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.
Β 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.Β 
Some of Ashley’s interests are YouTube, in which she posts informative videos about plants and gardening. The focus of Ashley’s YouTube 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 YouTube channel as well as her reach to up and coming gardeners.Β

    Great video! Very informative. Here in Calgary we get chinooks and we have gotten snow fall in July and or August. This would definitely help in such a scenario! At least with smaller containers. I think I may build a greenhouse for on my deck with a wall that can open in the summer! You have given me lots to think of. Thank you!

  2. Danielle Brogden on July 29, 2021 at 9:21 pm

    Nice video! What type of greenhouse is that? Looks relatively easy to dyi

  3. Jay Frank on July 29, 2021 at 9:22 pm

    I kid you not , last night I wonder if she’ll ever do a video on "geothermal greenhouses" but this’ll do πŸ‘πŸ‘

    It’s very convenient that Edmonton is on zone 3 because I can just refer back to your video when I plan to start gardening. I don’t know anything about plants and gardening but when I move into a house that has a yard I’ll start planting food to reduce my waste πŸ™‚

    Love heat sinks they can help
    I like these style greenhouses how do they hold up to the wind?
    You can get auto door window opener when it gets warm it opens to vent

    I built a greenhouse out cattle panels 6 years ago. There is a YouTube by Texas Prepper 2 on how to build it. I’m in a zone 5a Canada area and get lots of snow and wind. ever a problem. It was cheap to build and has been durable. For me green houses are fun but not useful most of the year. The best use I get from mine is in the spring. I can get my seedling out from under lights and into the sun a few earlier. Nothing beats sun for growth and strengthening plants. The greenhouse helps harden the plants before going into the garden. The rest of the summer I keep my cacti in the green house with the door and window open. That way they get plenty of heat and sun but are protected form excess rain. Tip for anyone who plans to use clear plastic on the greenhouse. Don’t do it. Get a proper cloudy uv protected greenhouse plastic that blocks a good percent of the sun. If you use clear plastic you will cook your plants. If is not uv stable it will break down under the sun in short order.

    Your garden looks beautiful. My last dream is to have a garden like yours

  9. Melissa on July 29, 2021 at 9:33 pm

    Thank you! I don’t have a clue..newbieπŸ˜‡

  10. Cedric Nicholson on July 29, 2021 at 9:33 pm

    Hi I’m in Calgary, do you have direct sun during the day in the winter? I ask because I have a north backing patio but I don’t get direct sun in winter because of my building. We do get chinooks but I’m trying to figure out if I can get away without using a heater. Also how much is you electric bill when you use it consistently during a cold snap?

  11. OKSlinky on July 29, 2021 at 9:33 pm

    This was so perfect! Edmonton is apparently a zone 3 as well and I was wondering about greenhouses. This had all the information I was looking for and I love your channel so much~

  12. Charlene Stevens on July 29, 2021 at 9:36 pm

    Very helpful. ThisIs my first year with my backyard greenhouse and I have my fingers crossed! Thank you for all the information

  13. Katie Lake Farm and Cottages on July 29, 2021 at 9:38 pm

    Great information.

    I have been looking at different types of greenhouses for a year. So much to consider. I presently use tunnels heated with crock pots. I have about 90 square feet. Thankyou for your video. I will use your links.

  16. Janet Ursel on July 29, 2021 at 9:45 pm

    How cold is too cold? I can’t imagine you’re doing this in mid-January…

  17. smlaks Vern on July 29, 2021 at 9:46 pm

    I’m in Canada as well & I’m pretty chicken in getting my plants in my greenhouse. After watching this video, I may give it a try.

  18. Mike the cave man on July 29, 2021 at 9:52 pm

    Great topic

  19. Loriful on July 29, 2021 at 9:53 pm

    Those geodesic domes look fun to build, and very useful! I can imagine all the great wonders of the world being built because of that tropical fungus that makes ants climb to the tops of trees. like if daVinci was so inspired by cor-de-ceps or however you spell it, it would be silly to imagine that, since we humans are already over-the-top with the things we build~

    Good ole’ Ukrainian boy from Saskachewan… homegrown organic stock!

  22. Sarah McHugh on July 29, 2021 at 9:57 pm

    My friend taught me a big plastic barrel filled with green grass clippings heats up wonderful and helps as a great heat sink, which helps up here in the Yukon

    I apologise for the off topic question.

    I live in New York Queens zone 6b.
    Can I grow asparagus under or near a fig tree?
    Would it be a good companion?

    Could you also please tell me which type of asparagus is the tastiest for my zone?

    When I buy asparagus from this store, they are thick and stringy and very hard to chew, so I clean them with the potato peeler. When I boil them, they are also stringy and unpleasant to swallow.
    I never ate a freshly harvest before so I don’t know if that is a common thing or it is just a specific type that is like that.

    oh, I am planning to do a no till garden and occasionally adding leafes and wood chips.
    I want to create an organic garden.

  24. Alberta PATRIOT on July 29, 2021 at 10:06 pm

    I wish we could put that type of greenhouse. We are in high wind and snow load area in foothills.

    We grow our tomatoes peppers and melons in unheated greenhouses.

  25. Dodo Pson on July 29, 2021 at 10:07 pm

    Glad you commented on channel makers πŸ˜ƒ occasionally I find a channel there that seems worth checking out, yours being one of them.
    Would you be interested in doing a video about passive solar greenhouses? The Chinese one and the ghat(?) system. Whether or not they’re worth it, especially the ghat one; it seems super expensive.
    I’m in zone 7, maybe even 8 nowadays. Growing tropical plants in a passive solar greenhouse seemed fun, but I’m not sure if it’s worth the expenses 🀣

  26. Lotus Leaf on July 29, 2021 at 10:07 pm

    Hi Ashley, thanks for the video

  27. C C on July 29, 2021 at 10:09 pm

    My issue with my small plastic greenhouse wasn’t heat. It was fungal spores that took out a lot of my peppers eggplant tomato and ground cherry plants 😫. We are experiencing a little longer cool nights than usual in New York as well as late damp weather so things are not going very well for me in my plastic A-frame low tunnel that I got off of Amazon I had such high hopes for doing a higher volume of plants by moving them out to harden off in the tent and then letting them chill out there until it was ready to plant them but I’m about a week from when it’s safe to plant and our lows are still in the 40s sucks a lot of my stems on my tomatoes have no hairs left on them some of them got Colorado and I had to treat with copper fungicide. Some of them have yellow lower leaves withBrown margins so I don’t even know if I should plant some of them it looks like an early flight or a leaf spot I don’t know I think I just tried to go to hard this year and things got away from me as well as the weather not cooperating as usual.

  28. Scott Smith on July 29, 2021 at 10:12 pm

    Am going to build a small starter greenhouse, not with fancy auto vents or anything. Watched alot of videos on cattle panel greenhouses. I like this system also. With lumber prices being so crazy now, was thinking cattle panels is way to go, but 1x2s aren’t too bad in cost. Now not sure, but I do like those end pieces he developed.

  29. Corinne Lutter on July 29, 2021 at 10:14 pm

    What does the greenhouse look like from the outside with the poly on it? How did you put the poly on?
