Building a Greenhouse

We would like to do a wooden framed greenhouse in northern AL.  It's just for potted plants only. Questions I have....

1.Should we go with a kit, or should we build one?

2.Is concrete slab ok?

3.What kind of glass should we use?

4.I have shade plants and sun plants going into the house. Is that bad to have them together? Is it ok for shaded plants to be in a mostly sun greenhouse?

5.The green house is in morning shade afternoon sun. Is that ok? 

6.Is it ok to leave the plants in it year round as long as it's well vented & good air circulation?

Thanks in advance. I really am just getting started and have no clue. My mother recently passed away and she had an awesome green thumb. I have no room in my house like she did with her plants so we are doing a greenhouse memorial for her at our house as I'm inheriting all of her plants.

  • 1.  Depends upon your handyman ( handyperson ) and carpentry skills.

    2.  Concrete slabs as a base are fine if you are sure you will never want to have soil beds in there. If your usage might change, an interior gravel floor may be a good idea leaving the concrete for the actual frame base. 

    3.  Horticultural glass is probably the cheapest but a better bet is the toughened safety glass.  Polycarbonate sheets are fine but not as attractive.

    4.  You will need to provide shade at some point - probably even for your sun lovers.  You can do this internally or externally with blinds.

    5.  The usual "classic" orientation for a G/H  is for the ridge to run East/ West.

    6.  If your plants are tender ( house plants, etc. ) then you will need to provide heat over winter.  You can provide frost protection by various means if necessary.  It really depends on what you plan to keep in the G/H and, of course, your geographical locationimage

    Forgive me if I'm asking a stupid question, but does " AL" mean Alabama? 

    Most, but not all, members on this forum are bases in UK. 

    Local knowledge is key for us gardeners.

    I hate to contradict Philippa, but I'd align a greenhouse ridge North South, so one the East side gets morning sun, mid-day sun shines down its length and the West side gets afternoon sun.  Very often the site dictates which way round the greenhouse goes.

  • You are quite right to contradict me Hostafan - I've never yet sited any GH ridge East/West - must have had East/West on the brainimage

    If you want to grow crops all year round in your greenhouse then it should be aligned East/West but Summer crops only then the Greenhouse should be aligned North/South so you were both correct image

    The orientation depends somewhat on the purpose of the g/h.

    I have my new one aligned East/West as I'll grow toms in a long bed on the N side and I have shelving on the S side. So the toms will get sun all day. I'll grow a few peppers and chili on the shelf side but it'll be mostly toms in the summer and the S facing side will have little in it.
