According to science the sun puts out around 8,000 lumens of power. However the brightness of the light allows the 8,000 lumens to penetrate into even the smallest crevaces on the plant. Natural sunlight isnt as bright in the PAR spectrum as an HPS. But it has extreme velocity if you will. Indoors with a light you need reflective material to focus all of your light into one area. As to where outdoors the light is soo prevelent none of this is needed. If youw ant to equal the light of the sun buy a 150 watt CFL. Want to blow it away 600-1000 wattHPS. I hope this hjelps!

No offense bro, but thats kind of laughable. a 1000 watter loses its strength 4 fold for every foot away from plant matter it is. So the further away you get horizontally and vertically from the light. The less lumens they recieve. The suns light travels 93 million miles, so i don't think an extra five feet that the plant is tall makes much a difference. But growing indoor you can cut off the leaves that are 3 feet below the canopy cause they are going to draw more energy from the plant than they will recieve in artificial light energy.

Please excuse me but I have to correct a myth: the plant uses it's leaves to *gather* - not piss away - energy and convert it into carbohydrates. Let me repeat it another way: you are cutting your production of bud and the overall health of the plant when you cut off leaves. The more leaves you have, the more bud the plant creates. Ask any master gardener and they will tell you that. On topic: I use the sun for my grow but I bring my autoflowers inside and put them under lights so they get 24/7 light. I also have some full season plants that are small enough to bring in and I put them under the lights as well.

it depends how big the fan leaf is and how much light hits it

Nothing even close in exisitance. I guess the flash from a nuclear explosion would be close. But regulating 12/12 is a bitch! And the heat issues, dont even wanna go there. Edit: Should have said, 'no bulb even close'

No excuse necessary, in fact i'm glad you brought it up because I've heard contradicting opinions. They range from your lights won't reach leaves/branches 3 feet below a thick canopy. Also, heard your opinion. Also if a leaf is 50% dead, its lack of chlorophyll isn't enough to justify keeping it on the plant. My theory is. If my plants were out in the wild. The wind and rain would knock these dead p.o.s. leaves off anyway so its not like its un-natural. If you are correct, that lower branches gather enough light to carry their own weight. Why do people scrog and clip their branches 2 weeks into flower? I don't think anyone disagrees that leaves produce energy, but at what cost when growing indoor with 5 foot plants, Rosenthal's opinion in the book "ask ed" is that light will not penetrate through more than 3 feet of canopy. Perhaps you can help clear this up for me potpimp, this is one of things I've been going back and forth on.

I bought a 50 dollar light meter. Its really a great tool when it comes to effectively lighting your garden. And in my opinion if you are growing 5+ foot plants indoors. By trimming the lower third or so. The plants are actually happier from the additional airflow gained throughout the garden.

Thanks Skunk. Check my journal. Its going to be covering some of these very questions. My sig is a link.
you can get rid of fan leaves about 4or 5 weeks int flower not before even thne only remove the fans from stem not fans sticking out of budsat this stage des no good to buds as a matter of fact removed ther is more energy to the buds and fans were used for growth which is not the focus now in case we dont know focus is now put to budding flowering the 12/12 the good time of grow the best time icant wait time are we there yet ?

Let it be said. I don't just go around chopping my leaves off.
So what ur saying wait 4-5 weeks if you're going to remove fan leaves. I don't make it a point to take out unnecessary leaves, just the dry crispy ones. What about removing the lower branches? Like was said, my plants reach 6 feet indoors. I was told that you should remove the branches that are going to yield you about two bowls worth and do this either 2 weeks before going into flower or two weeks after going into flower. Those are the times when a plant can deal with the stress and rebound without any issues. That lets the plant focus that energy on your main branches. The ones that are actually getting light.
Think about this. You trim the hedges in your front yard and the shit comes back bigger, thicker, taller. Why? Could be thats just life. Or does the plant rebound quickly because it has the same amount of atp to put into less growth? Any input helps. Im a newb on here but not in the garden, and this is one area my partner and i argue on anytime I pull a crispy leaf or want to trim a scrawny branch.

If you are going to trim. Trim during veg. Once into flower keep them as green and healthy as possible.

The sun produces about 8,000-10,000 lumens per sq. foot on a warm sunny day and it also depends on the latititude and positioning of the sun.

If a leaf is yellow and I don't think it has a chance of coming back, and I've had that to happen by hitting them with nitrogen, it's best to remove it, absolutely. I don't think that the leaves "take" anything from the plant, but it probably doesn't add anything when it's yellow. If it's yellow, there isn't any chlorophyll and that's the little chemical engine. The energy of a light does not drop on a linear scale from the distance to the plant; it drops to the *square*, exponentially. At 8' away, you're just getting a little "light", not any real energy. If you have not checked out a grower on here named Uncle Ben, please do so; he's a master gardener and he knows his stuff!!
