Thanks for the help, think i'll have a few more questions no doubt. I wrecked my spine a few months back and buying my medicine is costing a fortune.
actually i run the same amount of blue in each flower and veg...the reds are not as critical in veg as 630nm will work but will not perform well in flower...a deeper red of 660nm is needed for good performance in flower:jointsmile:
