Anything Ive missed?

Hi.

Im new to this whole growing thing and I was wondering if you could cast an eye over my plans for a hydro setup.

I have a 1.2 x 1.2 x 2.0 secret jardin grow tent, a 600w light, extractor fan, carbon filter already.

But due to money issues im wanting to make my own drip feeder system, like a dutch dripper, they cost around £200 over here in the Uk and I can make it for around £60

So heres what im planning

Could You take a look and say if im missing anything important.

Also what kind of nutrientswould be best for a setup like this?

Many thanks :rasta:
