Hello,
I have a SF2000 and a SF1000 in a 2x4x5 tent. I see all kinds of discussions about how high they should be above the tops, but not much on where the dimmer percentage should be. I have them 36 inches above with 60% dimmer for veg. Any help here would be great.
Thanks!
Hello, thank you again.
Here is the chart from spider farmer
I also have a sf1000 as well, so right now during start of flowering I have the knob at 90% at 36 inches as I am not sure what the par is combined for both units. Would it just be the 974 in the middle at 18 inches plus another 500 ish for the sf1000? I do want to maximize plants but not burn them. So with your math of 600 to 900, should i lower to 24 inches?
