General question about light
Kenni, that may be true for water holding culture, I am using SemiHydro
clay pellets that drain free water instantly and require a small sump that holds water to provide for the wicking of water up the pot internally, and in my case keeping the pot wet. In my use of clay pots, which is not true SemiHydro, I need a saucer to hold that water. The beauty of SH is that there is much air space in the culture all the way down the pot bottom as well as damp clay to allow the roots to breath and adsorb (or is it absorb) water and food. Someone will calculate the free air space one day and my guess is about 30% throughtout the pot. I may very well run into trouble with this approach but it makes sense to me. I use RO water and very low levels of sea weed solution as a food. I simply had to much trouble with bark, charcoal and inerts so have switched to expanded clay. I use clay pots rather than plastic because the wind blows my plants over in plastic. Is that enough air circulation! ;-)) Hey, I do listen to you folk, being a newbie I need the information and am very glad this forum and others are so free with help and advice. Thanks!!! Joe T |
