I am interested to hear from people with indoor systems.
My parental figures who think I will always be their "baby" were worried about my AP project because some far off acquaintance of the family destroyed their house with something "similar." My first though was, I am not a pot head so I am not that stupid, as this individual most likely was in my book.
Anyway they claimed they had to redo all the drywall because of mold and replace the ducting ...
Now I already thought about getting a dehumidifier anyway but really wanted to hear from others with indoor systems to see just how big of a problem it is for you and what you are doing to combat it.
My system will use a 300gal tank with LED lights and the HID's will only be on 4 hours a day (should be a huge factor in having less humidity via evaporation)
Wood or if you have a plumbing supply place that will give you an account you can get pvc pipe and fittings pretty cheap. Depends on if you are more comfortable with wood and screws or PVC pipe and fittings.
On another note. You might think of using the mylar emergency blankets like from the camping section of the department store. They won't give you full blackout for your tent but they will give you a nice reflective surface for a fraction of the cost of the fancy mylar from the hydroponics store. It isn't that sturdy so if it needs to support more than its self you will need a backing but I used it as a curtain to keep the light from my hydroponics from driving us from our living room when we were apartment dwellers.
I like both wood and pvc ... have done a lot of "side construction" for my father growing up :D pretty much know enough now to build everything in a house but the roof. The wood would be nice because it has a flat surface to attach the films to easier than the piping. And its dirt cheap for 2x2, like a buck each. While PVC is nice because you could do wild things like "expanding tents" by placing a 3/4" inside a 1" for instance then using it as a rail to attach two 1" together knowing you will pull them apart later.
As far as using the Eblanket from what I have gathered they are really really flimsy, hard to get flush, will create "hot spots," are dirt cheap, might already have holes in them, reflect 70% visible light and 90% IR light.
White paint can reflect 90% of all light, as can the panda poly :D
I have thought of using it still despite this in a sandwich between black canvas and panda poly to get more IR reflection. But I might just try to find some cheap insulation foam sheets and place them on the frame and place the panda poly inside the frame then cover it with more panda poly or another material to hide how ugly it is going to look
I had another thought too, and I haven't exactly worked on the fine details, but it would be really interesting to have dual climate zones in the tent. One from the GB down being cooler than the one from the BG up as plants like it this way .... It would add more levels of difficulty to the project but it would be interesting.
A simple way of doing this would be to get a "cooler" for the FT and keep the rest of the room at temperature this way the GB / FT will be about the same temperature ... I have never used a cooler before though so this might be overkill. Another Idea would be to some how vent the AC to cool the FT or just lower part of the tent. While this would work in the summer it would require tweeking. Ultimately a "valve" to adjust flow from both the heat and AC lines coming into the tent for both zones would be needed >./p>
You could also physically separate the two layers with poly then simply use a separate vent for each with thermostat. This would require possibly removing to work with the system ... but if the walls are made so they roll up for instance on each side then removing it would not be required most of the time. This option would be the easiest I think.
Just make yourself a little flap so you can stick your head in to watch the fish and to feed them.
what kind of fish are you planning?
Just curious why you need such a big fish tank in this case? Especially if you are going to have a sump?
If you wind up changing your layout to use a sump, you could probably do a smaller fish tank more appropriate to your fish stock. Seeing as the system is indoors you don't really have to worry about extreme temperature fluctuations that usually cause people to go for the 300 gallon fish tank as the minimum.
lol yeah ... while I could find a 320gal to fit through the door the cost for the extra "20" gallons is not even close to worth it :) So the 300gal Rubbermaid will be awesome ... Seems most fish cant see above 600nm unless they are a predator, maybe I will throw some of my extra LED's down there so I can see them at night ... I should have ordered more LED's to make a fishlight for them since they like 10 hours of light a day and LED's wont increase the temperature of the water :D
