Octopots feed plants at the roots. The Hydro Wick holds the majority of the growing media above the water level preventing saturation.
Only the cup of the Hydro Wick is immersed in water. Water moves upwards into the growing media by capillary action.
Capillary action makes water and nutrients flowing between soil particles available to plant roots.
Air flow and the physical properties of the growing media are vital to efficient capillary action.
Octopots create the correct environment for efficient capillary action.
Octopot’s Gro Sleeve aerates the growing media like an air pruning pot or a root pruning pot increasing air flow.
Octopots growing media is well aerated allowing nutrients and water to easily flow between the soil particles.
Octopots require a 60/40 blend of high quality well-aerated growing media and perlite, specifically 60% soilless mix (peat based or coco coir) with no less than 40% Perlite.

Octopots design improves capillary action, transpiration and plant growth.
Transpiration is the process that provides plants with nutrients, water, evaporative cooling, and carbon dioxide entry.
The benefit of efficient capillary action and transpiration is increased uptake.
Plants that have constant access to water, nutrients and oxygen grow faster and produce higher quality yields.
Capillary action creates a moisture gradient throughout the growing media.
Octopots moisture gradient triggers a plant process called hydrotropism.
Young plant roots follow higher levels of moisture until they reach the Hydro Reservoir. Top watering is detrimental to root development and confuses roots.
Octopots subirrigation design keeps seeds, clones and cuttings well hydrated as they develop into the Hydro Reservoir.
The signal for root growth is varying water potential in a plant’s soil environment; the response is differential growth towards higher water potentials. Plants sense water potential gradients in their root cap and bend in the midsection of the root towards that signal. In this way, plants can identify where to go in order to get water.
As young terrestrial plant roots leave the soil to enter the water in Octopot’s Hydro Reservoir they undergo morphological changes to become hydroponic roots.
Octopots create a micro-climate that allows plant roots to make the morphological changes necessary for abundant life in a hydroponic environment.
This micro-climate exposes root tissue to darkness and high humidity levels causing Root Hybridization. Root cells differentiate and mature into specialized cells.
The dual root zone design is exclusive to Octopot Grow Systems.
Root hybridization triggered by the Octopot design creates plant roots with two different orientations. In other words, a "hybrid".
Octopot is the first company to commercially utilize the root transformation concept so we call it Octopotification™.
The size and structure of a plant’s hydroponic root zone is specific to the plant’s species.
For example, plants that require dryer conditions may send down fewer roots into the Hydro Reservoir than a moisture loving plant that may fill it with root mass.
Octopot’s hybrid design oxygenates plants without air stones. In general, oxygen is attracted to water. The primary mode of oxygen transfer into water is surface transfer of gases.
Octopots are designed with an expanded surface area of water in the Hydro Reservoir to trigger natural atmospheric exchange.
Octopot Grow Systems create an oxygen rich environment where dissolved oxygen is added to and removed from the system by natural atmospheric exchange (aeration and degassing).
Dissolved oxygen present in the water of Octopot’s Hydro Reservoir reflects a balance between oxygen producing processes (e.g. photosynthesis) and oxygen consuming processes (e.g. aerobic respiration).
dissolved oxygen and ph
Using air stones with Octopots is not necessary and may cause problems. Moving too much air through the nutrient water solution in the Hydro Reservoir can cause wide pH swings and lower levels of Dissolved Oxygen [DO].
This process is called dissociation. Water can hold only so much gas and dissolved solids total. Pumping air, especially CO2 enriched air, forms carbonates with elements in the water. These carbonates accumulate and lower the solutions pH. Water holds on to CO2, and some other gases, better than O2. As air moves through the water, O2 is bumped and CO2 attaches. DO is released from the solution and its level goes lower and lower over time.
Moderate pH swings in either DWC systems, Ebb and Flow hydroponic systems or soil pots can cause plant damage but moderate pH swings in Octopot's Hybrid System are normal and allow nutrients to be taken up at their optimum availability.
