Careful, you CAN give plants too much light

Scientific studies at various universities on cannabis have shown the greatest yield and potency occurs at about 1500µmol (the sweet spot) but cannabis also continues to increase yield and quality all the way up to 2000µmol and higher but after 1500µmol you experience diminishing returns.

Did you dredge up this old thread just to tell them they are wrong, and your light stressed plants are doing just fine?

Yeah fact matter. Look at your plants, then look at a healthy un stressed plant

Right.. because they are barely if at all light stressed and receiving much more light and producing much more than your 400umol grow and besides my plants are not what was used to measure the FACTS of this matter. You are not smarter and don't have access to the equipment that professional scientists used when measuring these results. Nor do your plants or your eyes refute countless universities and scientists.

And you do have access? At the bare minumim, you do know your plants need an increase in everything else with this much light. I hope you have co2 and you really need to increase your feed ppm. Ive never heard of anyone casually growing under 1500 umol in a 4x4

Obviously you need to increase co2 and no you don't just pump up nutes you give your plant what it needs by reading the plant..

No I don't have access to the equipment the universities and scientists have but I listen to them. What are you doing?

Ive grown under real high watt led before (1000 watters) and i cant really believe your plants have not died yet. Probably because of the co2. But they really do seem hungry.

Your feed schedule is not going to look like anyone elses. These things are going to be real hungry under all that light and growth is all in sayin.

Im trying to mind my electric bill before i go back to the two 1000watters so im only using 400w in a 4x4 so we are very different right now. I do drain to waste hydro.

Good luck man, i never meant to throw shade it just raised my eyebrows when i saw all that wattage.

No I don't think you can based on that picture and again the discussion was about the science not you being unable to read my plants.

That plant had a 3.9 ph for 2 days it has nothing to do with light which is what this discussion is about but by all means keep deflecting and proving you're not interested in honest discussion.

A plant fed with wrong ph for 2 days is not going to do that hahaha
