I'm not familiar with that led fixture. Do you have a link?
Thank you!Well co2 will make a difference in all of it. Since you brought it up I'll go with co2. And assuming you meant the ion 720w fixture?
Light intensity should be measured imo instead of just height.
I run leaf tenp of 77-80f depending on the strain. This can range from 80-84f room temps.
Co2 ppm I start early veg with 600 working up to 1200 by mid to late veg and then back down to 600 after bud swelling is complete.
I run VPD minus 5-10% because of costs reduction to transpiration rates.
Ppm depends a lot on media and additives used. Typically hydro 600pm is about as high as I need and soiless 800ppm. Sometimes a touch higher depending on how hungry the strain is. If you run humidity at VPD levels you may find you need to up the ppm.
Under LED your going to have quite a bit more blue in the spectrum which is going to keep plants a little more squat than your used to. You all probably see a difference in bud structure but you should easily equal or surpass your yields with a HPS if you transition well.
The temps are the biggest hurdle to get used to so I suggest a cheap IR temp gun to take all the guess work out.
I'll leave it there. If ya have any more questions I'll do my best to answer.
Hey Aqua Man. What about the supplemental UV bulbs? When should I run them? I heard a couple of hours a day. Some say last 3 weeks. Thanks in advance!Well co2 will make a difference in all of it. Since you brought it up I'll go with co2. And assuming you meant the ion 720w fixture?

Thank you!I use uvb for the last 4 weeks. I've been playing with timing. I've done both 5 hours a day in the middle of the 12. And I've cycled hour on hour off for 10 hours in the middle of the 12.
I think the cycled uvb was better but havent had any tests done.
You should do well under that light if their par numbers are correct.
So this thread is a gold mine for UV its still a science in the works imo.Hey Aqua Man. What about the supplemental UV bulbs? When should I run them? I heard a couple of hours a day. Some say last 3 weeks. Thanks in advance!

Should I add UVB Light?
Hello, I have been growing on a very small scale for about 4 years. I am always trying to learn more about growing and I know that I have so much more to learn. I also know that it's probably a life long process! I started with auto-flowers in a 2 x 2 tent with a horrible LED light. I also...www.thcfarmer.com
Np... hope you may decide to do a journal for us all. I'm sure there would be many interested in following along.Thank you!
I will. Thanks again for all your help!Np... hope you may decide to do a journal for us all. I'm sure there would be many interested in following along.
I replaced 8 4’ T5 bulbs with that light. Way better for half the power.Can I use this LED light in replacement of my T5’s for veg?
May I ask what your connection to the company is please?Hey, are you still wondering about choosing your led grow light? If you are interested, you can take a look at this product: https://www.hishine.cc/PG03-LED-Grow-light/led-grow-light-800w.html .It might help you
Your plants will eat more under leds, get ready to feed more.....also you must bump the Mg ppm to at least 80, were most nutrients mix have it around 40....get some epsom salts.What do you run for nutrient ppm’s
What nutrient ppm’s are u running at? How much epsom salt do you add? Thank you in advance!Your plants will eat more under leds, get ready to feed more.....also you must bump the Mg ppm to at least 80, were most nutrients mix have it around 40....get some epsom salts.
Also N and Ca needs a bump under bright led fixtures and co2!
