i used normal compost ( the kind you get cheaply at garden centres) Usigna nutrient called Ionic which I think is a basic nutrient aswell. Like I say not very well up on techniques but thanks for the advice. I will give them one more good feed with nutrients and then water only. Thanks for youe help

Got these plants under 2 x 600w HPs woudl you say this was enough light or do I need to move up to 1000hps x 2. Also got a hefty extractor in the room should this be left on all the time or does it need to be on in short bursts.

Sorry for all the questions jsut wanted to get a decent liitle system even beter.
