cool, thanks Moe! you had told me you liked 3-1/2".. i couldn't find that size so i bought some four inch trade size and the actual is almost 3-1/2"

this size is going to fine, correct? btw, i'm gonna steal your twist lock idea, i expect a patent lawsuit!! hahaha

Yes those will work. You might have to modify the opening a slight bit but I’ll give you the designs in whatever format you want so you can match your cups.

I highly recommend PETG for these. Pla is not strong enough.

Can't get this shit off my mind lol

Just wanted to see, 1 disc will probably work for an 18gal tote.

1 disc will work for 55 gals. 9 discs work for 20 gal.

It all comes down to timings maint and water temps and what you are willing to work with.

There is a sweet spot imo. I have smaller and larger and settled on 5 disc for 55 gals as the best overall compromise. Water stays cool fan need is minimal and I can get away with cleaning once a month. With a single disc plan on weekly cleaning. Also your on time will be much higher

Oxygenation and its influence on crops
Although some contradictory results have been reported regarding the use of methods to enrich the growth medium of crops with oxygen, especially with uncontrolled environment conditions (Urrestarazu and Mazuela, 2005; Bonachela et al., 2007), various experiments with production of plants under greenhouse, either in nutrient solution or in substrate, indicate that high levels of oxygenation they accelerate development and increase yields, as a result of the improvement in anatomical-physiological processes and increase in the hydraulic conductivity of the roots, greater mineral absorption and more efficient photosynthesis (Urrestarazu et al., 2006).
Morard et al. (2000) reported in melon (Cucumis melo L.), with a radical development of 25 g L-1 and nutrient solution at 20 °C, that the saturation concentration of 8 mg L-1 is reduced to 0 mg L-1 in 60 min, if there is no oxygen replenishment. The oxygen supply in rose (Rosa sp.) Increased the activity of the enzyme alcohol dehydrogenase (ADH), improved the growth and development of roots and stems. In tomato (Solanum lycopersicum L.).
Experiments by Goorahoo et al. (2002) with drip tape 12-15 cm deep and studies by Bhattarai et al. (2006) with tape at 8 to 30 cm depth, showed the benefits of oxygenation. The data showed that the increase in yield of pepper fruit (Capsicum annuum L.) reached its maximum value at 25 m from the aeration source and then decreased over 35 m, equaling the yield of the pitches without aeration.
In oxygenation tests with air injection with venturi and hydrogen peroxide in a clay soil cultivated with tomato, soybean (Glycine maxL.) and cotton (Gosipium irsutum L.), yield increases of 12, 84 and 21% were obtained , respectively, compared to the control (Bhattarai et al., 2006). Similarly, in clay and sandy loam soil, venturi oxygenation produced an increase of 33 and 39%, respectively, in the total weight of pepper fruit (Goorahoo et al., 2002).
Soy adapted to prolonged oxygen deficiency producing adventitious roots, the stem showed hypertrophy and developed an aerenchyma for the transport of O2 to the roots (Boru et al., 2003). The efficiency of the use of water (EUA) with oxygenation was 11% higher (39.1 versus 35.2 g L-1) for tomato, 70% (3.65 versus 2.15 g L-1) for soybeans and 18% (0.45 versus 0.38 g L-1) for cotton in a clay soil (Bhattarai et al., 2006) and 36% (1.46 versus 0.94 kg m-3) for corn in a clay-sandy loam soil (Abuarab et al., 2012).
Other EUA effects, such as the photosynthesis/net leaf transpiration ratio, were also greater with oxygenation (Bhattarai et al., 2006). Urrestarazu and Mazuela (2005) supplied O2 with potassium peroxide (1 g L-1) to pepper and melon, finding a yield of 20 and 15% higher, respectively, with oxygenation; but there were no significant differences in cucumber.
In this regard, Urrestarazu et al. (2006) indicate that the application of a chemical oxygenator to the irrigation solution significantly increases the availability of O2, translating into higher fruit yield per plant. Underground irrigation with 12% air in the water, stimulated growth and improved reproductive performance by advancing flowering and fruiting in tomatoes, and increased yield by 21%, the effect of aeration was greater in soil at field capacity (CC) in relation to the soil with water stress; while in saline soil, the increase was 38% in relation to the soil without aeration.
In both cases, the efficiency of water use increased, 16% in humidity experiments and 32% in salinity. The increase in yield with aeration was also accompanied by a higher harvest index (IC), higher fruit weight, and a lower water stress index. The benefit obtained by the oxygenation of the irrigation water was not only observed in conditions in which the air porosity was low (sodium soils with poor structure or at CC in clay soils), but also in soils with less moisture availability.
CC irrigation in clay soil generated a lower concentration of O2 in the rhizosphere, but aeration improved the concentration of dissolved O2 and increased tomato yield, since aeration avoided hypoxia (Bhattarai et al., 2006). Another study by Bonachela et al. (2007)demonstrated that oxygenation of the substrate solution in pepper and tomato cultivation avoided hypoxic conditions, while O2deficiencies occurred in melon during the second half of the cultivation cycle, when high environmental temperatures occurred and the plant had developed its radical system and complete canopy.
In rose plants that received oxifertigation treatments, the leaf area, the dry weight of leaves and flowers were higher, especially in those that grew on fine particle substrates with the presence of hypoxia (Carazo et al., 2008). In these periods, enriching the nutrient solution provided with O2, by managing irrigation rafts or artificial contributions of O2, can improve crop growth conditions and consequently their productivity (Bonachela et al., 2008).
In the arugula culture (Eruca sativa Mill), different doses of peroxyacetic acid (CH3CO3H) were evaluated in the nutritive solution, determining that 40 mg L-1 produced higher yield compared to plants grown in perlite without addition of this acid (Carrasco et al., 2010). In the parameters of fertigation, production and quality of melon fruits, the application of the oxygenating potassium peroxide increased the absorption and the efficiency of water use in terms of kilograms produced per liter of water consumed.
There were no differences in fruit yield and quality, which was attributed to the absence of O2 deficiency in the control treatment and to periods of hypoxia of insufficient intensity or duration to significantly affect productivity (Mazuela, 2010). With the injection of air in subsurface drip irrigation, potato productivity increased, the yield was 27.11 and 17.8%. Also, it was higher in the air injection treatment, compared to drip irrigation (RG) and underground drip irrigation (RGS), respectively, in the first cycle, but it was 38.2 and 7.66% higher than RG and RGS, respectively, in the second cycle. In the air injection treatment, compared to the treatments without aeration (RG) and (RGS), the efficient use of water (UEA) was 46.41 and 30.52% higher in the first cycle, and was 61.78 and 19.33% higher than in RG and RGS, respectively, for the second cycle.
The plant height was 14.7 and 6.07% higher in the air injection treatment than in the control (RG) and (RGS), respectively, for the first cycle, while it was 14.13 and 9.7% higher than in the controls in the second cycle. The weight of the shoots per plant was 14.8 and 4.61% higher in the air treatment than in RG and RGS, respectively, for the first cycle, while it was 37.6 and 1.94% higher for the second cycle.
These data indicate that potato yield can be improved in underground drip irrigation if the water is aerated (Mohamed et al., 2014). Carazo (2015) reported that oxy-irrigation favored productivity in rose (number of flowers, number and weight of fruits), quality (weight and length of cut flower, duration of cut flower, weight and leaf and root surface of cuttings, rooted seedling) and development in various aspects (biometric parameters, mineral content).
When air is injected into the water within the root zone, the diffusion of ethylene and carbon dioxide outside the rhizosphere increases, leading to better plant growth conditions. Increased yields and potential improvement in soil quality associated with aeration of the root zone implies the adoption of air injection technology in the irrigation system as a tool to increase crop productivity (Mohamed et al., 2014).

As much as 86% increase in yields due to o2 supplementation. Wow.

Can you think of anything I’m missing on this run? I’m going to switch over to nute solution and get Bennie’s going today. Germed seeds yesterday. I’m going direct from germinator to this system in a couple days.

After the first node on the last plant I may switch to flower. Veg stage is bonkers with high o2. My last grow got away from me lol. A bit like getting on a crotch rocket with no experience and immediately flipping it.

Nope just going to be a challenge trying to chase the shifting limitations of growth caused increased o2.

Eg how much is does it increase the benefit of even higher co2, how many more photons can the plants handle from increased light, etc ect.

Basically a bunch of prior guidlines and limitations are about to go out the window with increased o2 and finding the new ceilings will be the challenge to answering what is the increase in growth.

I think this will take several grows to determine before a definite or close to definitive answer will appear.

Remember that all these limiting growtg factors work together so changing one changes them all in a sense.

Based on my research i would say its not unlikely after removing the limiting factor of o2 and adjusting the other factors to their new ceilings that over a 100% increase in growth may be possible and even likely when compared to growth without manipulation of o2 and co2.

Specifically the combination of o2 and co2 will compound with eachother. Eg co2 shows an increase of around 30% is possible. But now with o2 i would say its would have a similar possibility of about 30% increase in growth. But combined would not be a 60% max potential increase but rather compounding with eachother to give 100% or more if all factors have been adjusted to their limitations
 
Even factors like temperature i believe will be key. Higher temps increase metabolic rates when i ran o2 my nutrient solution was in the 80’s and i can’t say it was ideal but without o2 i can say it would have been detrimental.

In fog with o2 80F may well be the new ideal temperature among higher co2 , higher ppfd,

The one factor i don’t see changing much is nutrient concentration or ratios. While i can promise you will see an increase in transpiration. If anything a slightly lower concentration may be beneficial as transpiration increases greatly but so does growth so the demand for nutrients increase but this will be addressed through increased nutrient uptake from increased transpiration

A vicious cycle lol
 
Just to quickly discuss the over 80% increase shown in the study there is a reason for that. The type of media it is applied to. Say in compact soil you may see a 80-100% increase in growth rates but in hydro maybe only 30% this is because of the o2 limitations of the media for o2 concentration and gas exchange to begin with so its important to understand this when determining how much of an increase people may see for growth.

Basically the soil went from o2 levels of dense soil to o2 levels at or above atmospheric.

So basically the higher o2 levels the base media maintains naturally the less increase in growth we will see. Fog and Aero seeing the least increases due to their high o2 to begin with.

I have also come up with a way to inject o2 into all other media like soil coco etc but it does take some engineering and modification of what we do now.

That was my hypothesis early on too. But it seemed like the overall EC needed to be higher in fog. I'll document this clearly and see what we learn.
