    New indoor grow tent set up

    All,
    I recently made the conversion from my basic baker's rack set up to a grow tent. I made the decision due to limited space in the rack and wanting to have more control over the environment as a means to grow more difficult species. Hopefully this post may help others who are interested in building a similar setup. This was designed to grow intermediate/highland Nepenthes, but not necessarily ultra-highlanders. I should mention for clarity sake that I am not sponsored by any of the following companies. I simply bought these due to good reviews/what was available to me at the time of purchasing. I apologize to our metric-minded growers. All information will be given in inches/feet and Fahrenheit.

    I bought a Secret Jardin DR150 which is 60" x 60" x 80" in size. This worked best for my current one bedroom apartment, though it's still quite big! Secret Jardin got great reviews compared to other grow tents. I was intrigued by the Gorilla Grow tents, but they are substantially more expensive and I don't think the quality difference would have made the biggest impact on my plants.

    I hooked up a LG Electronics LP0814WNR 8000BTU portable AC unit that was rigged to have the cool air ducted to the top of the tent with the exhaust going outdoors. The tent is in my air conditioned apartment and even though the lights produce a good amount of heat the AC rarely turns on during the day, but more about that in a bit.




    During the Fall and Winter months I will just use a duct fan connected to the window to bring in cool air at night for the needed temp. drops.

    My current lighting is a 4' 8-bulb T5 HO system by Hydro Crunch. I really like to give my plants a lot of light and am considering additional lighting. I'll hold off for the time being just to see how the plants do. This system puts off a good amount of heat but temperatures inside the tent never exceed 85F. All plants are on a 4' x 4' hydroponic flood table that has no holes drilled into it. I was fortunate to buy the floor model at a very significant price decrease at my local indoor gardening center since it had some cracks on the rims, which to me are only of aesthetic importance and means nothing at all.


    Humidity is maintained with my Pro Mist PM-60 misting system. The pump and water reservoir are outside of the tent for easy access. Four nozzles were hung below the lights so that minimal mist would touch the bulbs (see the above picture). I can't say enough good things about this Pro Mist system. I bought this back around 2006 and the pump is working just like it did the day I bought it. Great customer service and great product. Enough said.



    Two small fans are placed within the tent to give added air flow. This may change. I'm contemplating buying one larger fan that swivels back and forth on a motor.



    Both humidity and temperature are regulated with two Zoo Med Hygrotherm units. You might be able to get away with just one, but they are only rated for controlling up to 1000 Watts and the AC unit uses somewhere around 860 watts - I didn't want to risk it. So, one hygrotherm controls the AC, another controls the mister. I'm still playing around with daytime/nighttime temps and RH. Currently I have the daytime high set at 84F and a low of 59F. RH is set at 70%. I borrowed a datalogger to monitor the temp and RH changes (see below). Assuming the datalogger is accurate, the rh is maintained much higher than what the hygrotherm is set to, which isn't necessarily a bad thing! Temperature seems to be pretty spot on.



    Only time will tell how this system works out, what parts give/break first and so forth. I will keep you all informed of any major changes and am always open to suggestions from those of you who have more experience with this sort of growing setup. I'd like to thank Mato and Cory Gill who provided me with excellent information regarding this type of indoor growing system before I took the plunge.

    David

    Beware, the bottoms of those tents aren't water-tight. I used a Secret Jardin for my nepenthes for a long time, but I had to keep plastic under it and sop up water with a towel every week. Plan for this before you make your landlord unhappy.

    Very nice setup nepnc it seems very complete. I'm sure your plants will very much reward you with so much attention given to them

    By the way - this is a tell tale sign that you're a plant addict (like most of us): You have something so out of place in your home that guests have to ask something such as "What the heck is that thing by the window?"

    Thanks for the heads-up, Carbonetc. So far the bottom of the tent has been nearly bone dry since all the water is caught in the flood tray, but I'll pull some plastic underneath the tent just to play it safe.

    Really sweet setup, I love the robcantleyi in the back there! That sneaky little Cephalotus also made me laugh.

    Followed by the neighbors getting mad at you because your "infernal night light" makes it impossible for them to sleep. I've had people come over and ask me how I glued those "colorful decorations" - ie, pitchers - onto my Nepenthes.

    I used to have a grow tent, and I can tell you from years of experience def put a plastic tarp down to collect water or youll have a mildewy carpet lol. I decided to keep more toothy rare plants, so I went down to a deep freeze ice chest

    It's the condensation that rolls down the walls that gets you. There's no way to catch it without permanently affixing some sort of collector along the walls at the bottom.

    You'll also find that the poles will rust pretty badly in high humidity. But PVC can be found in the hardware store that's the exact same diameter as the poles. You could swap out the metal for PVC and never have to worry about it. I don't know how this changes how much load the tent can withstand, but it doesn't look like you're hanging much.

    This is something I may have forgotten to mention when we talked about it. It's actually common practice for hydro stores to recommend placing these types of tents on top of pallets with some sort of platform, such as a 4x4 piece of plywood.
