Led distance

If you want to grow tat way y buy should an expensive light. You should have just bought a few cheap 100watts. You are defeating the whole purpose of having a good light and you aren't doing anything by highering the height and the intensity. Just leave it as it is and save yourself watts. You really don't need to veg with such a top watt light. Even at 25% you do know you are using about 50-70% of the power anyways. All electrical products have a minimum working watt just cause you dim it doesn't mean you are saving watts, (if that's your reasoning) Anyways. Leave it at 25% if you want but it really can take more. Check out your ppfd map that light comes with. You are using it all wrong pal. Well your method at worse is off. I suggest you read up about light and how a higher ppfd increases growth and photosynthesis with the addition of nutrients. Its an auto so you want to get a clear understanding of your light to get the most out of it, as now (in veg) there's no real big difference. As I said, you really are best saving money and vegging with a 100watt light. I vegged 13plants for nearly 2 weeks with a 100watt. Anyways, you want to move that light close when pre flowering starts and turn it up full blast, or else what's the point of forking out all that money. So, importance of lights and how a high ppfd with a high co2 or at best make a negative pressure environment. I've seen the results already and the growth doesn't lie. Good luck.
