Frequently Asked Questions (FAQ)
Why is it important to measure the climate at the canopy level?
The temperature and humidity near the floor and ceiling of a grow box differ significantly. For a plant's health and yield, the conditions around its leaves and flowers are what truly matter, not those at the base of the box.
Do I need to buy a hygrometer separately?
No, it is already included in the package. You receive a complete, ready-to-use solution right out of the box.
Will the holder fit my grow box?
We offer the 4 most popular sizes, which fit 99% of grow boxes on the market. The best way to be sure is to simply measure the diameter of your pole with a ruler before ordering.
