About Solutions -- Dissolved Oxygen in Hydroponics http://www.grozine.com/2014/01/31/dissolved-oxygen-in-hydroponics/

Grozine says, “Dissolved Oxygen in Hydroponics is that missing link to faster growth rates, healthier plants and even bigger yields. Dissolved Oxygen in Hydroponics is that missing link to faster growth rates, healthier plants and even bigger yields.”

Grozine also says, “Typically 16 PPM (parts per million) of DO (dissolved oxygen) at the roots is considered very good. Most healthy growing situations are probably half of that. [less than 8 ppm DO concentration – low oxygen] Double these amounts are possible with specialized technologies that actually dissolve O2 in solutions, rather than just bubble it through (diffusion).”

Now consider this as water chillers are popular when those “big boys” on this forum talk “chilled res water and those DO oxygenation issues.” Freshwater @ 32 F has a DO concentration of only 14.6 PPM DO says the DO Chart with no aerobic plants or microbes in the freshwater consuming oxygen reducing the DO sat continuously.

Of course all water chiller salesman never tells you that his DO Chart does not subtract the collective metabolic O2 uptake of all the plants and microbes in the res water from his chart. Aerobic plants and microbes do consume elemental O2 dissolved in the res water you know. More plants, more Bennies consume more DO reducing the DO Sat continuously when air pumps and air is the source gas.

If you do not actually test the DO in your res water, you do not, cannot know what your DO really is if you are not an expert that can make predictions DO Sat. from water temperature, DO Charts, many claim they can diagnose low DO problems by “reading the leaves,” guessing, hoping and praying. 99.9% of the hobby growers are steady state tense, always looking, waiting and watching for fungal infestations and those dying rhizomes every day… waiting for the fungal crisis to exhibit?

Treatment of fungal outbreaks is by far more popular and accepted than preventing the common low oxygen crisis that encourages fungal outbreaks… and this cycle often repeats crop season after season, you know how that works even when using water chillers, H2O2 and bleach.

This is why its so important to keep your temps at a constant 66-68 degrees, LIKE THIS ARTICLE STATES. This is where a thermostat, ice probe or chiller come in. Chunking in ice and etc. produces wild swings from hot to cold and vice versa. Im not a botanist by any means but common sense tells me swings are bad.

Anyway my main Rez is at a reasonable temperature and still falling. The peltier cooler seems to work.

The main problem people do not understand is that you must insulate whatever it is you want cooled down, this goes for just about everything. I have seen so many people complain about it not working when they just stick it in a bucket without proper insulation.

I just added an exhaust blower into the mix. Hopefully it helps with the heat buildup from the leds. My peltier gets my Rez down to 20*c no problem at night but during the day there was too much heat in the grow box air for it to work efficiently. If the exhaust blower doesn't help I'm going to upgrade my peltier heatsink to a 200w monster because the one I bought doesn't have the cooling power for those temps. We'll see what happens by the end of the day...btw I pulled my big plant this morning because it was a male...now I'm down to just the two autos which is fine by me because the other was a photo and I hadn't figured out how I was going to 12/12 it with the autos in the same box

If you think about it often enough it will happen might be best to look for a new job one not near blades of death with sticks tugging on your arm.

Its Helluva good Job for a suicidal person others not so much. One hook on the cuff and Zing your paste

Not quite big dog...there are safety features for just that reason. I don't wear long sleeves or gloves while chipping for just that reason anyway. I'm a climber so chipping is probably the safest part of my job to be honest. Because I'm in the tree usually I don't operate the chipper all that much anymore. Btw if the job wasn't so dangerous I wouldn't make as much money. That's why tree work commands such high prices and more importantly why I do it.
