Having the right environment is critical for your garden. Key elements to a successful garden room include relative humidity, temperature, CO2 (Carbon Dioxide) and air circulation/exchange. The ideal humidity for a garden room falls between 40 & 60 percent.
Temperatures in your grow room should be between 68-75 F degrees. Avoid drastic temperature changes over a short time period.
The water you use for your plants will determine how well your plants will grow, regardless of what you add in terms of nutrients and supplements. PPM (parts per million) or EC (electrical conductivity) are the measurement of the salts in a solution. You can reduce the PPM of your water using a Reverse Osmosis Unit, then build your nutrient solution around what your plants need.
Potential Hydrogen (pH) measures the acidity or alkalinity of your solution on a scale of 0 - 14. A solution is considered neutral at 7, acidic below 7, and alkaline above 7.
Nutrients come in organic and synthetic varieties and are available in both liquid and dry form. Nutrients can be separated into two categories, macro and micro nutrients.
Lighting is another key factor in obtaining optimal growth from your garden. Read more about lighting here.
