I use GH Flora Nova nutes like DW. The Lucas formula is based around them. If you think they are deficient then talk to GH or Lucas.
The sun maxes out at 10,000 lumens but those bulbs knock out 15,000 and that's measured 1 foot from the source. At 6 inches the lumens are more than doubled and at 3 inches they are way more than quadrupled. That's 60,000 lumens directly on the leaf that you are talking about and you think it's a nute def?
Let's just say I beg to differ.
A 1000w lamp produces 150,000 lumens... I don't think a tiny little CFL producing 9,000 lumens will outshine that.
If you want a mature debate, PM me. Don't use childish comeback like " If you think they are deficient then talk to GH or Lucas." It's childish and immature to say the least.
Again, my 250w is 3" from my main cola, no issues. You are a little confused on how lumens work, this is obvious from your explainations.
Lets say you have 3 plants positioned around a 42 watt cfl. All 3 plants are exactly 2 inches (same distance) from the cfl bulb in the middle, the cfl bulb is 2800 lumens.
Question: How many lumens are each plant getting?
Answer: 2800!
The trick is to have your plant getting hit by as many cfls as possible at the same time. This does not increase the lumenous intensity your plant is getting, but it does increase the quantity of light your plant is getting from certain directions. If your plant is getting 1650 lumens from one side because it is 4 inches away from a 2050 lumen cfl, and on the other side it is right next to a 2050 lumen cfl getting a full 2050 lumens, then in theory the plant is being exposed to 3700 lumens of light at varying intensities from different angles.
Perhaps your strain was hyper sensitive to light.
Hope that makes sense. If you want to discuss this any more, just PM me. Would be more then happy to BS with a fellow growing brother. If not, then best of luck with future grows ! Nothing but love.
