GREEN24 Epiphytes Tillandsia Bromelia (Aerophytes or Air Plants) Liquid Fertilizer HighTech NPK, Epiphyte Foliar Fertiliser - Plant Food

This seems to work (well, the plants haven't died!) I found it hard to source ready-mixed 'air plant' spray so ended up getting this (I believe it works for other types of specialist plant also, possibly orchids so has a number of uses). The instructions are mainly in German but aren't too hard to work out as they're mostly numbers giving proportions of water to feed. I need such a miniscule amount each time that I worried I'd over-feed and burn the plants, but they've been fine and have flowered a couple of times. As this is highly concentrated this small bottle will last me just about for ever so was excellent value!

This product seems rather expensive at first glance but as it’s concentrated it works out to be a really cheap alternative to the air plant ready to use sprays. I’ve got a small spray bottle to dilute the liquid and it should last for a long time, giving my cute Tillandsia lots of lovely nutrients.Hope you found my review helpful

Seems to work plants are growing.

... and the plants are still alive so I guess it works! If they grow to monster size I’ll update this review! 😂

Seems to be working well on my air plants well. Small bottle but will last for years.

My air plant love it and are growing faster than usual.

Nothing negative at all. Plants doing well so must work fine.

Good
