Environmental Control

Fresh air is a key to a successful indoor garden. When indoors you must bring in all that is present outdoors naturaly into the growroom, with good fresh air ventilation, fresh air is inexpensive and real easy to find. fresh air is one of the most overlooked factors. Experienced gardeners know the importance of fresh air and take alot of care to set up a proper air movement. The main three factors are, stomata,ventilation, and circulation. lets start with STOMATA which is  microscopic pores  located on the underside of the leaves. the stomata regulate the flow of gasses in and out of the plant. it is very inportant to have air movement to keep these pores clean and free of filmy residues, dust, pollen etc...... Next we have CIRCULATION if the air is still, plants tend to use up all the Co2 next to the leaf surface. Then a dead air space forms stifing the stomata, slowing growth. The air will also stratifies with warm air rising and colder air settling in the bottom of the room, and lets not forget how important air circulation is for prevention of insects and fungus, mold spores are present in all growrooms. Now last but not least we have VENTILATION,  On the average a 10' x 10' garden will use from 10 to 30 gallons of water per week. It transpires and evaporates into the air so gallons of water are held in the air. And if this moisture is left in the room, the leaves will get limp, transpiration and the stomata will be stifled. Remember the flow of water through the plant helps keep it erect. Successful indoor gardeners know that a vent fan is a important as water, light, heat, and fertilizer. In some instances it is more important.
