My tap water is 150ppm I was doing coco my last grow with an nutrients and had big problem I just couldn't get it right bit I the it mite of been the seed I had
I do soil now and organic nutrients as it's harder to get nutrient burn
I tried everything to cool it down mine I haven't got a window to get cool air from and I definitely was not going to pay silly money for a ac unit
I had a look on you tube and only thing I could find was some one pulled the led apart and turned the fans upside down.
All I did was got some...
Your tent is bigger than mine but if is gets high you can add co2 to it
Co2 will allow you to rum at a higher temperature you can get co2 fr9 your local hydroponics store £££ or you can make your own for next to nothing it shows you how to do it on you tube all you need is sugar and yeast
Tells you the ec/ppm of your nutrient feed after you mix the all in your water.
If the ppm is to high you can run in to nutrient burn, nutrient lock out
Stops the hot air coming out the side of the Led's and take it straight out out the tent you can get them for the hps lights but carnt for led's so I had to make my own
I have mars 600w aswell but in a 2x2 tent and it got up to 30C so had to make a cool tube for it lol its works got temp down to 21C just in time for flower
