How many watts per square foot with Autoflower....

What's up my LED brothers......
Wondering how many watts per square foot for Autoflower plants?

Also 35watts per square foot???


Much love

Depends on the LED, if it's a quality one you can run 35 watts per sq ft, if it's not quality then more closer to 50.

Yeah running 4 luminus cxm22's 3500k 90 CRI per 8gallon pot.....one cob per square foot you know...

Yeah you should do very well with that setup.

Just so used to seeing people with a cheapo chinese blurples asking such questions... lol

Around 25w/square foot to compensate for longer light cycle.

Yeah you think that's enough brother?

Id spec my light for 35/foot and dim it later. 25w for 18 hours is the same amount of photons as 37.5 for 12 hours. But give your plant all itncan take by all means

And brother you are talking autoflowers right?
Man there is people saying 24 hours light made all the difference others say they only do 18 hours....still think I would go with 20/4 full cycle.

Yeah. With 35w per square foot you can flower any cycle. 20-25 for autos depending on how long your cycle is usually enough, in the end your plants will tell you.

Right I know about the 35 watts for regular cycle. Wasn't sure since there is people out there saying their Autos do better with tons of light and that for 24 hours straight....you know........I think with my four cobs I'm just going to go with 25watts per square foot 20/4 and see how it goes.

Much love brother

Go for 35w per sq foot and youll yave enough for any scenario. Give your autos as much light as they will take, but remember its easy to go over board with led.

So brother would you rather run the 25 watt cob per square foot for 18/6 or 20/4, for autoflower plants I mean.

I would run boards or strips at around 25w, making sure you can turn up to 35 if you ever did a normal photo-grow

Alright man appreciate your answers! Much love

Never understood those "watts per square feet" things.

Go with PPFD and DLI. It is more accurate.
