Hydroponic weed is the method of growing weed such that each plant grows in a flow or bath of water that is heavily oxygenated and highly enriched with beneficial nutrients . No soil is used in this process, and instead, the plant grows in a sterile, inert growing medium.
All of the nutrients required for the weed to grow are mixed in a solution in the water in which the growth process takes place. This unique method of growing plants took birth over a century ago when it was created by William Frederick Gericke.
Although initially it was meant for just vegetables and garden plants, it was soon realized that this is a smart method of growing weed / marijuana.
Growing Weed Using Hydroponics
The word “hydroponics” is derived from Latin that literally translates to “water working”.
The plants take in their required nutrition both from the water and the air, therefore, it’s necessary to maintain a perfect atmosphere in your hydroponic system.
In a hydroponic system, the plants don’t need to expend energy growing big root webs to absorb the nutrients. This is because they are set up so that they are able to consume all the nutrients directly.
TG: Legal and illegal cannabis grows are expanding in the Mojave Desert region. We’ve heard from local officials that there’s been a dramatic increase in production in San Bernardino County, where cannabis cultivation is prohibited, and there are concerns over increased water withdrawals from stressed aquifers. The situation is very different in neighboring Riverside County, where it’s authorized. In many counties it’s still illegal to grow, but without a program that establishes civil penalties for unpermitted cultivation, these counties paradoxically don’t have many tools to stem illegal operations on private lands. If a grow operation is legal, the water source will be legal (and managed). For illegal grows, it is not clear where water is coming from.
What is the extent of cannabis cultivation in California?
VB: Consumers who buy legal cannabis sourced from a permitted outdoor farm can feel confident that it has met stringent environmental requirements.
VB: One benefit of legalization is the research we’re now able to do. Most of the things we talked about today we didn’t know at all five years ago. In five more years, we’ll learn a lot more.
What’s being done to manage water use in California’s deserts?
TG: Water quality impacts from pesticides and nutrients are a major concern. But, so far, studies haven’t detected high levels of contaminants in streams, and the effects from cultivation appear to be fairly localized. Water quality may be at risk, however.
How do illegal grows contribute to water quality problems?
TG: Cannabis regulations are oriented toward reducing water use impacts—including restrictions on when growers can divert from streams and requirements to use onsite storage if they rely on surface water sources. However, unpermitted farms don’t necessarily follow these practices.
We are concerned about cannabis water use because many cannabis farms are in remote upper watersheds that support sensitive species. There’s naturally low water availability in these headwaters, especially in the dry season, so even small diversions can have an impact on the ecosystem.
Note how often you water plants and write it down in a log. Get your marijuana plants on a watering schedule—as they grow out of the seedling stage, watering every two to three days is ideal.
A flush can also be done to clear plants of nutrients if they have a nutrient imbalance, such as nutrient lockout, when your plants are overloaded with nutrients and unable to absorb new ones.
How much should you water marijuana plants?
When growing weed outdoors, you’ll need to water more often as the weather gets hotter and less often as it cools.
Like all plants, cannabis requires water in order to perform its basic functions. Water helps plants absorb nutrients from the soil and then moves up the plant and into the leaves, and without it, the plant can’t survive. But giving a marijuana plant the proper amount of water may be more difficult than you think.
Flushing marijuana plants before harvest
There isn’t an exact science for watering a weed plant. You can’t observe the roots in most cases to see if they need water. Also, a plant is constantly growing and the climate it’s in will fluctuate, so the amount of water it needs constantly changes.
