Hydroponics refers to a specialized method of growing abundant healthy plants like cannabis without the use of traditional soil as a growth medium. Instead, hydro setups involve suspending plant roots within perfectly pH controlled aerated water integrated with dissolved mineral nutrient solutions. There are several different primary hydroponic system styles that can be employed including deep water culture, drip or irrigation systems, ebb and flow, nutrient film technique and aeroponics that all incorporate unique ways to automate water and nutrient delivery to the roots.
With no loose soil medium involved, the key variables of water pH, precise mineral nutrient levels, oxygenation, temperature control and circulation must be even more closely monitored and regulated within tight tolerances. While hydroponic systems demand greater initial investment and involvement to operate compared to growing in traditional soil or containers, the powerful control over the root zone environment allows for incredible growth rates and yields when properly optimized.
Most hydroponic reservoirs and systems recirculate drain water and actively refresh depleted nutrients, making this method incredibly efficient in terms of water usage and minimizing waste. Skilled hydroponic growers greatly praise the overall cleanliness, ease of access, and sheer plant growth potential unlocked by allowing cannabis roots constant exposure to their ideal aqueous conditions.
