Hi firstly if i have posted in the wrong section i apologize.I have been reading so many different growing books full of tips and ideas.I am now looking to grow my own but have found that i have read so many different techniques i dont no where to start.I am planning to use a bubbler which i understand how it works but i am now looking for good advice.I have bought 3 different kinds of lighting all brand new from here and there and do not no what is the best as i only want to grow 2 plants to begin with and take it from there.
The lights i have bought are a 600hps one of the new led panels blue and red not sure of power and i also bought one of the 125w ENVIROLITE/ENVIROLIGHT 6400K(BLUE/VEG) GROW LIGHT.
Can anyone recommend the best one as i would think the 600hps but with only doing 2 plants i could be wasting uneeded light and electricity.

Also i understand about the ph and cf etc and have purchased some basic nutrients a and b but not sure if i need any other nutes etc so if one of you proffesionals out there can help me with what light and all the nutrients i will need or guide to me to good site to buy these items it would be very much appreciated.Cheers
