IWG sells what are commonly known as "Luwassa" pots. They have a net culture pot to contain the medium and plant, an outer pot to act as the reservoir, and a gauge to determine the depth of nutrient solution in the reservoir. I have several tropical houseplants growing in them, and they're really nice. I don't know what brand of medium she sells, so cannot comment on that.
The pots are FAR better looking than the translucent containers I carry, and being opaque, don't grow algae nearly as well.
However:
- It is possible to overfill the outer pot and drown your plants.
- They are not self-flushing, so on a periodic basis, it will be necessary to remove the inner- from the outer pot and flush the medium thoroughly.
- You will need to dump the reservoir before each watering. Plants don't absorb nutrients evenly, so between that and the effects of through-the-root respiration, you won't know what the solution chemistry is if you merely top it up when you water.
- They are significantly more expensive.
