Can anybody explain to me the VPD concept?
my garden is very cold during night 13.5ºC as the minimum, humidity goes up to 72%
During day it usually goes to 21ºC and 52%
I´m watering the plants every 3-4 days (when they ask for it) with 0.75L on 6L pots
Am I doing OK ?¿
In a nutshell, VPD is a calculation of how much moisture the air can hold at different temps. If your moisture goes higher, condensation occurs(dew) and if you go under the plants pull more moisture from the roots, aka require more water. Running a little dry is better than too moist outside of germination/cloning IMO. I personally only worry when I get too wet....if you feed heavy running dry can lead to nutrient issues though.
1st plant harvested, was flushed with water only this week.
the other one needs 1 or 2 weeks more but has more compact indica style, bigger buds, fewer leaves, less resin however... lets see...
