Hm. I wouldn't really listen to the manufacturer considering growing weed is illegal in China where they make them. LolI have a decent light. The aero light se100w. See the thing is I have the grow hub with VIVOSUN and the seedling stage legit started off at 60% which even I thought it was high and I don’t even know what I’m doing. So I turned it down to 45% and then it started stretching. The day after I put back on 60%, true leave started forming so that’s why it may seem like I’m starting off with high power. I was gradually increasing it by 5% every week. Being im on week 3 at 75%. Seedling is 60%, veg is 80%, and flower is 100% for their program. I never had light burn so I thought I was doing fine but I could be wrong. I’m in a 2x2x4 with not a lot of vertical height so that’s why im mainlining
Go by what the plant is telling you don't go by formulas or programs. There is a number (dli. Daily light integral.). Daily light integral (DLI) describes the number of photosynthetically active photons (individual particles of light in the 400-700 nm range) that are delivered to a specific area over a 24-hour period. (Cut and paste sorry lazy) Too much and it stresses out. There is a maximum. I grow my mom's under 100w LEDs dimmed to 20% and they grow just fine. With 20hrs of light....
See what I mean. Less light for longer = same dli as high intensity for less hours. But it's less stressful and more photons are actually absorbed by the plant and used for photosynthesis. If it's bombarded with too much light it can kind of shut down.(And wilt)
