Gardening indoors brings all the joys of a garden indoors, but some of the headaches come too. Plants are known for breathing CO2 and discharging O2, but most people just look forward to the fresh produce that these plants provide. Those of us with limited garden space may already use containers and raised beds to facilitate the root space we cherish so much. Windows and fluorescent light are a great start when looking into indoor gardening, but to facilitate the same growth rates that we see outside we are gonna need bigger lights. Those gardeners looks to prepare or preserve their garden indoors will certainly want to take advantage of the low cost and low heat of fluorescent light as well as a floor fan to help generate air flow around the foliage of the plans. Once plants are ready to introduced outside and acclimation period must be given to allow the plant to prepare it self for the harsh rays of the sun. For those of us without the antiquity space to plant outside, we must utilize the space, energy and growing medium that will help us produce the same quality fruit and flower we get outside but in a synthetic and controlled environment.
Most gardeners start out in a closet but very quickly realize the ventilation can be difficult in a confined space and most closets do not have wall plugs in them. To remedy this, most gardeners will purchase a tent or indoor greenhouse where they can not only ventilate the air but they can place the tent or greenhouse where ever it is most convenient to have the power need to run the lights and fans that will keep our plants growing and happy.
Most gardeners start out with only one space and this will work for most, but for those wanting to hold on to genetics or flower year round this is not enough space to root cutting as well as maintain an area that had a light cycle which keeps the plants in their vegetative state.
High Intensity Discharge are the most common lights you will find in the horticulture world and the majority of growers use 1000W HPS (High Pressure Sodium) lights because they are some of the largest wattage’s available and because they cover the most room with a single light. Fluorescence’s and LED’s are making their way to being more and more efficient but the testing and development has not come far enough yet to permit them to replace HIS lighting in the larger greenhouse and commercial applications.
Plants use photosynthesis to generate carbohydrates and carbon into energy which they process nutrients, water and, air with. These factors build up everything the plant likes and they all start with the lighting. These factors will influence and dictate a majority of the other factors, such as, if you are using low lights, such as, a fluorescent light, then you can lower the food levels as well, this is also true vice-versa, if your light is strong your nutrients can typically be stronger as well.
Temperature & Humidity
“Keep it as bright as possible, while keeping it as cool as possible.” -A. Grower
This is the best advice i have ever come across, the best answer for what temperature should you keep a grow room is simple. Keep it as cool as possible with your light all the way on. If this means a new air conditioner then so be it, but the last thing any grower wants to do is turn down the lights, or even worse, replace them with lower wattage’s. Temperatures in a grow room should never exceed 85°F, and ideally your range would be between 65°F – 75°F, but nothing in this world is perfect so that’s why i call it a range. Most hygrometers have a “Max/Min” function where you can see the higher and lowest levels in which the hygrometer read. These meters also read humity, these levels should never exceed 80% and ideally would stay between 50%-60%, in fact some vegetative rooms run on the higher side of humidity as it seems to encourage foliage growth in some plants.
Once these parameters have been met and you can maintain these levels year round, you can feel confident that your garden will be just as fruitful as any garden outdoors. We are always testing and investigating new way to make our gardens more productive and more efficient, so if you ever have a grow room design or construction question feel free to call us six days a week from 10am – 6pm.
