Re: Stealth Hydroponics Deep Water Culture Growing Q & A
My Definition of Deep Water Culture in Easy to Understand Language (Slang)
Over 2500 years ago, around 600 BC the Hanging Gardens of Babylon were built. That was probably the FIRST Hydroponic growing ever done. Roots dangled in FLOWING, moving water and for the next 2500 years, man thought to grow in Hydroponics, (in water) you had to have moving flowing water. As recently as 40 years ago, Hydroponics was done mostly in rain gutter type containers, with water being pumped from one end to the other, through the roots, creating flowing water.
The popularity of fish aquariums and the invention of plastic and glass changed all of that. Man figured out the water did not have to be moving or flowing, IF it was highly oxygenated water, ie add a air pump, some air stones and make bubbles. Thus,the DWC, Deep Water Culture of roots dangling in water with air added to the water.
Then came Ebb and Flow, Aeroponics, etc and all kinds of moderations on DWC.
DWC SYSTEM Enhancements
A more modern system is the DRIP SYSTEM where a stream of water, a flow of water or a DRIP of water is delivered to each root base, or grow cup. Until a few years ago, If it was a constant stream and flow of water, it had to be delivered on a TIMER, in Increments of watering, allowing the roots to get an air bath in between flows of water, or the roots would drown and rot. Then it was learned you could just DRIP the water and let it drip 24/7, if in drops, or put that on a timer too.
A dude in Michigan, a friend of mine from Australia, Martin Wiggett, started or created Deep Water Culture, ( he registered and trademarked the word) a sort of a DRIP and FLOW combined, but it is NOT a FLOW or STREAM of solid water, but a very slight trickle of half water and half bubbles or air, so the roots get a mix of both water, air and nutes to the root base, creating a way to start seeds in the cups and grow from seed more rapidly than any hydro system can deliver. We often see the word Deep Water Culture used as slang for a DWC with bubbling air stones, but it is not exactly the same.
Deep Water Culture uses a submersive water pump, that pumps water to an Irrigation Hub, also called an Irrigation Manifold, that divides the water into 6 streams, one to each grow cup and root base. It is the MOST rapid growing system available that I can find. I can get an average of one inch growth in height daily using the Bubleponics System in the Vegging Cycle. Yes, we actually have to raise the lights daily, everyday, to allow for new growth!
