To be honest im quite young to growing so, I started small and simple and ramping up to more complicated things. First grow was 32oz comp on AFN, with a safe bet of soil,coco and bit of perlite mix. came second in the comp!
Bit like playing golf really, you can try and hit a tiger woods on each shot and end up deep in the shit, or just be realistic with it and do something sensible.
I really wanted to do it that way cos there will always be lessons learned, just cant go from nothing to superhero, without making a cock up somewhere, likely a few.
Second grow Im testing airpots and something bit bigger, will start up a thread for it soon, spending some efforts to create a timelapse vid for this one.
The DWC will take some time to get together, so no rush but I recognised its going to be a matter of good process control so I will give that a crack once Im ready. In the meantime I will do a few much simpler grows and build up some experience
Yeah that's the danger with water cooling, got to be careful and make sure you do it right if doing it at all, the worst case is a big spill. And if your using another liquid than water which can be the case, then prbly not a good idea to smoke that after!!!
safer bet might be to figure how to channel the output air from the sides of the led unit and route it straight out of the box rather than recirculate inside I guesse.
Im no fan of overcomplicating things when they don't need... or just reinventing a new wheel just for a laugh, but then I have lots of my own ideas and a love for trying things. Got to hit some sensible balance between output per £ spent tho. £5K sounds bit much for growing a few weeds to me. you can buy a lot of good shit with that!!!
raising CO2 concentration should not cause O2 concentration to drop really. Like you can have a lot of salt and a lot of pepper to. Early earth had a higher concentration of both co2 and o2, when things grew like monsters.
CO2 the plants will love during the day, O2 is absorbed as the other half of the breathing of the plant, mostly at night. some is used at the leaves themselves (you should have a good enough concentration of it anyway since the plants been making O2 all day long, unless its all been flushed away back to ambient O2 concentrations by the venting, still fine for most. O2 is also used a lot by the roots at night particularly, so keeping the dissolved oxygen concentration of the DWC water good is the aim.
O2 concentration which you can dissolve in water is quite low, so bubbling it is what helps. But there is a limit, you can saturate the water then no point bubbling any more really, its saturated, for the ambient temp and atmospheric pressure we have, for the moment.
Lower temperature water will, by the physics of it, be able to hold more dissolved oxygen, nearly twice as much if the water temp is dropped by 10deg c rather than matching the tent's ambient.
I will come to play with this stuff one day, but step by step
Also I have plans for O2 sensors to measure the concentration and Co2 concentrations in water and air. Going by that should be able to "see" how quickly the plants are using CO2, O2 , indirectly measuring the Photosynth rate !sounds like a monster tattoo man! now the challenge to leave them scabs well alone, good luck buddy.
