I wouldn't ramp up your lights just yet. Not for seedlings...

Hey guys, I wanted to stop and offer an update. Out of the 5 I planted, 4 have broke soil. I have some pictures and will provide more details in a later post. This is actually going to be more difficult to do than I realized. One thing that jimhendrix1 mentioned earlier on was the importance...

First, context. The following was published by the same media outlet that said this regarding Trump's conviction: Political vengeance has a spiraling momentum of its own. Now the subject of this post. Regarding Scott Ritter being denied the ability to fly to Moscow to they are talking...

Thank you, sir, your response is really helpful. I have gone through a lot of your previous posts, and I can see your participation in many professional-level issues, which is great, and I also thank you for replying to me. I saw that the Vesta Gen1 is still available on Digikey, and the price...

Here is the latest build . 263 watts of lamps 24 watts of cooling x 2 apv 12-12. The outside lamps are Cree 3070 cxb,@2700k drawing 50 watts. They are being powered by 1500 milliamps drivers. The center lamp is a Vero 29 which I have under driven using 900 milliamps. This results in a 37 Watt...

This is my latest attempt at recycling other people's crap and building awesome flowering lamps. The abomination draws 170 Watts. There's two Cree cxb one on either end driven at 1500 milliamps drawing 65 w each. They're sitting on an Arctic 11 heatsink cooled off sharing an apv-12-12. The...

We get pretty spoiled with HLG. Did I tell you what they did for my little 250W Veg Pro? The light had some paint flake off. I was stunned. So I called HLG and they were stunned too and I told them I was running her in an 80% humid environment; my clone tent. They said OH we don't conformal coat...

Got the plants in the ground yesterday. I just brought them outside when my stepdaughter decides she wants a paddle board. Her and my wife were looking for one the past few days. She finds one in New Jersey, about 4 hrs from us. So we slapped the plants in and headed out. It felt rushed, and...

By upgrading Samsung’s highly successful 2835 packaging structure, the LM281B+ Pro delivers an exceptionally high degree of reliability with a surprisingly long lifetime. The new structure increases the temperature cycle to 500 cycles between -45℃ and 125℃* — more than double that of the...

Isn't the bridgelux hort line called thrive..what's your opinion on those; and additionally on the new EB3 series? Other than efficiency has anybody looked at who has the best spectrum for plants from the big boys?

Can you tell me more about the anti sulfurization of the pros? What does it consist in and what difference to standard 281+? Its not a gotcha, im genuinely interested as im looking into making some boards with 281s and appreciate any info them. Re "the horses/samsungs mouth": Im not convinced...

My case and point... K series... 256 281 Pros ...~$11....hell you buy enough of them you could get them for $9. 5630's are dead. 2835 are the present and future. Even 3030's are on their way out essentially. Pros have 2X the thermal cycling ability than the regular. Also pros use the best...

When you keep saying 561c strips...hard to read when a person knows what is an actual 561c based model. That's not a model of strip at all. Multiple samsung strip models at the time used 561c's. Not just the F-series that you are probably attempting to reference. With that said, 561's are...

If you have done that its way way way too much. The 12% is the percentage of active content in the bottle. That pecentage is only displayed in acrdance with the saftey laws for corosivs ect it isnt any thing to do with directions of use, just the percentage of the corosive chemical and the...

Coming from a mech. eng. background, I must admit, failure modes are often key in design. What are failure modes? We sit together in a team and come up with all the ways a device may potentially fail. Failure Modes - Water pump relay gets "stuck" closed - pumping water when it should be off...

No, i was saying just put it in as is, i dont wanna advice anyone to saw things in half even though it looks like you could reasonably do it if technical minded. But just dim it down a bit. Looks like if it fit. Since all rows light up the same id just write off those diodes and use it.

Wasn't sure if rocket was referencing using it as is half power as to not trigger any other diodes. If I can indeed cut it in half and use it within the 1-50% on the dimmer, then that would be great. I'm not entirely sure how these diodes are configured on the board. Looks like it's just 1...

Dude, there are several diodes which are out on the left board. As Rocketsoul says, just cut it in half an discard the faulty side. Then run the positive and negative to the positive and negative on the driver an run half the power. You could probably use a wattmeter to know what wattage you're...
