Well Mike, hopefully our cheerleader will give you the extra push lol...
My roots are sprouting more and more, as I am learning how to control the mist. I dialed it back to .3 sec/5 minutes, and the roots began to yellow and dry up, so obviously it was not enough for now. Perhaps once they grow out a bit and are able to take in more water efficiently those timings would work. To be honest, I don't even know if the solenoid has enough time to fully open before closing again in such small spurts- although I believe it's spec's said 200ms. I have the timings currently at .4sec/3mins, and it seems to be a good compromise for the time being. tree farmer recently told me that he would like to see some good roots with fishboning established before trying to dial down the timings. I also remember Atomizer saying even at 1/4" root length you could push them to fuzz, but I believe especially since my temps are so high that I should not stress the plant and roots by starving them of water just yet. The whole time the new leaves which spung forth after the original ones that dropped post-transplant, have stayed healthy and green. They are a little lighter green than before, but I am sure the plant isn't getting as much nitrogen as it would like until the roots can absorb more. I could foliar feed, but I don't think it will be necessary, as the roots are still growing and like I said there's no real emergency in the plant's condition. My biggest issue is this is taking longer than I bet it would if I knew what I was doing. I like the learning process though... All I can say is I will never go back to recirculating, it is so nice to make up a batch of nutes, and know they don't need daily testing and tweaking. To be honest, I have one other clone still potted, and it requires more work to water every couple days than the cutting in the chamber which only needs a res refill every week or so!
I've been thinking of ways to keep the chamber cooler and I think I have an idea. I am considering adding a small computer fan that will push air in from the outside under the silkscreen and through it into the bottom of the chamber.. The air will push through it like a swamp cooler, and cool the air through evaporation. All the hottest air will push up and out the top through the netpots, and it might even help them get fresh oxygen. I don't think I will need too much flow, but just enough to slowly push out the hottest air that builds up in the chamber. I am not sure if this air flow, small as it will be, would somehow be too drying to the chamber, but suspect it will be easier on the roots than the heat is... I may be able to get away with just drilling a few holes to the outside down there under the silkscreen, convection might be enough to cause the hot air to rise up and out, while drawing in fresh air through the bottom and silkscreen. This would be even more ideal, because it does not use any electricity, and will only draw in air if the chamber becomes warm enough to start the process...
