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. The macronutrients are nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. The micronutrients or trace nutrients include iron, manganese, boron, zinc, copper, molybdenum and chlorine. If the nutrients are deficient or abundant you may see burning, yellowing, or curling. You do not want to over or under fertilize. Most fertilizers will have an N-P-K (Nitrogen, Phosphorus and Potassium) on the front of the bottle. In the vegetative phase the “N” will typically be higher. In the bloom phase the “P” will be higher. Potassium “K” is called the regulator of plants. Often called potash, potassium helps plants use water and resist drought. Potassium is important to food crops and enhances the size of fruits and vegetables. You may also consider adding supplements or additives into your nutrient mix. These additives can increase size, flavor, and aroma. When used together nutrients and supplements will help your garden reach its full potential.

High intensity discharge (HID) is the preferred lighting system for a garden room. The two types of HID lighting commonly used are HPS (High Pressure Sodium) and MH (Metal Halide). HPS lamps deliver more of an orange/red spectrum, which is ideal for most plants in the flowering/blooming stage. MH lamps deliver more of a blue/green spectrum, which is ideal for most plants in the vegetative/growth stage. Another type of lighting ideal for plant growth is T5 lighting. T5 lighting is a high-output fluorescent bulb with low heat and minimal energy consumption. It is an ideal light for cuttings, mother plants, and short growth cycles. Remember that all plants require light in order to grow and bloom. Most plants grow and bloom according to the amount of light they are given. In the growth or vegetative phase plants typically want 15-18 hours of light per day. In the bloom stage you reduce the amount of light the plants get to 10-12 hours per day. You want to make sure the light comes on and off at the same time each day (just like Mother Nature) the best way to do this is by having your lights on timers.
Having the right environment is critical for your garden. Key elements to a successful indoor garden room include relative humidity, temperature, CO2 (carbon dioxide) and air circulation. The ideal humidity for a garden room falls between 40% & 60%. Some plants like higher humidity, but know that higher humidity can lead to problems with fungus and disease. Temperatures in your grow room should be between 68 – 75 F degrees. Temperature changes will lead to variations in humidity levels. Avoid drastic temperature changes over a short period of time. Your plants also will need CO2 to grow quickly and robustly. Assuming you have good air circulation/ exchange, your garden room will have between 300-400 PPM (parts per million) of CO2; higher CO2 levels will accelerate growth rates up to 20%. If you choose not to supplement CO2 in your garden room, it is important to address the air circulation/exchange so that your plants will receive fresh CO2 constantly.
