Low Pressure Aero build...it has begun!

[diggs99]

Same shit different pile...calcium hypochlorite

Thats good to know, thanks

Would this be diluted and mixed at the same ratios as shock? Thats why i went looking for shock specifically, i seen a few threads where growers had already done all the math on mixing batches . Im not smart enough to figure it out myself lol

This ,one gram does like a million gallons.

lol, nice

 

[myke]

Haha. Renfro will know. Something like a tenth of a gram per 10 gallons. Idk

 

[myke]

Like you have to count the grains I think. Need a very accurate scale.

Yes 1mg/L =1ppm. I normally dose at 2ppm but you could go higher if needed. Tap water can be up to 5ppm.

the math for dosing 100 gallons, 378 liters
.378 x 2 = .756mg then divide by concentration, usually 65% but it will be listed on the bag. So .756/.65 =1.16 grams, call it 1.2
Ya you need a pretty accurate scale...

Also, once you've weighed out the granules, add it to a shot glass of warm water to make sure they fully dissolve, then add that to your system/res.

So 1.2g per 100 gallons?

 

[myke]

so 1 bag 454g does 37,800 gallons.so my 25 g system does 1512 rez changes.2 weeks say thats 58 years worth.edit........ no guarantee on math

For my 30gal res I use .3g of shock. I've been told .1g for every 10gallons gives 1ppm of chlorine

Ya my res is only gonna holds 40g, i should be good for a few crops per 454g bag lol

I keep going back and forth on what to do with runoff. Part of me wants this first run to be as problem free as possible and figure just allowing the runoff to drain to waste would be smart. The other side of me says why waste water and nutes, run it back to the res and reuse.

I planned to put res under the table and just allow gravity to feed runoff back to the res. Not sure how to place the drain to ensure all water drains off, it seems no matter where i put it, theres gonna be a bit left in the bottom somewhere. Maybe im overthinking it and its no biggie either way in aero and sterile.

Im hoping to start putting things together within the next day or two. I am doing some work in my room( building a new table, running more fans and new filters etc) The plants are doing well and should be ready to start taking clones within a couple weeks.

I have all the parts for the plumbing, minus 2 ball valves that im waiting on, they said they would be in this week. Ill check with them tomorrow.

So..... we are back to. Ditch lpa go rdwc. Like we said 10 days ago. Go rdwc go rdwc. Lol.

 

[Axion42]

I agree Diggs ^^

 

[ToFarGone]

you said you don’t know what to do with runoff? Just let it drain back to the res. Your doing water chnages every 2 weeks I’m sure I read so you won’t create that much of an imbalance in 2 weeks of any.

If your doing drain to waste and not recirculating or reusing runoff. No need to change the res every 2 weeks. Just make sure the res water is agiltaged to keep all the nutes mixed in

there is no sense in draining to waste with that setup. a little bit of water left in the tote is not a problem, even if you werent running sterile. it wont sit still long enough to cause any issues

Thanks for clarifying, as i said, prob just baked and overthinking it lol

So..... we are back to. Ditch lpa go rdwc. Like we said 10 days ago. Go rdwc go rdwc. Lol.

Nah, not even close to making that decision, as i told you 10 days ago....i want to try aero....this was just me being guilty of overthinking shit from time to time lol...i do that

When you combine sprayers in a tote and recirculation isnt it just rdwc anyway?The way people have designed their waterfalls its really only the water level thats different.

well not really as the roots shouldnt be submersed in water with the aero sprayers and runoff going back to the res. RDWC roots are always in water arent they?

Yes ,I guess theres a big difference.So theres no water at all in the bottom of the tote?

 

[diggs99]

No, there shouldnt be much water in the totes once runoff drains off. There will always be a little ofcourse, the stuff that cant get to the drain, but shouldnt be very much.



Im trying to figure out the runoff getting back to res now, originally i planned to put the res directly under the tables and just let gravity do its thing, my issue with this is height, the 50g res is 18" tall, if i put it under the table, then add another 16" for the plant totes+3-4" for the table, another 18-24" for the plants, im at 62" in height, that leaves me only 34" for lights. Its doable as i run my lights very close to the tops of my plants but it dont seem like its gonna be practical or overly comfortable for gardening.


Im considering a few options:

Use smaller totes for the plants, the 15g totes are only 11.5" , so that would gain back 5-6".....i already have top holes drilled in the 27gs but thats no big deal, i can easily find use for them elsewhere lol

Using a Lower profile res(10-12" in height) ill buy it if i can or build it if i must. I can buy 15g tote thats 11.5" tall , just not sure if its big enough tbh, other option is build one the exact size i want and line it with pond liner ala @Renfro )

Using a small low profile collection bin for the runoff with a small pump and float valve on synced timer pushing it back to the res, this way i can place my res at the end of the room and gain back some of height. This seems like a bunch more work not sure its worth the effort. I do think having res at the end would be better in my room, so thats a plus.
