They could send me one to try and give a review on. I build all my lights so it would be a good comparison test for me.Im.testing a sf 4000 now. Prob be ok for a 4x4 but definitely not gonna fly in a 5x5. I imagine the 3000 I'd prob good for a 3x3
They don't need em tested they need em sold lol. It's really a one hand washes the other situation but I'm not gonna sugar coat.They could send me one to try and give a review on. I build all my lights so it would be a good comparison test for me.
Send the rep my direction. lol
God, I don't need to buy more lights. lolThey don't need em tested they need em sold lol. It's really a one hand washes the other situation but I'm not gonna sugar coat.
i saw 2 meter to 2 meter table am i wrong? thats 6.5’x6.5’ thats a hell of a lot of space for a 3000 to cover.Im.testing a sf 4000 now. Prob be ok for a 4x4 but definitely not gonna fly in a 5x5. I imagine the 3000 I'd prob good for a 3x3
Yeah there high as fuck with those numbersi saw 2 meter to 2 meter table am i wrong? thats 6.5’x6.5’ thats a hell of a lot of space for a 3000 to cover.
maybe 4 of those 3000s would work well there if its indeed a 7x7ish area?Yeah there high as fuck with those numbers
Looks like it's a 320 watt setup. Good for a 2x2 maybe a 3x3 that's itmaybe 4 of those 3000s would work well there if its indeed a 7x7ish area?
SF3000??? Did you mean SE3000? The SF line are quantum boards. The SF4000 is good for a 4x4 or a 5'x5', SF2000 good for 4x2. SE3000 probably underpowered for a 4x4.Waiting on a new light to come ffrom spiderfarmer sf3000 ...
As a rookie grower I've been able to get about a pound from a SF4000 in a 5x5... I know I could do better.Im.testing a sf 4000 now. Prob be ok for a 4x4 but definitely not gonna fly in a 5x5. I imagine the 3000 I'd prob good for a 3x3
Doubt it, in a 4x4 those two 240 drivers are rated at 240 watts max, that equates to about 30 watts a square foot. Even with the best diodes on the Market that's pretty low, in a 5x5 it's around 20 watts a square foot. I personally wouldn't waste the space. I'm sure people are doing it. I've seen people grow in a 4x4 with a hand full of cfls plugged in to sockets. I personally think the stats are misleading to say the sf4000 can replace a 1000w bulb.SF3000??? Did you mean SE3000?

I have my lights plugged into smart sockets with current monitoring, I also have a Sense whole house current monitor. At an average of 123v, the 2 SF4000's in my 8x4 are drawing 1080 - 1100 watts.Doubt it, in a 4x4 those two 240 drivers are rated at 240 watts max, that equates to about 30 watts a square foot.

Grams per watt is irrelevant when u can veg for a year under cfls and grow to the ceiling. I would say grams per kilowatt hour would be a more fair comparison accross the board. Not sure who came up with this grams per watt shit but it's nonsense. You said the 3000 originally would be ok for a 4x4 or 5x5. I have the 4000 and think its pretty capable. Barely but it does work. No way is 640 watts total gonna fly in a 4x8 even with today's LED. That technology is still a ways out. At some point I think the ppfd is gonna hit a wall as far as efficiency goes .I have my lights plugged into smart sockets with current monitoring, I also have a Sense whole house current monitor.

That "1000w HPS" comparison has to do with PAR not necessarily a direct watt equivalent.
On a related note, without supplemental CO2, isn't "a gram per watt" typically regarded as a gold standard target for light/grow efficiency? Getting about a pound harvest from a 450-500W LED light seems pretty good. Am I missing something?
Yes clearly its the integral over time that matters... DLI not PAR. But we are talking about a heuristic for new growers to help dial in their setups. You might be able to get a lb in a 4x4 filled with CFLs but no way in hell that is gonna be as efficient. No way you are doing that under 450watts. I think in the early indoor days 1lb per 1000watt HPS is also the standard target. This is all about efficiency and I would say time is also part of this. Most people are not trying to veg out plants for a year, they are doing SCROG or SOG and flipping to flower as soon as the canopy is filled.Grams per watt is irrelevant when u can veg for a year under cfls and grow to the ceiling.
Maybe I misspoke, I thought said the SF4000 should be plenty fine for a 4x4 and even a 5x5. I had never heard of a SF3000 before today but it sounds like its right in the middle of the 2000 and 4000 in led count and watts so 4x4 is probably the max tent size for it but not optimal. The only time I referenced a 4x8 was in the context of my dual SF4000 setup which is drawing over 1100 watts.You said the 3000 originally would be ok for a 4x4 or 5x5.

Nice lookn so far man.. Whos version of the stardawg u got( breeder)?Waiting on a new light to come ffrom spiderfarmer sf3000 ,love the tent fabric is real quality table is about 1ft short all way round tent ,so just under 2mtr x 2mtr.Plants are 28 days today start of week 5 .Thinking of doing something old school after next set View attachment 114555View attachment 114556View attachment 114557View attachment 114558View attachment 114559View attachment 114561View attachment 114560
480W is what HLG recommends for a 4x4. I run 480W and usually pull over a pound per grow (1lb - 1.5lb) which is plenty for me. IMO, though, you get much better results with 480W of strip LEDs than QBs.Doubt it, in a 4x4 those two 240 drivers are rated at 240 watts max, that equates to about 30 watts a square foot.
