Automatic Digital pH Controller

[al3k5]

Dont know if i will buy the six plant starter kit, but will probably instead make one similiar to it. What i was interested in on their site was the Automatic Digital pH Controller which claims to automatically adjust ph? Do i not need ph up / down solution at all? How does this work? and does it work? anyone use it before?

Thanks,
Aleks
