In the previous two posts we discussed heating and cooling of your greenhouse. This post is about where you might put it, and how large do you want it.
Location actually should be the first consideration, as this could impact how big of a greenhouse you might be able to have.
You want to place your greenhouse so that it gets as much sun as possible, during the timeframes that you intend on using it.
If you have wide open space that receives full sun all year round, then you don’t have to worry much about it. Put the biggest greenhouse you can afford there, and you’re good to go.
For those who are confined in a small yard, you do need to make the decision of where the sun shines at different times of the year. Buildings and trees cast shade at different angles and lengths throughout the year. At the Spring and Autumn Equinox, the sun approaches the highest in the sky with the shortest North/South angles. The shade will be nearly straight East and West (depending on where you live). In the Northern hemisphere, as spring moves to the Summer Solstice, the sun continues to move North, and the shade will grow to the largest Southerly angle. At the Summer Solstice, the angle switches over, and the shadows start to retreat. The shade will reach its largest Northerly angle at the Winter Solstice.
As noted previously, you want to place your greenhouse where it will get as much sun as possible and at the point in which you want to have plants growing in it.
If you have options that have equal sunlight conditions, you might want to place it at the location that will get the lesser amount of harsh wind.
Also, you should avoid a location where flooding or water flow might occur.
Size? Well, you basically should get a greenhouse as large as your location will allow, or whatever you can afford. You can always find ways to fill it up. Though, one size dependency is whether you will be heating and/or cooling it. The larger the greenhouse, the more it will take to heat or cool it.
Next post will be about whether you want a permanent greenhouse, or one that you will disassemble and store during parts of the year. If you intend to disassemble, then you likely have more options where you want to place it while it is up.
Will carry on in the next post.
