So you're going 13 11? Can you tell me why....I'm new at thisUnless I'm running vertical lighting I'll partially defoliate the lower 1/3 of my plants since not much light is going to get through a dense canopy anyway. Those canopy fan leaves are like little solar panels but they will block light. What light does get through will be a result of canopy movement and at lower intensities as a result of the distance from the light.
When flowering at the tops I like to see a broad spectrum lamp (I get this with an 18" lamp-canopy separation) emitting 600-700 uMoles over my 13 hour lights on cycles. This gives me between 28-33 Moles/Day which from my experiences with Indica dominants has been ideal. If I have multiple lights and put the lamp-canopy distance @ 12-14" that same 13 hours will put me in the 40 Moles/Day region for Sativa dominants. There's a Moles/Day chart on page 17 of the link I gave you that will make this easier to understand.
On a 4 ft plant with good canopy movement I aim to get an average of 200-300 uMoles at the lower flowering sites but unlike the canopy where light is a constant intensity this is going to be an irregular reading unless you LST. If I've got multiple plants running taller than 5 ft I'll run the vertical VPAR light, no defoliation and pick up the lower branches that way.
Yeah I haven’t been able to find decent par meter either. And going by what they say about par being between 400-700 nm still does not give an actual intensity. 400-700nm are colors not strength of the light.not anything to do with penetration power. Power is the deal. If par is what they re saying. it is more related to spectrum not how strong the light is. So I’m definately confused now.so the PAR needed is 400-700 nanometers - so a 300 is rated 716 PAR at 12 inches / 312 PAR at 18 inches/ and 233 PAR at 24 inches > so I have good cover at 18 inches + Now with 2 45 watt 12by12 side panels night hadd afew PAR's _ AM I thinking on the right idea???, (for a bit it was LUmens - understand them but PAR is the realmeter) was going to buy a PAR meter and many reviews said they are junk .not getting one
and that come's to 45 par per foot??Yeah I haven’t been able to find decent par meter either.

Yeah something like that. I just try to put as much light as I can n back off if it looks like it’s burning or drying too much.and that come's to 45 par per foot??

Veg or flower? With co2 like that i would say 1000ish maybe as high as 1200ppfd veg 18/6Why does everything have to be so damn confusing? I run CO2 at 1250ppm, my temp and vpd is dialed in. From what I gather I want the par meter to read 750+ but no higher than 1000 correct or no?
That is for atmospheric co2... around 400ppm. I wouldnt say its the max but for an 18/6 I would say that fits the bill.According to coco for cannabis, 60 ppf per square foot is the maximum amount of light that the plant can use (not sure if that is with or without added co2) and max ppf is 1000, again not sure if that is with or without co2.
