Go on that vacation....Your ph is perfect!!

I just found this nifty little thing if your willing to drop $200 on it, but to a lot of us hydro people that aint shit. It looks easy to use with two set points for your high and low ph ranges and two 110 AV outlets on the top. plug one pump into the first outlet for a base rez and one pump into the second outlet for and acid rez, hook them seperately to two flow conrol drippers which will drip every every 5-10 seconds when activated by the controller. Place these above your water level and its like your sitting there adjusting the ph yourself. Get a gravity rez and you may never have to go in your grow room again. Peace
Heres the linkPinpoint pH and ORP Controllers

Heres the manual for the PH controllerWelcome to American Marine Inc.

Looks like you set one desired level for your ph and it has a range of how far it can move away from that level before dosing either up or down.

Update on the price. The ph probe is sold seperately for 44.99 and the AC adapter is 9.99 if you dont want to use 9 volts. All together your looking at around 300 dollars for the doser with pumps, acid and base containers and tubing. This doesn't include the pH up and down either. Peace

It seems like you could make a simple one of your own if you know how work with little electronics. Just get a probe for $50, then change it somehow so when it hits 5.6, the alkaline pump goes on, and when it hits 6.1, the acid pump goes on.

im a dumbass, it does come with a probe. sorry guys

I couldnt do that. But who knows.....

No offense Dr. H, but I could have a rolls royce too if I could make one. It's the MAKING one part....

LoL, Dr. Hashman. Why don't you make me a digi ballast while your at it. I also was looking for a Flux Capacitor.

Well he IS a dr.....hey I'm in line for one of those flux capacitors as well!:)
