does what it says, it's much more concentrated phosphoric acid than others I've tried

of very good quality but they are very expensive, in a future I would like to try voodoo juice that seems interesting. b52 is my favorite

Diamond nectar is a must

good value for money but the packaging is bad and poor documentation (some products you do not know what's inside)

For me they have a great value for money! recommended!

work as expected, no light leaks, openings where needed

To be the entry level model I must say that it is excellent and that I recommend it. The only flaw in my opinion is that it has a bit too cold light (but it could also be an advantage if you use it for the vegetative phase only)
