dialling your flower room for all seasons…it took me ages to get the room that worked and engaged with my home enviroment(no pets no smoking)and no central heating in both adjacent flower and vegg rooms all year round…I know the sways in temp in the highest of summers here and the lowest temps in winter and once I had a gathering of what my home temps were; I worked a room around this…I have tested and grown some of the best weed on earth in this room believe it or not…a m3 6ft 400hps masterpiece…lolol…pic 1 is half of the magic involved…I have a osc fan placed directly in far left corner running constantly 24/7…this runs direct path over the extremely hot 400hps and makes the tube hand hot…the warm air is fluted down the light shade and gets sucked virtually instantly away into the rhino pro carbon filter…the ram inline fan is running 200 cfm and ducting straight out a wall vent in a small room with no windows(boiler room)I have complete control over the radiant heat and can explore going a little higher in plant size if needed…pic 2 is the intakes…I never run passive anymore…mechanical intakes that are tuned and set with your inline fan with reverse pressure have fruited bigger yields after trying the 2…I won’t go back!!..2 sunon 2.6w 55cfm case fans are used with variable voltage controllers(in this enviroment for reverse pressure and controlled temps they are both set at 7volts)…provides ample airflow into the grow,its screened and light leak shielded from the outside and they stay consistent and are cheap to run…
this whole mini set up is just controlled settings dialled to every eventuality in temp and humidity swings in my home throughout the year…less than a foot away from light in the highest of summers I’ve never once reached 30 degs.
…plants sit in high sunshine and stable warming heat with adequate extraction and intake and simply fly…flower lights 12/12 I turn on at 7pm when my sun’s on the turn outside and off at 7am when the sun starts it stretch…and I will convert a led lover over to hps when you see the system in action…a m3 400w hps mover and shaker has entered the building…
and a late edit…I read many years ago that the sun in its highest form of the day emits 56,000 lumens per square metre onto earth surface so I went with science and its true…you create a version of the sun with correct par lighting in a m3 space with simply a 400w hps…anything more than that and it’s straight overkill even if you contain heat…I’ve tried the process yrs ago thinking I was slick with a 600 in that area…nope…light pollution gave off the distinct “look like I need feeding but I don’t” syndrome…it wreaked havoc …when I went back to the science I found the 400w and 56.000 lumens in m3 held everything together perfectly…light pollution a thing of the past…and you might think I sound mental or need some kind of check from the neck but I studied the area I had and what produced the best with Ltd heat in this enviroment…this system was it…end of mental ramblings…lolololol
