What is vapor pressure deficit?
Often, marijuana growers who have their plants in indoor grow tents or rooms with artificial lighting, take into account parameters such as temperature and relative humidity to maximize plants growth and bloom, thus obtaining abundant harvest with top quality flowers. As we will see later, these factors affect different processes of the plant, such as transpiration or nutrient uptake.
However, we usually forget about another important factor that is related to the aforementioned ones: vapor pressure deficit or VPD. Broadly speaking, VPD is the difference between the amount of water vapor that the atmosphere is able to retain (which depends on temperature) and the amount of water vapor contained in it (relative humidity). It is usually measured in kilopascals (kPa).
Providing our plants with a correct relationship between temperature and relative moisture will keep us on the right VPD parameters, increasing the plantβs activity and thus improving its growth and showing its full potential during the flowering phase. The ideal would be to adjust both parameters (temperature and humidity) to get the best possible VPD value, so that the development of plants will be amazing.
In the chart above you can see the right temperature and moisture values to maximize the development of cannabis plants. The green zone shows you optimal values of VPD, in which it would be ideal to maintain the environment. The orange zone shows correct values, in which plants should not have problems to develop normally. However, red areas show values in which your plants will be very far from hit their full potential, since the relation between temperature and moisture is not optimal.
With relatively high values of VPD (between 5 and 12) plants tend to open their stomata and release a considerable amount of water vapor into the environment (increasing their transpiration). This increase in transpiration results in an increase in the plantβs photosynthetic activity, which will need more nutrients and will improve its overall growth, both during growth and bloom. The best range is between 7.5 and 10.5, which we have marked in green. However, we must be careful that VPD is not too high (dark red zone) since the plant would close its stomata to avoid releasing too much water vapor to the environment, which would result in fast dehydration due to excessive transpiration.
On the other hand, if VPD is too low (light red zone), the plant will also close its stomata for not releasing more water into the atmosphere, which in this case would be already saturated (it would have reached the maximum water retention capacity in a specific temperature). In this way, reducing transpiration will also reduce photosynthesis, which has a direct impact on the plantβs development and yield.
That way, VPD is essential when it comes to offer the best conditions for the development of plants, also to understand its water requirements according to the nutrients used and thus adjust them correctly to meet the growerβs expectations.

I shouldn't start it under the 600w MH, she started Veg instead of making roots ....π
Not your cup of tea mang? The only Gorilla Glue #4 I've had was from a dispensary at $280 CAN an ounce but it was the stickiest of the ickyest. Hoping I can find a seed that compares to the clone
@TheFairyBudMother,well well well ... it is actually getting better . Reading your comment made me roll a joint π π π Puffing on it just right now πππ She is better than Sunday when I've smoked some. I really like that strain π
I have to say I really do like your support structure frame. I'm loving how many people on here are building their own custom equipment for their grows, yourself included. I can't wait to see how your glue turns out mate. Cheers :D
@DabCrab,Thanks, it makes it easier for watering . I agree , people's can be very creative when it's for growing Cannabis π. She shall finish with 5-6 big colas , I hope π
Wow I am glad I read this. This is what GD is all about! The breeder said it was mostly sativa!!!!!! I would have been really really upset buying a plant I expected to be sativa like and instead it's Indica!!!!! Thanks for saving me!!!!!
@The_Projexx, yes , after super cropping sometimes the stems get heavily damaged , you just need to fix it with some duct tape when the stem didn't split in 2 parts !
@JUNGLE_B4RNS, I grow dwc. Most fertilizer has way way to much N P K for DWC quality nutrients will indicate concentrations for different mediums. For instance I use aqua flakes for week 2 veg in coco you use 6.5ml/g, in soil you use 9.5 and for DWC you use 3ml per gallon!!!
@Tazard1,Thanks, it's a lot of work. There's only the half of the informations, the other half is on a personal dairie. N P K Ca Mg So has nothing to do in the photosynthetic equation Light + H2O + CO2 = Sugar + O2 , it's all about Candy farmers VS Salt farmers. I only grow in soil.
luv the grow boss to lol, i always felt the way he does, hell i even started out with t5's lol. still using one atm in a shotgun grow before i remodel. anyway, was that gg4 a clone? i'd love to get hold of some of that one day but i cannot find real gg4 seeds and i don't have access to any clones either. the best i can do is maybe get gorilla bomb from bomb seeds which was crossed with a real gg4 cutting
@JUNGLE_B4RNS,
if you learned from it, it's not a failure, it is the cost of education.. if you learned nothing, then you failed for sure!
That $100 mistake will pay you back $1000s over the years.... WINNING
@BrafZachland, It's a gift from a famous Seed Bank . Got 2 seeds left .
I'm not having a successful plant ... I received the seeds 3 weeks after starting this run , popping them under the 600w MH wasn't the best thing to do , then I didn't had a real plan , ScrOG or 30" plants .... wanted to grow a winning award 30" fenotype at first , then I decided to scrog it to get a better yield , that was another bad idea ... finally i've broken one main stem (100$ clone for that broken part) witch isn't recovering.... a fucking tragedy π’ I won't get my super fenotype neither a good yield ! Epic failure π
@CBD_Sweden,Thanks . They're not accurately at 100% with the feeding and watering schedules. Half of my notes are on GrowDairies , the other half is on a personal dairie π
sorry to hear that, i am also experiencing a nightmare i added a bagseed to my grow and it was a herm, it didn't spread i don't think, but it's all in week 5 of journal, pics to come. i needed to fill my 4th bucket and i knew better and this is what happens. plus my whole grow was not planned it was last min before remodel and changing buckets without rdwc is a hassle and so is getting rid of drained soil water each watering etc... i like automation lol. ebb flow or rdwc. can't wait till this grow is over
Hi and congratulation to such a beautiful Plant . i tried to find aout how ypu arranged the bamboo sticks and the "web" with bamboo sticks and rope. did you put the big stick in the cormer and then Build the web= with smaller bamboo and rope? its a nice solution i got so much bamboo in my garden and i think it fits together bamboo and weed. ok have a good time greetings from sunny Germany
