Top tip... cool your room.

My environment controller has intermittent or constant idle and cooling speeds.

Below x centigrade its slow fan speed/off and above x centigrade it kicks in at cooling speed.

I usually need it on intermittently to let heat build up but it's a balmy 16c outside so I can run it constantly atm but only slowly!

Yesterday it was 22c at the intake and I was maintaining 26.5c on the 3rd setting approx 15% of the fans power (6" systemair 680m3 iirc)
I normally use 600/660w hps and the same applies in regards to power settings, I've never required more than 50% of the fans power and considerably less when I run it constantly.

It could be the way I've my tent set up or whatever but at the end of the day all being equal a constantly running fan is much better at maintaining temperature rather than trying to fight it back down after its rises.

Who'd have thunk it ;-)

In this current U.K. weather my fan only kicks to low speed during dark hours on my SMS controller.

set to 25C.

Is your controller thermostatic during the night?

I've had a couple of other controllers, a rhino hybrid and a ecotech regular but they run away with the heat at night or buzz/humm when turned down, I can't afford noise in my situation so I made up my own hybrid with individual day/night temp and speed control, switches on/off heating/cooling equipment, in relative terms it wasn't that expensive to make considering its spec.

It’s thermo controlled regardless lol.

But with outside temps up in the mid 20’s during the day outside.

I will add 2 thoughts --

> Running the fans provides fresh CO2 so running the fan is good, I wouldn't try to not use it.

> Plants are used to cool sunrise followed by warm daylight hours followed by cooling down at night. While it is not necessary to do it this way, it's also not necessary to run at a constant temp.

When I see that cables and meters its fine tune 0,5 degrees saving 0,005€ per day spent hundred pounds and hours of work and observation just for no effect for plants. Put in on cheap constant exhaust or invest litlle in EC-TC fan or invest more in AC. Things you are doing are just dicking around and lie nto your own pocket that it works like you imagined because it cost you time and money. But it can be fun…

My basement is 60-62f year round, it's pretty chill.
Got 460w (actual) of blurples in an armoire just fine. Little 4" inline eBay fan @7w.

You have clearly missed the point, I can't fucking believe you said that lmao.

Summer/autumn/winter and spring I can control the temperature and humidity to within 0.3c.
You call it dicking around I call it making the best environment controller that money cannot possibly buy they don't exist in that spec.

You should feel a bit when I mention the two variacs incorporated...

Thanks for your thoughts man I appreciate them, it's a couple of good points I've never taken into consideration.

Just to clear I'm wasn't trying to boast about how clever my controller is I've done that hunners of times :-)

The above was how I arrived at my conclusion.
Point being if you're having trouble keeping your room cool a £10 plug in dimmer/speed controller can help you by running it constant.

B is a top grower and poster...even if it came across a little straightforward he was making a point that has merit
He wasn't though, it's the ultimate in environment controllers for a fraction of the cost of lesser hybrid controllers, to get something remotely close you're into £350.

It controls night and day temperature thermostatically at both ends, variable speed night and day, it turns on/off appliances when necessary, it's power supplies are variacs so I've control over speed at both ends without any hum/buzz 0/100%.,
So no I don't think he had a point, I've bought crap controllers for more than it cost me to make my own improved model.
I think imissed the two stage cooling.
Fwiw circa £140

I don't know what on earth brought that pathetic rant about, ime unjustified rants stem from ill feeling or jealousy?

Just incase you didn't notice... I'm offering ideas to members that I've personally tried and tested with excellent result, I could've been self centered cunt and not give a fk about others by saying nothing, maybe I've missed the point of a forum?

FYI environment is equally important as lighting, nutrient and genetics and by fuck I shouldn't need to tell you that.

Doesn't your latest tech doesn't have cables, wow that clever lmao.

I think you mistook his post entirely.

What I gathered is he thinks that you SHOULD invest in environmental controls otherwise you are dicking around turning fans and off and wasting your time/money anyhow just to save a couple cents. And he mentions at the end even though it's fun sometimes.

The dude was giving good advice. Dunno why that would piss you off.

It is for nothing unless you have AC, dehu and other stuff connected to it. You will be always depending on ambient temp and RH and those you will never beat with a fan on controlers unless you are in sealed room and it puts you back to AC and dehu and other stuff. I am in Netherlands so kinda similar climate and I am not able to handle the heat in summer on the loft even with 11kbtu portable AC. Those are for nothing since they are only single hose shits. Or maybe I can make it work but it is not worth for me. It was not meant any negative way dude, just do not see it working like you are describing. Sorry for that. Hopefully all good…
