Pulse One

Worth every penny

So far I am loving my Pulse One. It gives me so much useful information at my fingertips. I would absolutely recommend this product for the serious hobbyist grower.

Pulse Averages

The Universal language is math. Therefore everything is numbers. I have 5 Pulse one sensors in my grow. They are installed in every corner of the room and one in the center. This will reveal all the different microclimates in my environment., Positioning of lights, fans, dehumidifiers, humidifiers, and air conditioning will cause different microclimates in every grow room. The Pulse one sensors allow me to figure out what my daily microclimates are in each section of the room. Simply add all the readings of each sensor according to temperature, humidity, and vpd then divide that number by how many total sensors you have and this will give you your averages. Let's not forget the three important phases that the plant goes through in its life cycle. Stretch phase, bulk phase, and ripening phase. Which all require different climate steering according to each phase. What I personally like about the pulse app is If I make a climate adjustment day or night I can determine what changes took place within the hour, 3 hours, 12 hours, or a full day. Remember we cannot crop steer irrigation without climate steering. They both go hand in hand.Thank you guys @ Pulse for this wonderful tool.
