Yep. The sanlight dimmer is a manual operation. You can have them set at X% and they stay there unless you actually go to the light fixture and change the setting. Also the sunrise/sunset feature is over 5 minutes. I wish to have the sunrise and sunset over perhaps 30m-1h. The third reason being...

Pumps.. don't forget the backup for your backup ;)

Out of interest, what made you choose Scyence?

OK I've never done a grow that big but if I was going to I would want to keep everything as simple as possible in the initial stages. F+D is just that. You don't have any problems with distributing the solution if you use multiple connections. It's super easy to clean afterwards, there are no...

You used to do soil right? My advice would to be get some plants growing in soil where you are happy. In the mean time, sterilise the shit out of everything in your hydro setup and then when you get to it, clone from the soil grown plants and place clones in your aero system. Trying to figure...

You could switch to an external pump if you are worried about the water temperature. Airpumps shouldn't affect it, but a submerged water pump is a lot more heat than most people realise.

I used to use a float valve on my res hooked up to an RO machine but never thought to add a timer to it. I just relied on the fact my plants would drink more in the feed than the RO would supply in the same time :wall: Fortunately I never had any accidents! The float wasn't right at the top of...

I would run my lights off it, tube heaters, 2 fans and 2 dehumidifiers. Knowing that I have the functionality though, I'd look to add in a fire suppression system just for peace of mind. If it can give me sunrise and sunset aswell as autodim and fan ramp up if things get too hot, it's everything...

"... apparently that brand is a classic around here ... Any special model? .... is to compare it with other possible models of other possible controllers that I see or will see ..." Not sure what that means... :)

I'm thinking foward compatibility. Yeah the Q's are small, but you can daisy chain them and you can position them for maximum efficiency. I want to replace my 375w samsungs with q'5s so ill run about the same wattage, 4x205w in a 2x1.2m footprint, which is what they recommend at Sanlight. The...

A few things. If you've been using the wrong feed, or had pH problems, or ppm problems, or anything.. you need to FLUSH. It is absolutely no good just changing the res without a flush, because all the compounds locked in the roots will just stay there. Give them a 24hr flush of pH adjusted...

I use guardians in the flower room because I want to keep a keen eye on them at that point, for everything else, I have a handful of cheapo pH meters which I just chuck out every few months and a bluelab truncheon for PPM. I've never found the use for a doser/controller. That's something you...

Guardians FTW!

You don't need your meter to be calibrated to know you are underfeeding. PPM fall, underfed. PPM rise, overfed. Unless it is wild swinging in which case you have buildup/lockout. Same as you don't really need to do what the bottle says, on anything. Half everything it says on a bottle and...

Ahh the previous model is only 1/5th the price. That's more like it. I'll work towards the pro! Cheers :)

I absolutely do want a Trolmaster setup, because I'm a geek for automation and gadgets.. However, seeing as I could buy another 6 sanlights for the price of a Trolmaster, I don't know I can pull the trigger on that one!

LED fam, Does anyone know of a controller that works with the Sanlight Q series? Sunrise/sunset , auto dim at X, auto cuttoff at Y, and preferably will control fans as well. It can be a unit or an app/software. It seems like just about every lighting manufacturer out there has one apart...

Oooh.. Schwazzing...

Hey, has anyone used one of the water cooled climate control units. Basically an air conditioning / heating / dehumidifier / filter unit all in one, but it doesn't need an external part, just a drain. Which brands have you used? Were they any good? I'm after going fully sealed but I don't want...

It's clearly Calcium and Magnesium deficiency. Leaf edges curling up is Mg and the spots are Ca. It's point number one in any deficiency or plant diagnoses guide. Something splashed on them... jesus.
