color:#1F497D'>I’ve had to look at humidity issues for indoor pools,
indoor gardens, living walls - and it is a really difficult issue to deal
with. Plants (especially food plants) need moisture and they transpire so
you have two choices. One is to maintain a moist environment to reduce transpiration
rates or to water heavily and ventilate heavily. So the growing environment
needs to be made of materials that can handle moisture and has some antifungal
properties – our living environments (including soft furnishings, clothing,
etc.) are not made of these materials so there is a big conflict. Our
health is also compromised by excessive humidity.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>So, ideally you isolate the growing environment from the living
environment and accomplishing that in an urban environment (without greenspace,
roofspace or deckspace) is difficult. Food production also requires a lot
of human energy that I have found people have a hard time maintaining. <o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>I like collective gardening approaches where some local
greenspace or roofspace is shared in some way. In my community I have found
people that are much better at growing things than I am so I support them.<o:p></o:p></span></p>

that hang out (or in) and replace an existing window. A 3x4 window using the
square foot gardening approach on two layers can have about 60 foodplants in production.
Easy to isolate and can be heated with ventilation exhaust and could even be
vented to a HWHP.<o:p></o:p></span></p>

to John Salmen's point that growing crops indoors can<br>
be very harmful to the structure.<br>
I'm sure there are ways to solve the problems, I'm just not sure there<br>
are efficient ways to do so.<br>

Why? Profit motive is high. Why not use some of what they know and build
upon it? The only parts that may not be helpful are the parts that make
it necessary to do it secretively....that is what leads to the destruction of
houses, unfortunately. Still--they have climate control (temperature and
light) down to a state-of-the-art science and that is the hurdle in growing
plants indoors.<br>
