I upgraded my flowering light last month to a 400 watt HPS from a 150 watt HPS and its the best investment Ive made. Took me a couple weeks to get some things running right, but got everything straightened out. Main problem was my intake was stronger than my exhaust, now all is good.
I see the difference immediately from my upgrade, my flowers grow faster and way more dense now. The Hasplant is the first to be flowered only under the 400 watt light. Those little flowers are rock hard already.
Here's Hashplant x Haze at 18 days flowering:
Skunk #1 at 4 weeks, got burned a little before I got light and exhaust issues straight:
The result of my first attempt at breeding, and Im pretty happy. Good yield and mouthwatering taste. Tastes like Blueberry and Oranges. Its Mom was a bagseed that I grew out and had clones of, Dad is DNA Genetics Kushberry x Skunk. She also got sme light burn but was healthy enough to grow out and harvest.:
