I watched it and it's a great video if you live in the UK,
the nutrients shown aren't the same ones we use here in the USA, it's does have a great time lapse type movie of the growth process .
I made a dvd of it to send to my brother back east.
but I'm gonna tell him to ignore all the tips given in the show on the feeding of the plants and give him my feeding schedule instead.
I don't like the fact that he mixed the nutes with each other instead of mixing into the water.
his plants sure grew fast though!
