ALT Air Layer Technique is a Deep Water Culture Hybrid.
Flooding and partially draining the water to the level of the plant, the Biogarden behaves like a bay, nourishing and hydrating roots when the level rises.
When the level drops and roots are exposed, the air layer oxygenates the roots and supports a biological ecosystem to help with filtration. Water flows continuously during the flow cycle and never fully drains during ebb cycle.
This cycling makes it possible for plants to become their own biofilter unit, with aerobic microbes binding to the roots, consuming organics that are part of the nutritious cycle for plant growth. The results speak for themselves.
ALT Technique within Biogarden
Features and benefits with ALT
- Nutrients easily distributed
- Stationary trays for plants creates air layer
- Aerate with little energy
- Supports more organic elements
- Root zone -feeds rhizome bacteria
- More dense growth
- Easier seeding, easier harvest
One way the Biogarden achieves sustaiability is by improving efficiency of energy power.
The need for mechanical aeration is eliminated using Bioponica’s growing method we refer to as the “ALT Air Layer Technique”. It is a means of growing plants on the surface of the water. Different from the others, yet similar; ALT is a hybrid of DWC – deep water culture, NFT nutrient film technique and ebb and flow.
