Not completely true, while the soil particles will prevent outright splashing, the cavitatingbules will begin to percolate upwards and carry water with it. i watched some Youtube on some bubble bucket kind of setup with a transparent pot. When the air was turned on the reservoir water did...
i am going to engineer several mixes and actually measure the Overall airspace, water holding capacity and water wicking height. I will also do this for several container heights including 16, 24, 32 oz solo cups, 2 liter bottles and 5 gallon buckets because overall airspace percentage will go...
I just lost a post i worked on for an hour so i will be briefer in this post. Yes Wattsaver, Your current post explanation is correct, the peat layers is acting as a sponge which holds an upper reservoir of water that slowly drains into the perlite. The Scientific explanation is one of soil...
You are correct, capping the perlite with coco or any finer medium will only act as a mulch layer, but it can not help wick the reservoir water higher in the perlite. While some media may have more sponge like properties such as vermiculite, the basic physics of water wicking is particle size...
It is likely thatone could supersaturate the water with DO. Is that a bad thing PROBABLY NOT! I think i have seen charts that have max ao2 levels n fresh and sea water topping off at about 17% usually tapering off at the magical 68 degrees but more often fresh water lakes are 8 to 12 ppm DO...
