true, perlite is close to inert, its a gas it does provide oxygen mostly. it has tiny nutrient value.
By God I second that statement. All this pH hooey with soil is just that - hooey.
Perlite has zero nutrient value. It is over 73% silicon dioxide and has an extremely stable structure. Hence it maintaining its shape despite watering, soil compaction etc. It's main value is making aeration of soil easier and retention of some water/nutrients due to its porosity.
use as recommended on the bag. i think its like a cup per cubic foot.
its not a a gas, perlite is a generic term for naturally occurring siliceous rock. This rock is fired in a kiln at 1600-F it expands to what you and I know as perlite. It's inert. 7.0phits a volcanic gas/rock with some nutrient value. mircale grow throws any kind of random shale in their scotts permium..its not bad soil, just not enough peat.
cant wait to try my new suff
Once again you are wrong. You just keep posting stuff as fact because "it makes sense to you.
I've never watered my plants with a h2o2 mix, though I've read it could kill beneficial bacteria within your soil. If getting oxygen to your roots is a concern, just make sure to add enough perlite/pumice to your pot, before planting.. and maybe a well aerated tea.
