water temps & oxygenation level,.. lets hypothesize

[maryjanesjungle]

I've been pondering water temps and oxygenation levels of late with the new grow box im designing. From this point on in the conversation id like it if we could all forget the normal ways of growing we've seen and just hypothesize about the following two ideas for a minute.

Scenario 1:
the roots would slowly move, and enter unoxygenated and uncooled room temperature water 3 times a minute for a few seconds each pass, and the rest of the time be moving very slowly exposed to room temperature air. Wouldn't this give the roots food, time to breath, and also cool them below room temperature same as your hands feel cool as you reach for a towel after removing them from water?
This idea is basically eb & flow but the plant moves,.. very much like these rotating garden
Do they chill and oxygenated there reservoirs? (for the dang price they ought to jerk you off!)

Scenario 2:
unoxygenated and room temp (mid 70's lets say) water are sprayed onto the roots. Wouldn't this give the roots food, time to breath, and also cool them below room temperature as well? On a side note this scenario would in some way oxygenate the water not unlike a small water fall does in nature.
This idea i basically aeroponics without chillers or oxygenation. Are they really needed? I know your instinct is to say yes because that's what everyone does but in both scenarios the roots are given food, air, and water.

They need nothing more then those 3 things but are the delivery methods i outline above how the roots can adequately use food, air, and water?

What hypothesize you?

interesting find,.. but we don't know if the water they use is cooled or oxygenated

O levels are dictated by temperatures. If water is too warm the lack of O will be very apparent, I know you are challenging common use but its there for a reason. You will need to keep your rez temps low enough(65-70F) to absorb max O (aprox 6%) if you don't you are asking for problems.

No offense but you didn't really read, or at best get, either of my scenarios, and i base that statement on the fact that you didn't address either.

I dis-agree both scenarios will be minimal at best. The room un o'ed water is similar to drowning them but only for short periods, sort of a "waterboard" for plants, lol. Why not lower the temps? O rates dramatically increase and with the same methods would be more productive.

I hear what you're saying, actually we've all heard what you're saying before a lot, but i question it and i think you're missing the point still,.. well actually i know you're wrong since im doing one of the two senerios above and its working quite well,.. well now that the plant has recovered from one really dumb idea that almost killed it a week ago

Below is a pic of the root growth im getting from non oxygenated un-cooler mid 70 degree 250ppm 5.8pH res water,.. a res that's less then a gallon of volume at that.

Those chunks of rockwool are what is rotating in said water,.. actually the roots arent even touching the water,.. yet,.. they will once they get longer

It's not like drowning a plant but only for short periods of time because for a few seconds those roots are in the before mentioned res water, say 5 seconds, then not for say 15 seconds,.. roughly, i haven't timed my device that closely, but none the less when there not in the, "toxic" water as u make it sound, there getting the air they need, when there not getting air there getting fed. We'll see what kinda plant/yield i get in a few weeks but its surely not being killed slowly.

Gere's a pic of the plant responsible for those awesomely fuzzy aeroponic like roots.. it be an auto white russian, lowlife seed

I can give you a prediction but you'll have to try it yourself to find out for sure.

Once your plant reaches max flowering growth or before, the plant will no longer be able to absorb enough oxygen through the roots. You may or may not end up with root rot at that point.
Try it and see.

Yes, an Ebb&Flow setup does this much better and creates a very richly oxygenated, dark and highly humid zone for the roots to grow.

Scenario 2:
unoxygenated and room temp (mid 70's lets say) water are sprayed onto the roots. Wouldn't this give the roots food, time to breath, and also cool them below room temperature as well? On a side note this scenario would in some way oxygenate the water not unlike a small water fall does in nature.

Yes, this is basically aeroponics.
Read up on it and you'll be able to make your own decision.

I don't get why such negative prognoses and lack of even talking outside the box about a plants roots maybe just maybe having the ability to take oxygen directly from the air. You make it sound like an mj plant can ONLY get oxygen from water it drinks that happen to have oxygen in it. How do mj roots 3 foot deep in hard dirt breath then? Do they too only get oxygen every few days when you water them and the rest of the time there being suficated,.. or dirtboarded? LOL Both scenarios i speak of are hardly DWC minus air pumps and chillers. You say its like eb and aero but that it wont work, i don't get why.

Well either way im documenting it all with pics and videos so IF its a female well see in ummm 8 weeks how good it works? That's how long it says this plant should take from seed to harvest,.. ill give it a bit longer based on all the beating i gave it early in life though,.. replanted it 3 times before i got it right.

You keep saying to discuss like 'talking outside the box' but you read what we type and take it personally. Nobody is attacking you.

I'm talking 'hypothetically' based on personal experience with roots, water and oxygen. Keep experimenting and you'll form your own opinion based on your own observation.

There are so many "proven" research studies on root oxygenation that you could save some time checking them out. The proof you offer isn't really, you have a lower temp water, 70ish you say, and smaller plants as mentioned don't have as high a demand for any elements. Seems like a lot of hassle but its your time and effort. There are DIY chillers too. But once warmer temps arrive and plants are sizable see what you get, compared to whats been proven.
