Hydro Newb looking for help with DIY build

Yeah, saw this last page, but couldn't tease any permutation of "ecoair5" out of google or amazon. Did you mean the "EcoPlus Air 5"? If so, the reviews talk a lot about noise. You? Would you put it in a closet next to your bedroom?
Mine's called the Ecoair5 Commercial but looking at the lower rt corner their website is ecoplususa.com

Not going to want it in a closet in your bedroom. It's a commercial grade air pump so they're not concerned with noise nor am I. It's down in the dungeon with my big jet pump etc so noise is not a concern. Can't hear a thing in my mancave upstairs so not a problem. Teh damn chickens the wife has in the shop drown out all of that. :D

For the usual aquarium air pumps I hang them from a soft spring or even some of that soft silicone airline for aquariums to soften the noise from them. Sit it on a shelf and it makes a racket.

:peace:

I wear a dust mask when trimming...it helps.
I get high as a kite when trimming from the fumes. Thinking of breaking out some new hydrocarbon filters for the silicon half mask I used to have to wear all day when I worked as a chemist in a hazardous waste disposal plant. That'll take care of pot fumes no problem. :)

:peace:

What do you use/recommend now, or are you not concerned with noise?
see my DIY F & D system posted a couple pages back

I run one gph pump for flood and another for looming with a venturi. This pump is on a deep cycle timer. I run it ~ 2 minutes/~ 10 minutes.. Among the benefits are no co2 drawn into the nutes, which increases pH

You would have to pump pure CO2 through an airstone for hours to raise the pH a 10th of a point and the acid breaks down almost as fast as it's made. At 1500ppm that's only 0.15% of the air and considering ambient CO2 is 400ppm it's only being raised 0.11%. Nothing to worry about and the plants love it.

I've considered flood and drain but it doesn't fit my style or grows. I'll be running 4 very different strains at different stages of flowering to keep a perpetual grow going so 2 plants each in DWC ScroG tubs running independent of each other fits my plans a lot better. One air pump to worry about and no water pumps/timers etc suit me.

F&D works great I know but just won't fit my plans.

I am currently running 3 tents

1. F & D

2-3 are same size dwc totes
2. has 4 airstones
3. has flooming/venturi pump to circulate nutes 2/10, 24/7

I check pH daily.. 1 & 3 are fairly pH stable

The bubbler tote pH rises from 6.0 to 6.5+ /24 hours

I saw a video recently where a guy used a heated tin can nailed to the end of a stick to melt holes thru the lids to get really clean edges. Still trying to find the right sized cans to do my 3.5 and 5" net pots with. :)
You can buy a cheap set of hole saws at Princess Auto on sale for $20 lol. I've had a set for 10 years and they work well on plastic, just a thought ;).

Depends what sizes they are tho. I've got a shitload of 3.5" net pots from a buddy that had bought them for a big DWC farm he thought he'd get rich off without knowing shit about growing and wouldn't listen to anything I told him. Hasn't read book since he dropped out of school in grade 10 but knew everything. Hasn't been a buddy in 5 years. :D

I like Princess Auto. Can find all sorts of cheap stuff to use in a grow room or to tear down a grow room for that matter. :) Two hours away tho so I don't get in there unless we have to go to the city for something.

:peace:

Not sure what's in the set but it goes from 1.5 to 6", not the highest quality but works good for totes and pails. I stopped using 3.5's due to light leaks but I have large size hydroton as well which doesn't help. Never did cover them which would have worked as well lol.

Thanx, Blue. How much thin bleach and how often? For Ozone, you mean an O3 generator?
An aquarium o3 generator yeah, with bleach it totally depends on the strength you use, there’s a thread somewhere on here where the girl talks about the exact dosage for different types of bleach, I suggest reading that, that’s what I used to work out my ml/litre, depending what bleach you use yours could be 10x or a 10th of mine

Okay, finally. So, the hydro tank has been designed and built, and actually turned out pretty good:

IMG_20180118_192448958_HDR.jpg

The double walls are composed of 1/2" plywood on the inside lined with plastic shower stall material from Home Depot, and 1/4" veneer on the outside. Between is 1/2" of Styrofoam insulation. Inside corners are rounded off with 45' inserts to ease cleaning.

I have a commercial air pump -- damn those things are noisy and hot -- and a 4" airstone below each airpot. The 5-inch net pots give some idea of the scale, but with the water level at 1.5" below the bottom of the pots gives me 26 gallons. A lot of water, I know, but it should give me more stability in pH and fewer solution changes.

I also installed 1/2" sprinkler pipe inside the tank attached to a 390 GPH submersible water pump with 1/4" lines that go to each pot with a small sprinkler head on the end. The pump runs 1 minute on, 9 minutes off.

I'd like to follow @OldMedUser's schedule and change the tank only 2-3 times during a grow cycle, but I want to use tap water and ours carries ~60 PPM of dissolved "stuff." Will that be a problem as I top off the res with the same tap water, adding more "stuff" every time?

So I'm ready for some plants. How developed should the roots be on clones before putting them into the hydro pots?

The 60ppm of dissolved stuff in your tap water will do absolutely zero harm to your plants. Others will disagree with that but when asked to prove it they wont be able to.

Build looks great well done!

Your water will be fine imo. As for changing out the res water, lots don't and follow a modified Lucas formula add back, for the money it costs me, I Change out res when it needs refilling as I seem to get more stability with PH
