One of my greatest joys is in January when the wind is blowing, the rain or snow is pelting, but enough sun to keep it very comfortable, and I take a book out there with my two cats, who absolutely love it.

Keeping the mess out of the home is worth the cost!!

If you seal up the green house making it as air tight as possible with small vents at the top and put black stones on the walkways of the green house it'll absorb and radiate heat passively. That and minimal insulation on the wood would really help.

Even in winter, plants inside the greenhouse are protected from wind. The outside plants can be robbed of their heat through windchill factor.

I feel exactly the same way with my greenhouse, its definitely my "happy place"

[Lightdancer]

Thanks!
I moved to a small house (built for me!) Behind my daughter's last fall, and brought about 70 plants from across town (McMinnville, Oregon 8b) had the tender plants in the garage last year, on my son-in law's workbench 😂
He told me he'd assemble a greenhouse if i got one, so i ordered a kit 6x8' - and he pit it up this fall! I had him tuck it with his shed on the N, and a fence on the S so it's more protected, and brought my little bistro table and one chair in, plus those tender herbs, a citrus and perennials.
I am looking forward to some of the things you've mentioned!

I have been looking online at Yoder greenhouses. I’m in Arkansas too and these are built in Arkansas. I absolutely love them. Hubby already said “ go for it”. I just might!

We live in NWT, we are building our new planta greenhouse this is our first growing season

You’re so right that it is really hard to find info on greenhouse growing. My environment is extremely cold and I can’t even grow tomatoes at all, in the summer, without one. Consequently, I have a very well-insulated five-wall polycarb greenhouse but with intensity of the sunlight here it can get to 90 when it’s 20 outside, even with automatic vents. And yet I still heat it with thermal mass AND cover the crops right now with a hoop house & a blanket- inside the greenhouse! With all the differences between climates and types of greenhouses, I think gardeners just have to adapt what they can glean from multiple sources. It takes a huge amount of trial and error. But I love it. With three feet of snow on the ground I don’t think I could tolerate the weather otherwise.

Thank you for this good basic information. Having just bought a large greenhouse and having no experience in using it, I found what you said was very helpful! Tony Haighway Shropshire, England.

[jamiereynolds]

This was good info, I am preparing to build myself a greenhouse and I totally loved all of your tips

[cyn]

Thanks for the info. Im in zone 5a and recently acquired a free small(6x8) greenhouse. I’m trying to learn fro others on what to expect and your tips were useful.

[MultiMother]

Thank you I live in Ky. Been doing it in basement for years just recently purchased a greenhouse and retired. Excited.

Have you tried using maybe a solar powered fan in your green house? It will make ur seedlings stronger, will help with air flow and might hold down any excessive humidity

Greetings from West Cork, Ireland, from a Sheehy to a McSheehy. Our ancestors probably knew each other! I've got a sunroom that I'm using as a greenhouse and it allows me to have a continuous supply of salad greens growing in pots for most of the year. In the wintertime and early spring, it's fantastic to be able to watch plants growing when it's wet or blowing a gale outside. This year I started in mid-February and I'll probably try using grow lights for the winter just like you suggest. Great channel, by the way.

The only place I could fit my glasshouse was under a large deciduous tree - not ideal I thought, but actually it is great. My glasshouse never gets too hot and although it cuts the light down a bit, I can still ripen tomatoes etc. I keep the vents open all the time and only close the doors if it’s really windy. I never heat it, Monty Don calls it a cold greenhouse, which put it all in perspective for me. I grow all my seeds in my little shed next door with grow lights and a heating pad

Thank you for your videos I am also from zone 7B and new to growing plants since finding your channel my yields and knowledge are improving.

Thank you SO much for putting out this video! I have a small heated greenhouse and have really struggled with the best way to use it. Similar to your observations, despite it being heated, the temperatures still swing VERY widely from as low as 36 degrees at night (outdoor night temp 15 degrees) to as high as 80 degrees during the day (even with shades up and outside temp at 30 degrees) - this temp swing is all within one day. Given these wide swings, I also have found it best to germinate seedlings indoors and then bring them into the green house once they are big enough. I also didn't know about hardening off going into the greenhouse so ended up killing a bunch of warm seasonseedlings last year! I found I didn't really need to harden off the cool season plants and I'm thinking this is because the sun is much lower and less intense throughout the winter season when I am sowing things like onions. I am intrigued by your grow light experience -- I wasn't sure so I had left the grow lights on all the time but I think I'll be trying what you suggested in your video and only supplementing. I would love to know how you figure out when to turn them on? Is it just when the sun goes down until about 10pm or so?

[TerribleTim]

I'm starting my first season doing this and got my greenhouse set up. I discovered a lot of the same stuff as you, it heats up very quickly and cools down just as fast once the sun goes down.
My seedlings are still very small. I'm still learning.

Great video. I retired in Nov. 21 and the first project I completed was building my greenhouse. I wish I could have done it years ago.
Very informative video.
