Starting my first grow its going to be 3 drip buckets/bubble bucets under 250/300w of hps (lumitek with the super lumen switch) 25w of Florescent and 184w of cfl. I have been reading stickys and other post but, can anyone help me out with TDS and give me some tips and pointers? Also do drop PH kits work alright? should i use rock wool for clones or not? Anything is appreciated. It would really help me out.
