yup. they are all in miracle grow (various kinds, depending what i had at the time, so far ive used regular, organic, cactus and citrus, and orchid). no regular fertz. every month or two i squirt some miracle grow liquid fertilizer into the water between the pots when i top off.
Have you noticed any different growth from different soils?
cant say. i didnt keep track of which one i used for which plant. plus for most plants i only have 1 pot, so no control group.
but i think the difference in terms on nutrients is negligible since the soil is water logged and been sitting the same pool of water leaching nutrients for months.
the only really difference i suspect would be particle size. the orchid mix has large particles for drainage, and fine root plants might not like it as much, but the HC in it still grows very nice (this one i know has the orchid mix, since its so noticeable).
the tubs are starting to run down slightly... they need new soil. theyll get it next month when im done with school.
but most of the species are still doing spectacular. the c. wendtii and a. frazeri are flowering again - the a. frazeri actually still has the old flower doing well and is sending up a second. and c. parkeri (one of the pots) is flowering too.
