight before feeding, my root zones exploded with healthy, fuzzy white growth. Now, whether I'm pheno-hunting or just doing a quick turnaround clone run, these pots are my absolute go-to for the early stages. They save me money on substrate and make transplanting smoother than ever.
