If your starting seedlings or clones you need "daylight/cool" bulbs thru veg cycle. Read the print on the base of bulbs & look for 5000k-6500k. The ones in your "ad" are good when your ready to flower...soft white/warm bulbs rate 3000-2700k. k=kelvin. Just check the base of the bulbs your buying, goodluck.
