Building a grow room
-What dimension? -What material? -How will it be opened? -What kind of problems will I run into?
Dimensions: the dimension of a grow room can vary by the requirements of your plant and by the availabilities of the space. Some tables can help you deciding the measure.
Material: wood is certainly the preferible material, because of its good resistance, because it can be easily personalized (holes, screws and so on). The thickness of the wood must be related with the weight that it will have to support. Consider the weight of all the elements that will not rest on the ground (the lamp, the fan, sometimes the ballast, cables). The cabinet can be adequately made with wood panels, or laths for the structure and lighter panels. The choise is much personal and it's also dictated from practical requirements, such as the availability of tools to work the wood or similars.
Otherwise, there are grow boxes made with poles for the structure and a reflecting sheet as covering. They resolve several problems, but they have higher costs. You can also use plasterboards, because they are more economic, but they will increase the difficulty level.
Growroom Access: the grow room access is the critical part of the construction, but its realization depends on the type of grow room that you are going to build. The more immediate part to realize is the door (like a cupboard), for which hinges will be necessary, together with an adequate measure in order to avoid light infiltrations (the door must be high than the cabinet), but it cannot touch the ground, otherwise it will be not easy to open it, and it must remain independently closed. There are various solutions: a small door can be made, using smaller laths to guarantee the closing.
For particularly small grow rooms, a simple front opening could be made, and if our closet it's well-constructed, it will be enough to lean the "roof". The main problem of this type of opening is the difficulty of the operations with grown plants.
However, you must pay attention to the weight of the door, because it could break or fold the walls and, if the closet is not precise, it will not touch all the four angles, and this will make infiltration of light uncontrollables.
Possible Problems: during the construction you will pay attention to various aspects. In order to avoid wastes of light, pieces must match perfectly (when you are calculating the measures of the panels, you must consider the thickness of the wood and the assemblage). The structure must be stable, the walls must touch the ground, and you have to assemble all the pieces trying to create a good arrangement.
You also have to consider that the wood panels, mostly the thinnests, probabily will droop in the middle (they will subside).
The last problem is about the water, that could go out of the pots. Infact, if it wets the wood, it will brings several problems. You can create a big flowerpot-holder to completely cover the bottom of the grow room; it could be easily made with a net and a plastic sheet.
Moreover, it's worthwhile to make holes for the cables and to prearrange for ballast/timer/plugs, in order to avoid that cables will stand on the ground, where there is a lot of water and humidity.
