I have 2 DS200 advanced LEDs that have a flower and veg. mode ,each run about 185watts each.I have one G8 140 watt,this one does not have a veg.switch I run all on full power after about 2 weeks old.The plants seem to love this set up.I keep them approx.12 to 14 inches away from canopy.When they start to flower they will take all the light you can throw at them.I just bought 2 BMLs LEDs,these are 75 watts each,i,m using these for my seedling table.After my seedlings get about 2 weeks old,i put them under the other LEDs i have and use the BMLs for supplemental side lights.These are 36ins. long and are good to get penetration on the lower branches.I got a little long winded there bro,i hope that helps.Peace.
