"Because we only have to use a maximum of 12 plants for every 2,000 Watt's of Hortilux HPS, we don't need hydroponic MOMs that grow too fast for our needs. Because of this we use our Fox Farm Ocean Forest Soil and small CFL lights."

Sorry about that. My comprehension level on this thread is at about a 3 year old's at the moment... That being said, is there any adverse effects you have seen on mothers grown in DWC as opposed to FFOF when the mothers are trimmed and kept neat? My reasoning behind this is I LOATHE having to bring soil into my house and if I am able to put in a little maintenance to the mothers and not have to worry about any degenerative defects, then I would like to continue my mothers in DWC with my LED lighting. Thanks again for your time, and at this point, your patience.

You will be fine with RDWC MOMS. No problem.

The pot holding this plant would never dry...wet/wet watering caused a different bud structure. More foxy, less dense...and wen you spread her ass open she's dripping with fuel! Very peace
With regular wet/dry feedings she takes a more typical shape...towering over 6ft bamboos!!

im in loooooooove with this thread!!!
I just inquired about the neoprene washers part #420 @ www.RootdownHydroponics.com They quoted .75 apiece which doesn't sound bad. They had less than 50 left and were expecting a big order of 1,000 or so in about a week. Rep said they're surprised about the big demand for them. Maybe a bigger hydro company or retailer is up to something or just a lot of smart gardeners like us.
My “educated guess” as to the nominal OD or thread diameter for Sched 40 pvc 1.5” diameter pipe from Flexible & Rigid PVC Pipe Size Dimensions & Pressure Ratings is 1.9" ID or 1 7/8" for the washer needed.
I know a good price for 3/4" hose washers @ $.10 apiece (Irrigation Direct. $.04 - .08 in bulk) and I'm guessing the amount of rubber used (neoprene isn't cheap either) for 1 7/8" ID washers is at least 2x2x2 (lxwxd) or about 8X as much rubber as the 3/4" washer. Maybe more like 12x as much rubber...
A similar size from Lowes is $1.98: 2-15/16" OD x 1-7/8" ID 3/8" thick

I am wondering if it's possible to use a simple chlorine meter used for pool maintenance of the 50 dollar one from Hanna in order to maintain my chlorine levels.
I can guarantee you that all the washers that were sold went to IC members because IC is the only place that knows about this washer. This makes me very happy! I just hope some threads pop up of members running the system.
I would say yes as long as it can measure 0.50 ppm.

Something like this is what I was thinking. Seems simple.

Yeah that will work just fine! Every hydro grower should have a Chlorine meter. Youd be amazed what your chlorine levels tell you when you get used to how much you should be losing every day in your specific systems.

I probably missed this, but @ .50 ppm chlorine, how much should I be losing per day and when should I "top up" my chlorine?
Our conditions will not be the same. Because of this you have to keep notes every 12 or 24 hours on multiple systems or multiple crops and compare your notes and you will find out. When you are battling a pathogen, your chlorine will leave faster. Temperature and air may also play a role so you need multiple variables in your notes. Data is the answer to everything.
Keeping res temps @ 68-72 F helps big time with controlling pathogens (some go as low as 65 F). I used to brush off idea of chillers but they solve many grower's problems that get reported. $2-300 each for my in-line chillers for veg & flower if not a necessity a great investment if your water temps are aroud mid 70's or higher. Jugs of ice work good but eventually become a pain after a while to change out so many times/day.
Also helps with DO holding capacity so your aeration is more efficient. I keep all pumps outside res (inline instead of submersible) to help control heat.
Ty a search on flooming without airstones. Airstones have advantages but also add heat (unless air pump located outside). Also DO & top drip hydroton.
But my advice is to get a chiller if your water temps are up there, does many things @ once.
Like I said before, i dont use chillers in any of my systems and never have crop failures with the use of chlorine and lots of air. Chillers take up a lot of watts that I use for additional lights and systems. Ive run my RDWC systems in the low 90's with no problems and still get at least 2 pounds per light.
As a word of caution... If your water temperature pushes into the 100's, the proteins the roots are composed of will begin to denature. I only mention it b/c low 90's isn't that far from low 100's. I'm sure you're on top of this... but readers should know res temps do matter even when running a dead res.
