  1. I've got a bit of a security issue at the moment and could do with some help. I'm growing in a bedroom and the window is passed by closely by the neighbours. I've got some blackout curtains up and the window sits slightly ajar so I can vent my exhausted air out into the world. When I was germinating and needed to keep the temps and humidity up, the window was closed and the dehumidifier wasn't switched on. Consequently the humidity climbed quickly. Noticing this I got the dehumidifier running and the air in the room dried up. The window is open during the daytime now and the environment is fine. However, during this brief period of high humidity, moisture has got inside the double glazed panels and is just sitting there and hasn't shown any signs of drying up. From the outside what people can see is a blacked-out room with a moisture affected window when all the other windows are dry. Obviously this has got me a bit concerned that someone who knows what to look for might notice this and report it to the landlord. The windows are likely old and not sealing as well as they once did but does anyone have any tips for removing the moisture from the gap between the panels without physically having to take anything apart? Cheers in advance.
  2. I've just opened my tent to find condensation all over the lower part of it while my humidity meter reads 39%. My temperature is 25.5c while my fan seems to be running at low speed, which is set at 30%. Is my problem that my low speed set point is too low for the transpiration level of the plants while the correct temperature is being maintain so easily by the fan? Does that make sense to anyone else? Ta Fax
  3. Hey there, So I have a number of questions related to my enviroment which I will try and number to make it easier. Ok so my plan is a 1kw parabolc in a 1.2 x 1.2 x 2.2 metre tent (green qube). Using DWC ( 2 100litre coolers) and SMS Hybrid controller. Now my original plan was to get an 8" RVK L1 so I could upgrade in future if neccessary. However I have been advised that it is too big for tent my size even on controller. I read that a fan shouldnt be turned below 40% and was told that an 8" would be, especially in winter. This will cause it to burn out. So I have a number of options. There is a vent in the bedroom where the chimney was (fireplace was taken out recently as we got the whole house plastered and vent is now there instead). I can intake from the fireplace and extract into the room or else extract through the fireplace. This is a close family members house so I cant do anything major. Beneath the vent the hole is about 7 inches long and 3 to four inches high. Now this doesnt fit the 6" or 8" ducting. 1. Can I cut through this plasterboard to make it bigger (under the vent it is just plaster board and hasnt been skimmed over like the rest of the wall)? 2. Will intaking through the fireplace bring in nasties (even with bug catcher over it)? Will it be stale air? 3. I can extract through the chimney and intake from the room. Also I could possibly put black out lining on the window in the the room with net curtains in front of it fro summer. Cut a hole and attach spigot to the black out lining as a fresh air intake. Issue with this is I would prefer not to keep the window open all the time and im afraid that houses across the way (20 feet) might see that it doesnt look right. 4. Will extracting through the chimney cause lots of condensation in winter time due to hot air meeting cold. Im afraid of water streaming down the chimney as it isnt my house. Chimeny isnt shared with neighbours im pretty sure. I have heard people mentioning dryer vents not sure exactly what they are or how they work. Have found some on ebay i think but only 4". I think this might work. Its a condensation trap. (Description: 10mm, 125mm and 150mm Condensation Traps, for fitting in vertical rigid PVCu pipe ducting. Must be used where pipe ducts pass through unheated roof voids. Fitted with 20mm pipe connection for running off condensate. Not suitable for use with flexible ducting.) I know it says not useable for flex ducting but im sure i could fashion something. http://www.vent-axia.com/range/condensation-trap.html 4. What size extraction/intake is needed for a 1kw. I want to dial it down with a controller to make it alot more quiet. I was hoping a 6" RVK L1 (Ruck Rvk 150 - L1 = 715 m3) would be enough but have been advised it might not be enough to even properly extract the heat, never mind dial it down. So I can get an intake no problem. Should I get the 6 inch A1 (Ruck Rvk 150 - A1 = 470 m3) for intake? Would that be correct and would it be enough to dial it down but not be too much so that it will be dialled down too much during winter etc? I could get the 8" RVK (1000 cfm) but i wont have the height for it or the filter in the tent i reckon so id need to vent into the room im in. Think thats all for now anyway. Cheers for any replies. Ill like all comments too :-)
  4. ok so i just had to chop a great plant due to mold but one thing i noticed when growing it was that every morning she had water under all of her leaves, im pretty sure this caused the mold so if anyone could give any more in-sight on this strange water-under leaves in the morning occurrence and how to stop it, it would be appreciated peace
