Its not aeroponics , this plants are called air plants , which
mean they don’t need soil to grow . You have to spray water onto
the leaves which will then be absorb by the leaves and grows . You
can afix them to wooden log or stone to make it more pleasing to
the eye . But from what i observed , most pple fix them to small
wooden logs or aquarium logs to help for easier or better growth
and as time passes you may even see them forming roots clinging to
the wooden logs to absorb moisture . I tried buying 5 of them but
alas all of them died , last one died after 3 months as i still
can’t figure out how to grow them well . But if are able to grow
them and even let them burst into full bloom , you will be very
excited to see their flowers which is indeed very colorful and
luminous to certain extent .
