The Grodan 40mm cubes I use have a plastic wrapper. The cubes are supplied bonded in sticks of 15 with a strip of paper which is glued to the plastic wrapper on each cube, so they can be broken off the stick of 15 one by one. I leave it on to reduce evaporation losses from the cube. The wrapper keeps the sides of the cubes wet- if it were not there, the roots would not form as readily on the side surfaces of the cube as it would be dryer.Why do you leave the paper on your rockwool cubes does this do something I know nothing about.
serpentine describes the snake-like path of air through the trap, not the colour...And what color is serpentine never heard of it
I believe I said to paint the interior of the trap with flat BLACK paint, didn't I? Black will tend to absorb the light as it bounces through the serpentine light trap. White paint will reflect light, helping conduct it through the serpentine path... and will defeat the purpose.I have some flat white paint that I used on my closet doors is this good enough?
Depends on how big the fan or duct feeding it is.And last but not least how big do I make the light trap outer dimension and I can figure out the rest.
Interesting idea, though pretty bodgy. I don't think you need to cut up a cooler to do this, though. You could simply direct a circ fan to blow air over a frozen plastic jug of water and you would get some cooling of the air. I disagree that this would raise humidity; it would actually lower humidity as water would condense out of the air passing over the cold plastic surface and drip off, like it does on the cold coil of an aircon unit. You'd forever be refreezing water jugs. Sounds like a pain.He said take a large cooler cut holes on both ends and fill with frozen milk bottles with a fan and it will cool down the grow room but another guy pointed out that this would raise the humidity quite a bit so I trashed that idea.
Good suggestion. This is the reason why you have a separate ballast as opposed to a light fixture which combines ballast & reflector.Also someone told me not to have my ballast in my grow room because of the heat it lets out.
Glad that remoting your ballast outside the room helped.I took the ballast out and I believe my temps are just right know probably between 75 and 80 degrees I think it droped the heat at least 10 degrees so I am very happy about that.
If you don't have a peak-memory thermometer, get one. You need to knwo, not guess, the actual temperature in teh grow. Peak-mem storage means you can see the max high & low temps since the last memory reset. No guessing- you'll know what your temp range is.
