Look around. We don't use Cree, Bridgelux, and Citizen just due to brand just like an HID guy doesn't choose Hortilux for its brand appeal. It outperforms solidly.
250w of HPS will yield nothing in comparison with 241w of COB, which is comparative to 600w of HPS if driven well.If he has an extra 50 bucks he should buy a 250 watt hps setup.
Agreed. Heat is definitely a factor, but in my case, I need the heat because my 5x5 tent is in the garage. From what I've been reading, I'm not the only one who doesn't mind a little extra heat during winter months.
I finally broke down and bought a real dehumidifier. Powdery mildew has never been a problem during veg, but it has shown up later in flower. Plants are probably weakened by their natural cycle and more vulnerable to attack. Cranking up the dehumidifier from "comfort" to "continuous" when lights are out is a good preventative measure. Good air flow is also essential.
I've never had an issue but I grow only in the colder months inside, my ventilation is controlled by humidity as well as temp, I typically have to turn on the humidifier

I was looking at epistar and still trying to figure out why cree is 4 or more x the cost for the same wattage. Is there a huge difference in output and efficiency to justify the difference. I'm asking you Olive as I assume you've done the homework, you seem to have a shit load of time on your hands lol.
Never once talked shit on Epistar. I am not sure about how it works, though. I don't have the data for comparison.
PPFD would be best measurement.
I know you didn't, for once I was asking a legit question, I know, it's confusing lol. No disrespect about the time either, just know your here a lot.
I'll have to find something using EpiStar's PPFD output in a square meter using what wattage to get an idea it.
I have been looking at lm but look at watts first to kind of compare apples to apples and they seem close but yup lots of charts lol. A cree chip here is double what they are in the US so I've been trying to lower the cost of the build. If I was picking A versus B I would think watts would be the starting point wouldn't it?
I can look as well, just thought you may have already. I'm not rushing in to this as I really don't need to run anything cooler for a bit and getting pretty good crystal coverage using T5's and HID together, just thinking it would be a cool project when the snow starts flying and I hibernate
.
If they are expensive where you are then order them in from USA. My last LED I bought CLU058-1825 Was $60 USD and $20 postage from USA. If I bought it locally it would of been $140USD
Well that's exactly what I'm saying. Yes then the 9000 lm would be the better choice. Same wattage more light, I just started comparing and honestly I'm not seeing a huge difference. I'm not saying the Wattage makes them equal but it's where I start the comparison, then look at output.
Yes I can order them from the states but it's the currency rate that also raises the price, $60 is $90
.
I just checked digikey and they were $102 Can. But that was a 20 pack
. I only checked the one but as I delve deeper into this I just get way more confused :] perhaps I should just follow the herd as that seems to be the path taken by most .
