Hello all
I found some Red Lava Rock at Lowe's intended for landscaping- or thats what it says on the bag! It weighed a ton, could barely lift it haha.
Can I use this type of lava rock for orchids, i might add some of this rock to my orchid mixes and maybe try some in SH-
I looked at that stuff before but I bought a smooth rock instead. I used it at the bottom of the pot to give it some weight so they don't blow over since they are outside. I have on orchid growing in marble so I guess you could use lava rock. I don't think you can use it for S/H since it probably doesn't have any wicking abilities.
Anybody have a minute to explain what wick means?? I'm not familiar with that term.
Brenda - wicking it the ability of the medium to draw the moisture upwards - like if you dipped the corner of a paper towel into a puddle of water - the paper towel - 'wicks-up' the water - absorbing water into parts of the towel that are not dipped into the water
