Looks great in the large plants, smaller plants look a little dwarfed next to them as they dominate the pots.
It is clear these will only function correctly if the soil is pretty damp to start with.
I noticed there are serveral imperfections/white blemishes in the glass, but this doesn't detract from the overall appearance.
The only thing I'm unsure about is whether these would over water the plants in the winter time when they require much less water.
I just wished they sold the smaller aqua globes for the same reasonable price on Amazon.
Edited below after using these for a few weeks: -
The bulbs I received are clearly the production defective ones. I have 6 of these bulbs with 2 of them with small necks which makes impossible to refill under the tap. Very frustrating.
Some of these are good quality with wide necks, these are fine. I don't mind blemishes in the glass, but these small necked bulbs are not usable.
Changed rating from inital 5 star, to 3 star.
