I figured you weren't getting much response on your thread, so you put it out separate. I should have continued the convo on your thread.Oh fuck I see what happened I put it on my grow journal than it’s on this led thread shit I confused myself lol
So I should probably just build another light and use the sp150’s for vegI would want 400 umol/s down around the bottoms and around 700 at the top of the plant. That works out to around 15k lumens at the bottom and roughky 40k on the tops depending on levels of blue green red output and led efficacy.
People regularly throw 100k+ , cough, HPS, cough. in production all the time.
I would still want 4-500watts of actual light hitting a 4x4. So if the fixtue is 60% efficient it would need to about 660 working watts from the wall. If its less efficient, overall wattage goes up aka more fixtures needed.....
What @Oreguhnism said is spot on. It depends on your goals.So I should probably just build another light and use the sp150’s for veg
I figured he didn't get any responses here and he posted around noon. (Kinda funny how minds work) So I figured I would get the convo started. Lmao. Didn't mean to cause any confusion but glad we're getting some ideas goingI figured you weren't getting much response on your thread, so you put it out separate. I should have continued the convo on your thread.
I see where your at now. Those definitely have an advantage over QB's for coverage. You could just add more bars to the same light and change drivers. Cool set-up.This is the one I built I don’t have to worry about not having enough light on the edges because I only have 2 inches of free space all the way around the edges so the light spread is pretty even, I messaged the dude and told me to send me a set up for my 4x4 so for 350 bucks I’m going to have 500 watts at the wall 12 stripsView attachment 78815View attachment 78814View attachment 78816
Exactly. You can’t have .11 of a light so I rounded it up to 8 to be safe. LOL.One sp150 covers 1.5x1.5 =2.25 sqft.
So there are 16 sqft in a 4x4. 16/2.25=7.11
I'm was just going by the numbers Mars published.
That’s crazy I thought that light was pretty good when I bought it turns out it’s not the best it with those to get 8 that would be over 1000 bucks that’s definitely not work it lolExactly. You can’t have .11 of a light so I rounded it up to 8 to be safe. LOL.
They're taking a good idea and charging what they can get for it. Remember when flat-screen TV's first came out? Only drug dealers could afford themThat’s crazy I thought that light was pretty good when I bought it turns out it’s not the best it with those to get 8 that would be over 1000 bucks that’s definitely not work it lol
