Keeping your growing room at an even temperature will ensure that your plants are helped with their transpiration – when they give off water vapour through their stomata. Poor air circulation can easily lead to damage to your crops so you need a reliable device to prevent this from happening. The Air Circulator (Available as 9, 12 or 18 Inch) will be able to do a great job for you. When you get the appropriate level of air circulation in your grow space you not only get that even room temperature, which you can set if you have automatic controls, but you can also help prevent mould spores from invading the space and settling on your plants. Keeping the atmosphere friendly to whatever you're growing allows your crops to thrive, be healthy, and provide you with long-lasting and high yields.
