  • I’m about to tell you the ultimate secret when it comes to getting huge houseplants or rapid growth from houseplants. Wanting houseplants that grow quickly? You definitely want to look up vapour pressure deficit. This is especially true if your growing your house plants in an IKEA cabinet greenhouse this is a must follow. VPD or vapour pressure deficit refers to the amount of moisture in the air compared to the temperature. I’m going to skip you the boring details when it comes to VPD and allow you to look that up on your own. I want to get to the meat and potatoes of the entire discussion.

    Ashley is an agronomist who has had a passion for plants since she was a small child. In the long summers as a child, she would garden alongside her grandmother and it was then that she realized her love for greenery. With years of great studying, Ashley had begun her post-secondary education at the University of Saskatchewan.
    At first, her second love, animals, was the career path she chose but while doing her undergrad she realized that her education would take her elsewhere. And with that, four years later she graduated from the University of Saskatchewan with a bachelor’s degree in science and a major in Soil Science.
    Some of Ashley’s interests are TH-cam, in which she posts informative videos about plants and gardening. The focus of Ashley’s TH-cam channel is to bring science to gardening in a way that is informative but also helpful to others learning to garden. She also talks about the importance of having your own garden and the joys of gardening indoors. Ashley continues to study plants in her free time and hopes to expand her TH-cam channel as well as her reach to up-and-coming gardeners.

      Hey there my fellow plant nerd! I am learning all that I can about Korean natural farming, I found a book called Jadam, ultra low cost farming, there are solutions like lactobacillus, Jadam Microbial solution aka JMS, and all sorts of interesting solutions, im saving up to buy the book but in the mean time am learning from other youtubers that have embraced the methods, I really want to learn what you think about it, and teach us how to make the solutions if possible. Please look into it, the book is on Amazon. My name is Adam, I live in Orlando, Florida USA, our soil here is grey sand with no hope of natural organic matter, I actually went to the woods looking for healthier soil and couldn't find any, I cant understand how a forest could be without tons of compost but thats how it is here, anyway Im starting a business this year selling tomatoes grown from my yard and need all the help I can get in amending the soil here. I have tons of questions but feel I already wrote too much. (Quick Question) Should I till in cover crops or leave on top? Crimson clover

      This was really interesting to me! I have been wondering what temp and humidity to have my IKEA cabinets at and what other people were saying just isn't working. Things have been pretty stagnant for me so I'm upping the temp on the heat mats to see if I can get the temperature and humidity in a good VPD range. It will be fun to play around with things and see if I can get it in a good VPD range - and especially to see what it does to the growth on my plants!

    This explains a lot of why my houseplants struggle in winter! The room itself is cool and has a humidifier, but they're in a south-facing window with direct sunlight, so the leaves are way hotter than the rest of the room and they aren't getting enough humidity with the humidifier on low.

    This does make sense! My Meyer lemon tree seedlings like it at 60% humidity and below 80 F temperature. Every time I get even close to 60%, it’s sweating in my greenhouse tent. I have one of those infrared guns & a humidifier and I have been documenting the numbers and making adjustments according to the readings. I can’t seem to find the sweet spot. But I think this formula will help. Thanks! 🙏

      And back with the results! After hearing about how dry everyone's houses get in winter, I bought a couple of hygrometers to check my home and was pretty happy with my 65% relative humidity (rainy Seattle). But it looks like that is too high for our indoor temp of 68 F (20 C), giving me a VPD of .82 kPa. So if I'm reading this right, I actually want to bring my humidity down to about 50%. Or my temp up to 80 F 🥵

    Wow, this is so fascinating! I wonder if VPD has something to do with what people call a winter dormancy/rest? I grow a lot of orchids and other epiphytes and I've been told some of them tend to die after a few years if they don't get a cold rest during the winter. I haven't personally encountered it, but I can't help but wonder! I guess the plant is not able to "reset" their stores of sugars and nutrients?
    I also have a homemade IKEA greenhouse with average day temps around 78 F and humidity in the 70-80% range. I'm definitely going to try those formulas!

    I use humidifiers in my CBD grow tents. I keep the tents at about 50% RH when in veg state but I lower it to 30% +/- when they are in flower to avoid mold. I also closely monitor air circulation, PH, EC. I water according to the needs of the plants (I use a moisture meter) and I always add Aloe Powder or Yucca powder to the water to reduce any NPK salt build-ups and to make the water wetter and things like kelp and fish emulsions and a few other things besides fertilizer. Anyhow, just me bragging :)

    How much responsibility lies on the plants' ability to transport water from the soil and throughout the plant, for causing different humidity requirements in different plants? What else is affecting this, e.g. size of stomata, how easily the plant can open/close their stomata, etc.?

      That’s a great question. If you watch my video on snake plants I talk a little bit about C3 and C4 plants. This would give you the best answer as to why some plants have different requirements for humidity.

    Hi, thanks for all of your content! How can we apply this in the summer if one doesn't have an AC? It gets about 30/35°C where i live and keeping the humidity in the room at 80% would probably cause mold issues so I'm wondering what course of action would be best.

    So is the chart showing the “ambient VPD”? I bought a hygrometer that has VPD on it but I’m not sure what it’s measuring if VPD is based on the difference between the room VPD and the leaf surface VPD.

    Great show. Just the needed information. I have some maturing plants in a controlled environment. Because of equipment and sensitivity limits I can run a relatively low VPD (1.1 kPa-1.36 kPa) or a bit high VPD (1.3 kPa - 1.65 kPa).
    Which option should I choose? Stress them a bit or give them an easy life?

    Hi Ashley, Love your nerdy videos! Have plant issue question, I have a fiddle leaf in my sunroom, he's about 7 years old and 7 feet tall. Been doing great in the room, then I bumped up my humidity to about 60-62%; I had been keeping it at 50-53%. I bumped for other aroids in the room. So all of the sudden my fiddle started dropping leaves, very quickly, some yellowing and just leaf drop. What's going on!!! I can't figure it out, nothing else has changed in the room. Any suggestions? Thanks

    • @GardeningInCanada
      @GardeningInCanada  2 ปีที่แล้ว

      So it’s likely that the plan isn’t used to those levels of humidity. So the old leaves have a certain number of stomata used to regulate based on the old humidity. Your new leaves that will come in at the new humidity will obviously have the stomata and the apparatus to deal with your new higher humidity.

    I have a potentially related question. I have a terrarium style begonia whose roots have been uncovered by sphagnum for almost a year. The roots have gradually turned an orange color. I thought it might be a type of oxidation from being exposed to air, light ect. What are your thoughts?

    • @GardeningInCanada
      @GardeningInCanada  2 ปีที่แล้ว

      It’s likely a hardening on the outer layers and ultimately a staining from decomp. So roots to us look like tubes but in reality they are almost like a bunch of tiny plates stacked up on eachother. So as those plates thicken to protect from dehydration in your case it can cause also a staining effect. Completely normal don’t stress it

    • @begoniasarawak
      @begoniasarawak 2 ปีที่แล้ว +1

      @@GardeningInCanada Thank you for the information! So the plant will trigger the roots to thicken to prevent dehydration. I'm assuming because the plant thinks since the roots are exposed to air/wind/light its more prone to dehydration.

    That's pretty interesting. I'm well outside of that range however I only get direct southern light in the winter, due to large maple and oak trees in my backyard, which leaves my Christmas cactus very confused and refusing to flower. I bought a cheap hygrometer, which does appear to work, however when I run the ionizing humidifier, it doesn't register on the meter, even though you can see the vapour haze in the sunlight. Cooking and showering immediately registers. I think it must not be able to read the wet bulb temperature of the ionized water. Any thoughts?

    Holy Moly! Here I am fighting to keep my to keep my humidity above 30, but help me to make sure I am understanding this correctly! Daytime temp in our home is consistent at 21, so I need to keep my RH between 22% and 52%? Which it is, but at night our home temp drops to 16.5 so I need to keep humidity below 36? So rule of thumb is: higher the heat, higher the humidity? So, for a plant like my P. el choco that seems to need higher humidity, there's no point (maybe point is the wrong word, it's not optimum) without increasing the temp too? Am I simplifying this too much?

    • @GardeningInCanada

A 'simplified' ambient look at 72% - the chart says I need to raise the temperature to 30 + celsius, yikes that is so not going to happen!

      VPD = inverse RH. If you have a low VPD increase humidity, if it's high decrease humidity. This is just science complicating common sense. Most plant ppl commonly understand each species needs it's own amount of humidity and that varies by temperature. IRL, ppl almost always just refer to RH as humidity because there's no point in discussing absolute humidity outside of temperature in the real world. A suggestion to adjust your RH or VPD amounts to exactly the same thing.

    Thanks for the video. This is a very interesting subject. I have a few words of constructive criticism for you to either use or discard, whichever you wish. The video is unnecessarily long. I would bet most people were interested by the title but stopped watching once they realized how long it is and how long it's going to take before you give them the info they want. I know it's hard to trim things down sometimes but this would be a lot easier to sit through if it were not as verbose. The audio has some issues that make it a bit frustrating to listen to. Because of the very slow pace, I sped up the video. This means I have to turn the volume up in order to keep it sounding clear. The dogs are super cute but the sound of them walking around gets picked up by the microphone and that became frustrating after a while. You also have a tendency to use vocal fry, which a lot of people find unpleasant or irritating. It's a fairly simple thing to correct and there are videos here on TH-cam that could help. Some content creators appreciate this kind of feedback because it lets them know what they can improve in order to be more appealing to a wider audience.
