Your PPFD is too low, unless you are planning NOT to run CO2. For me CO2 is about the cheapest way to increase yield in a grow.
Your PPFD is too low, unless you are planning NOT to run CO2. For me CO2 is about the cheapest way to increase yield in a grow.i was wondering what's more important to most growers here? price? quality? and what price range does everyone think is acceptable for a quality light, something that can be compared to the big boys. Let's say if a light was able to hit these numbers at 20" from canopy in a 4*4 tent. how much are you willing to pay?
even with co2 i would not push it more than 1200 ppfdYour PPFD is too low, unless you are planning NOT to run CO2. For me CO2 is about the cheapest way to increase yield in a grow.
I am sorry that does not work for me. I am looking for PPDF in the 1600 to 1800 range. I have experience with these levels and I am more than happy with quality and yield at these numbers.even with co2 i would not push it more than 1200 ppfd

e not the sameTBH I have no used that light. I run Gavita and Fluence. Your Nutrient demands will change at the PPFD increases. Also they will require Additional Cal Mag. In Coco I have to run about 7 ML per gallon for the first 3 weeks and drop down to 5ML until the 5 week of flower. Also the chart you posted is a PPFD chart. The light is advertised as 1842. This is suppose to be the average across the whole foot print. Meaning if it is shown to flower a 4' x 4' area the average would be 1842. The highest on the chart is 1394. I am afraid there is some false advertising in the paperwork.
From what I understand they are not the same measurements. One is a measurement of the total output from the light fixture,and the other is the amount of light or photons biting the plants surface.TBH I have no used that light. I run Gavita and Fluence.

But I could be wrong?

Look like good quality aluminum heat sinks to me?that's good to know...but ya...the heat sinks on it is really bad.... i had my 800 hanged i think 20" to get 1000 ppfd in the mid
Yes PPF and PPFD are two different measurements. A PPFD in the 1600 to 1700 range is good. PPF measures the total amount of light the fixture is putting off, as in all directions.Hitting the plants!
Big thumbs!
: D
i had one that looks like that but was bad...maybe urs is better...lol...just my luck i guessLook like good quality aluminum heat sinks to me?
when i pump my tent to 100% i definitely need to feed almost 1.75x normal. I end up riding a fine line between too little and nute burn. But the growth is great. I end up with weird fluctuations on the bottom, mixed with great new growth. So its a trade off. But i cycle my lights up and down throughout the day. taking me a little bit to balance out yet.That brings me to my question,is anyone using the higher powered LEDs having to up their nutes to keep up?
as a crude comparison, think of a car engine. if you increase the intake (light) then the exhaust needs to be increased (nutrients) the amounts will vary depending on your setup and the strain. but if you get the right balance you will get great returns in product.That brings me to my question,is anyone using the higher powered LEDs having to up their nutes to keep up?
You will hear comments on both sides of the fence. For a home grower in like a 4' x 4' tent they are going to be hard to bet. The challenge with HPS is the head they put off. LED's run much cooler. This alone will help a new grower suceed.im so freakin new is LED better than regular grow lights
My husband has cancer trying to grow something for him..
it depends on your expectations, how much money you want to spend, and the size of your tent or grow space. Addittionally, I say a prayer for your hubby! Godspeed.im so freakin new is LED better than regular grow lights
