maintaining the ideal BPD what you guys are trying to get your VPD under control in your grow because
it's out of control maintaining the ideal vapor pressure deficit can be pretty challenging right
but we're here with the tips to help you guys get it dialed in and understand what's going on
so you can grow the best biggest plants that you possibly can help you it's your growing goals tip
number one use a VPD chart get a VPD chart go to pulsgrow.com download their super dope chart
it's super easy to understand all you have to do is look up the temperature in your tent and then
find your targeted VPD range and it will tell you what your Rh should be for that temp this
will help you adjust your environmental condition yeah and if you are using a pulse Pro you can also
go in on the app and type in your Target and it will tell you what you have to adjust your temp
and humidity too using something like the AC Infinity controller 69 is what we use to help
control our grow and maintain the BBD by ramping the exhaust fans and the humidifier increasing or
decreasing the amount it's really been detrimental to our plants growth uh using these tools so I
really helped us dial it in tip number two you can measure your BPD measure regularly watch it know
what's going on know the temps and the humidity and what the VPD is for that at those ranges and
then make sure you're trying to maintain over that growth we use our controller 69 or Paul's
Pro it will both give great VPD rebounds and do those calculations for you so you can monitor
live in your growth another important thing to know about calculating VPD is leaf temperature
offset this is a difference in the air in the tent around the canopy and then the actual leaves of
the plant because that has a factor in how VPD is calculated it's good to take measurements with an
IR heat gun of the leaves around your canopy and then get an average most monitors have a
way to enter in the leaf temperature offset so you can get the most accurate VPD readings from your
device as long as you can monitor your temperature in RH you can calculate your VPD so there are free
calculators online we use some instruments that just monitor it for us with Easy Web apps that
we can pull up tip number three adjust your temperature and humidity in the grow so being
able to control your temp and humidity is going to play a huge part in how you can control your
VPD because you have to be able to control your relative humidity and the temperatures as best as
you can to hit that Target BPD the controller 69 has helped us do that yeah what's really
helped us with that is the controller 69 and the exhaust fans from AC Infinity um and also their
new humidifier units that can plug in so you can actually go on there and then set up your Target
vpds and it will ramp the fans and the humidifier to try and maintain that Target which is straight
up yeah it's changed it's really helped a lot in helping automate the process of controlling VPD
um so it's been a huge thing for our grow is just understanding how to use those fans and
ramp the speeds um to be able to maintain that temperature and Rh to keep the VPD at a Target
just it's worked really well there's a dehumidifier or a humidifier that will
help remove moisture or add moisture to the air in your grow it might be better beneficial for you
to do the whole room that your grows in or maybe just your tent in a smaller thing yeah but it is
important to figure out how you can set something up that's going to automate those to control
there's a lot of great controllers like ink bird and AC Infinity control plugs and stuff like that
that are going to help you automate the process of controlling your moisture and temperature last tip
air circulation proper air circulation is a must guys got to keep that air moving in the tent got
to keep it flowing the last thing you want is just stagnant air that's not moving and you're growing
it's critical for maintaining the VPD levels yeah it's definitely going to help keep your VPD
dialed and make sure the entire environment is is dialed in rather than just one single area because
nothing's moving so right circulation clip-on fans make sure your exhaust is right and you have
an airflow or a negative uh air pressure in the tent so it's always pulling in and filtering out
um so you really want to keep that airflow dialed it's going to help you keep your VPD done this
will also help prevent the buildup of humidity in heat Pockets anywhere in your town yeah help
to make sure that you're keeping down past keeping down the risk of mold especially if you're keeping
it in the Target ranges um you know excess moisture in the air is going to lead to more
fungus gnats and things like that it's also going to lead to Bud rot and potentially powdery mildew
um so you know maintaining all that is going to help you guys dial that in
addiction fluctuations and humidity or temperature yup and then obviously some of that is out of your
control but do the best you can to make sure that you can maintain your temperature and
humidity levels in your grow um even if there's you know some kind of issue or maybe I understand
this can be challenging it can be challenging and sometimes you can just do what you can do
you know but if you're really keeping it dialed as best you can um you're going to have the best
results and the best grow possible with the healthiest looking plants because they'll be
able to breathe I'll take their nutrients and grow to the best of their ability yes
when you maintain your VPD you're maintaining the best environment uh so your plants can breathe
keep dialed Pam hope those tips helped you guys understand BBD and how you can help control it
