0.5 inch++ of charcoal on top of gravel,then cover up by peat moss subtrate. Is it good or needed? If so, how does it help? Does it help increase humidity by maybe absorbing the water or help evaporate it from the gravel layer? Charcoal absorbs moisture so would it somehow work the same for water? The got the idea from the evaporative cooling system thing. Its method is of moist or wet charcoal with the help of circulating warm air to aid evaporation thus increase humidity and lowers temperature if im not wrong about that. But will it still work under a layer of peat moss subtrate, minimum air circulation, maximum only by the help with a pipe tunnel or straw heading straight down to the charcoal layer from the surface. Any thoughts guys? I googled that evaporative cooling thing btw.
This is what it looks like
Im making a experiment. The box on the left is charcoal on top of gravel. Middle is only charcoal bellow the sphagnum moss, and the one on the right is gravel under sphagnum moss. 3have almost the same thickness of wet sphagnum moss on top and the same water level at the bottom, left it at the balcony. Its always summer here btw, so i think the results will be fast enough. The one fastes to dry out will be the most efficient. Its only a small experiment based on rough estimation, not sure if it would be accurate tho. Wish me luck
Theres already alot of moisture going on in the boxes
Will keep you guys updated. Wink*
