Air is full of moving particles. As humidity increases, the amount of particles also increase. When temperatures rise, these particles become more active. The combination of the two will increase static pressure. This pressure will make it increasingly more difficult for your plants to breathe. This asphyxiation will increase until they suffocate at 55% humidity and 100ºF, or 70% humidity and 90ºF.

If the humidity in your garden is too high mold, mildew and other types of fungus can destroy your garden in a matter of weeks. Plants transpire water through tiny pores on the leafs called stomata. If the humidity is to high or low, photosynthesis will slow down. This decrease in photosynthetic activity effects the uptake of water and nutrients. Maintaining proper humidity levels is critical in order to keep your plants producing at their very best.

• Vegetating plants grow best in a 55% – 65% humid & 70º-75ºF environment
• Flowering plants grow best in a 35% – 45% humid & 68º-72ºF environment

Water Temperature

Water temperature is a huge factor in terms of plant health, cold water holds more oxygen molecules then warm water, roots need oxygen! For best results keep water temperature between 65° – 72°, and be sure to add lots of oxygen, this will prevent Pathogen’s from destroying your plants and allow them to grow faster.

Don’t Pick Too Early

Don’t pick your crop early! Time is money, the longer you wait the more valuable your crop becomes. If possible use a hand held microscope to examine trichromes. If that’s not an option, follow the seed company’s recommendation or even add
a week.
