Grow Room Heaters
Keeping the temperature of your grow room within the correct range will go a long way towards helping to optimise your plant growth. The ideal air temperature range is between 18C - 25C (65F - 77F) with an average temperature over the course of a 24 hour period being between 21C - 23C (70F - 75F). A grow room heater will help your grow going sweetly during the winter months. Temperatures and relative humidity levels together create an effect called Vapour Pressure Deficit (VPD) For perfect grow temperatures and humidity levels (and therefore VPD), check out the Opticlimate Full Climate Control Units which can keep your grow room environment exactly right, no matter what the weather.
