How I would set up a 4x4 if I had to use boards. 6 boards and 2 drivers pushing right around 600 watts. 4x6 would use 9 boards. I think that extra kick would be good using the 2100 or the 2800 if I was in an open area.
I dont think 4 in a 4x4 is enough. I think you'll get them drop offs of par drastically. Them boards are only 12 x 7 inches so trying to put 4 over a 4x4 I think your gonna lose on the outsides. That is why I went with cobs over the boards but if I had to use the boards I would put 6 over a 4x4 or 9 over a 5x5 and drive them softer for a bigger footprint.
Yeah that makes sense. 3 over a 2.5x6 but there still driven hard so you'll get taller colas under the boards. I'm all about even tops cause it makes it easier when adjust the light height. I hate colas that wanna grow extra taller under the bulbs so you have to keep raising the lights and the outsides suffer or bend them over.
I got 6 boards with the slates. Gonna run them long ways across the short sides 8 inches apart down the length of the 2x8.
Ohhh looks like I have a new want!
I have 2 boards in a 2x4 and it is way too much light for the cabinet, well not really too much but more than enough for sure. I think 4 in a 4x4 would kick ass.
Yeah the entire purpose of the led market is efficiency, running more light points at a lower amp is driving them softer giving you more par per watt. Cost a little more up front but I think the end result over the footprint is better as opposed to less light sources driven at higher wattages.
If I had to do it all over I would have spent the extra coin and got more higher amp drivers. Dimmed them down and increase brightness as the canopy gets taller. I dont have any issue with what I have but I always have wanted to run 8 foot plants in 26 gallon totes on 5 foot centers under 2800 mA drivers.
I have 8 or so cobs. I have older 36v cree 5000m cxa3050s they will handle 1800mA and will blind you. I've pushed 41.25v at 2350mA through them on active cooled cpu heatsinks. Just barely got warm. But man they are bright. Especially being white Kelvin every time I worked in the veg tent with them on. When i closed up and turned lights off in the room and leave to go outside I couldn't see shit for like 10-15 mins. They really mean they will cause eye problems. Bc they will. I got a pair of methods 7s its unreal how much nicer it is with them and still being able see. But I pulled them out for this new QB I'm testing. 97+cri 108e 4.5A at 24v. Its 4k. Decent vegging. But they say 2x2 one board free air no sink at all. Its alot thicker than hlgs but i just sint seeing a 2x2 flowering from it. And its loaded with resistors. And they make the same exact board with tons of reds. I mean tons.
I passed up 2 10 box cases of 86 fleer basketball in 87 because the guy couldn't sell BB cards everyone just did baseball there were on average 2 Jordan RCs a box my biggest sportscard miss ever
Check out the conversation I sent see what u think I have used it to relocate many things for many years And never I mean never has it failed
Yeah man gotta keep on top of that, I see idiots posting full detailed descriptions of how their shit arrived.
I stand corrected. Nobody (except Canadians) buys DVD's anymore. Nah, seriously, I know for a fact that DVD and CD cases are considered suspect by the Aussie customs.
