@BEACHBUDZ757, thanks for the kind words and checking out my grow man. Yeah I always start my seedlings off under the B spec light for the first three or four weeks then I switch to the HLG 350R in my 2x4 tent for more veg time. I’ll start flowering in my 2x4 and then after two to three weeks I transition them into my 4x4 under the scorpion diablo to finish them off. Honestly I’ve seen Dr Bruce Bugbee talk about lighting and he says there’s not much evidence that blue light does or doesn’t do anything extra. I mean light is light and as long as the plant is getting the proper PAR and DLI for the stage of lifecycle that plants will grow. I do find that the blue light does keep them a bit shorter and bushier with tighter internodal spacing. I wouldn’t say it’s necessary to have B spec, but I use it anyway.
