Mep. These are not good enough lights mate. If you've to hold a light tat close to a plant & it only covers a small area. You need minium a 100w light or a light that puts out at max setting 800-1000ppfd Yes, u can use lights once they go beyond or near 700ppfd. Other than that your plant will stretch. Larfy bud & pretty much a big waste of time You can even get p600 or Mars TS600 100 watt. Spider-Farmer SF-1000 is a great starter light. I'm still using mine 2yrs on for vegging and starting my plants.. My point you can even pic up a cheap full spectrum phzion (not sure thats their name) but you'll see their led boards on amazon for 50$. Good luck
