Upgrading to HPS, need some help

If you look at Tropicana Todd you'll see he adds these bulbs to low watt leds with great results. Add a blue spectrum HPS bulp for veg and then a red one for flowering I'm sure a full spectrum bulb would also work. But if you gna go to these (they really are going backwards but adding them to leds ive seen amazing results. You can get a 150w grow. HPS/MH (blue spec light) this will help veg giving tighter internodes and which in turn will give more stigmata (pistils bunched up) giving denser buds. Check out his profile.. u don't need a 600watt light. Its all about getting the right spectrum pal & DLI.. a plant in normal environment can only take in so many photons. So if u getting a 600w light for bigger buds. Go with spectrum/DLI. This gives big buds/bigger yields. Is by finding a good balance for your plants Good luck
