Evaperation

Humidity gets a bit low so used a few trays with carbonated water to evaporate for more humidity and some extra co2. The leaves feel much softer and more silky as a result.

Was wondering if you can also add a little of the left over feeds to the mix and if the neut evaporation will be used by foliage or just dry and stick to the trays like salt does?.

The nutes would leave a thick residue on the tray most likely. As far as carbonated water goes for co2, it would have to be above the plants considering co2 is heavier than.air and sinks to the bottom of an area.
If you decide to put the tray up high make sure it can't ever spill on.anything electrical.

So are no nutritional particles able to go airborne during evaporation, or are useful in a gas state even if?.

I done a quick check and found this article claiming heavier gases will spread, rise and occupy the entire area over time.

Over time in an enclosed space with little circulation maybe yes. But think of your exhaust fans that are sucking it all out and bringing in new air to replace it. I doubt that evaporating carbonated water in.a tray would even get you to a ppm level that would make a difference anyway. Not to say it is impossible but you would need to be evaporating a hell of a lot of it.

The priority was humidity level. The extractor is up a height with trays below foliage level, If I read correct leaves take in co2 from the underside so any evaporation is forced up through being why I decided to use co2 water to double bonus humid/co2. The question I asked was if adding left over neuts to the trays would be in any way beneficial as an addition to the above.

If you don't have an answer to it that is fine, It's tale chasing when people create problems from questions that were never asked though.

I already gave my opinion that it wouldn't be beneficial to add nutes to it. It will be a breeding ground for bacteria.

As for the co2 uptake think of how people add co2 in closed environments, they disperse it at the top of the room to bathe the plants it. If the air around the plants is chock full o co2 the plants will have no problem breathing it in as the air passes around the leaves. But there has to.be enough co2 in the air to make a difference, in the case of the carbonated water I don't think that it generates enough to even really alter the air. It will however increase humidity.
If you want to try.something a bit faster to raise humidity without spending money, hang a towel in front of a fan with the bottom sitting in the water in the tray. The towel will suck up the water and the fan will evap it off the towel very rapidly.

Yet again go on what the plants look like rather than what a gage is telling you.

I have not had any kind of gage in my room for around 7 year now,the plants look hgappy I'm happy,same had pH pen ain't used one in about same length of time.

Honest I feel that going on these gages can cause more problems than they do benefit your growing,but I have good water .I grow in a hydroponic system ,and not very often I have problems.Make sure that your plants have some kind of extra air going to your roots via,a compressor, or a simple fish tank pump.Use spegetti tubeing in the bottom of your pots with a layer of larva rock or clay balls covering the air ring then medium on top be it soil coco even rock wool the plants love it just give them a mist during veg,I only do this just in case there has been any kind of dust,but my room is air tight clinically clean,but the plants seem to like the mist .

Hope that this helps
Peace tyke

Ok thnx for all the opinions and help.

@tyke: You use one pump per pot or you run the tubing through every pot from one pump?.
