[Light] [Air] [Water] [Grow Matrix / Medium] [Nutrients]
++Water, Humidity (water vapor), and pH ++
Check the pH of your water and nutrients, and if soil needs more water, before watering~!
+++++
High end pH meters are $300 - 1000
You need these to check your water and nutrient mixes.

How much should you water cannabis?
- Stage of growth
- Size of container
- Outside temps and light intensity
- Health of cannabis plants -Drooping, weak plants; Yellow or brown leaves
- Check soil!
- Don’t leave your plants sitting in runoff
- Important to check pH when watering plants
Water well, but not too often!
+++++
WELL WATER / GROUND WATER with HIGH Hydrogen Sulfide is a key component to great plants!
When water drains through the plant, oxygen gets sucked down into the soil!

In City Water, Chlorine can be dissolved with Hydrogen Peroxide,
and Chloramine can be dissolved by Citric Acid ...
you can outgas the Chlorine Gas (Cl2) over time and with aeration pumps,
and Chloramine can be dissolved by Citric Acid ...
you can outgas the Chlorine Gas (Cl2) over time and with aeration pumps,
filter water to 30 ppm or lower.
[Chloride Ions (-Cl) are used in both plants and animal metabolism.]

If you have ever tried to humidify a grow room, ie add water vapor, when plants are smaller and light intensity is bright with air conditioners cycling, you’ll know it can be near impossible to keep up with traditional humidifiers (that are designed for spaces with low to minimal air exchange).
The amount of water vapor in the air surrounding the plant’s leaves plays a strong role in regulating the plant’s potential rate of photosynthetic activity–this is what VPD (vapor pressure deficit) is all about. When out of the sweet spot, crops suffer, and can easily be overworked to the point of stress or damage if humidity levels fall too low. Conversely, an overabundance of humidity will stifle growth rates, causing stretchy and weak growth that is prone to problems.
Traditionally, the indoor growers’ focus has been on delivering strong light, adequate mineral nutrition, good air movement, etc. VPD humidity control may be a secondary concern at best, sometimes with growers not realizing that their lack of attention to targeted humidity levels may be the source of problems that are preventing them from reaching their target or forecasted yields.
Besides often being ineffective in meeting the demand to humidify dry grow room air, traditional humidifiers can become a source of pathogens for crops, as biofilms, bacteria and fungi may develop in humidification pads, reservoirs, or in stagnant water that occurs when the system isn’t cycling, for example during grow room dark hours.
Steam-based humidification systems are energy-intensive and add heat load,
requiring additional cooling power.
Relative humidity (RH) levels influence a plant’s ability to transpire water and gases into the growing environment. When RH levels are low, growth rates slow, leaves yellow or wilt and signs of root rot will occur. Increasing humidity levels when cultivating is essential to success.
A Commercial Humidification System is the ideal tool for boosting Relative Humidity and optimizing VPD.
==================
A vertical farming scenario, either by grow towers or shelf levels, could use ram pump, which require no outside source of power other than the kinetic energy of flowing water from a head under high pressure due to the volume of the source tank.
Move an ionic liquid solution to a height and gather a large volume... then release that volume down the flow generator incline, which holds a magnet and metal.
This is akin to a turbine moving only the electricity is being generated without any mechanical movements or flow interference. The energy generated could be stored in a battery via a charge controller.
