In the coming months I will finally be building a greenhouse/hothouse (still don't know what the difference is lol)
Construction will be of brick with large window inserts and a pitched roof with polycarbonate sheeting.
The reason for building with bricks is for 2 reasons, the first being to reduce temperature fluctuations and secondly because my best friend is a bricky so its going to massively reduce the build cost.
The flooring will be entirely concrete, I do not plan to have any cut outs or open garden beds in the greenhouse as I have heard they can be hit and miss and often lead to infestations of various nasties.
I will be having the roof trusses made up professionally as they are not that expensive and I want the house to look nice and not be a slap stick job.
Will also be having an electrician come out to wire up a ceiling fan for airflow.
Also plan to install guttering so the roof can catch the rain water and I will plumb up some water drums at the back so my plants can finally live exclusively on rain water which I am sure they will love.
The shape will be a long rectangle and eventually I want to build a patio on the long side that faces the yard, would like to cover this and have the larger plants live outside but just have to wait and see how much yard space I can negotiate with the other half (this intended build has already cost me dearly! ha ha ha)
I do however have a few blanks to fill in....
1. Is orientation all that important given how strong the sun is down here in melbourne?
(I would like to build it running along the fence so it doesn't cut into the yard too much as I intend to build it quite big)
2. If 1 side is facing the fence (the long side) is there any point in putting windows on this side or should I just leave it as a brick wall?
(if it is a brick wall it will be better as I can then put up shelving, the majority of the other walls will be all window)
3. In terms of the polycarbonate for the roof does anyone have any recommendations on what brand to use?
(i'd rather spend a bit extra and get some life out of it rather than having to replace it 18 months later)
4. Any suggestions for balancing the needs of cacti that love strong sunlight and their more sensitive counter parts?
(I wondered if putting up blinds on one end might help and the astro's and what not can live down that end?)
I'm assuming that with a completely clear roof there is going to be a hella lot of sun coming through coupled with the windows its going to be a pretty bright house but i'd rather it be too bright and then shade the individuals than have plants reaching for the light.
The build won't start until at least December but I am starting to do the groundwork now so that all my ducks are in a row before I start building, after all it is going to be brick and concrete so not like I can pick it up and move it if things aren't right!
