First time build for peppers

Yes some real heavy hitters. I like peppers from all over the world. I like mild peppers too, the hots are just more fun sometimes. Lol. I usually grow 1 kind at a time and do about 4 plants. Then I make chili powder and hot sauce for specific chili's.

Pretty purple looks awesome! I had some purple jalapeno and purple Serrano's in the outside garden last summer. Made a super cool chili powder that I put in glass salt/pepper jars. It's pretty purple.

If you ever want some seeds just let me know man. I get plenty and I like sharing. Especially with people who help me with my led project. You've already earned yourself some heirloom jalapeno seeds.

What kind of hydro do you do? I played around with DWC with great success.

I love me a pepperoni sandwich with a good pepper in it.

I've not gotten to really grow that many to be honest. This will be my first year actually buckling down to do it. Some outside and some inside etc...

Man I would LOVE some seeds! I am all about trying new peppers. I still don't think I've found the perfect one yet. I would like to get with you on some hot sauce and chili powder stuff too. I believe that would be a good way to make use of a greater bulk of peppers.

Well I am most experienced with DWC. I want to try RDWC. I am considering expanding to something a bit less water intensive .. or something shallower.

I want to maybe try pvc tube setup for my greens.

I just found these strips from reading other awesome posts here. I think I will get 3 of these lights.

SI-B8VZ91B20WW - 3000k , LT-FB24B (288 Diodes, 16 Series x 18 Parallel, Voltage = ~48V, Max Current = 3600mA)

Looks like they run at 2.24 amps at 46 volts. So to find my driver I do 46x3=138volts with a current of 2.24 amps. This is where I get confused on what power supply to get. Would I need a HLG-480H-C2800?

Looking at these heatsinks. http://www.heatsinkusa.com/2-079-wide-e ... -heatsink/

That 2.24 is just the test current that Samsung used to get the values they published on their data sheet. I'd suggest running these at about 75% of max. Max is 3.6A, so you'd be shooting for around 2.7A. If you're running them in parallel, the voltage will stay the same and the current will be added among the strips, so you'd need a driver that could output ~48V and is capable of supplying 8.1A.

The HLG-320H-48 lands just shy of this and would be a great match.

Also, those heat sinks are perfect.

Awesome! Thank you, 2.7amps it is. Could I run them in series? Is there a advantage or disadvantage? What power supply would you recommend if wiring them in series is allowed?

Thank you Im ordering the heatsinks tonight.

You could run series. An HLG-480H-C2800 is what you'd need. The advantage is you get the exact same current of 2800mA at each strip and don't have to worry about them pulling any more than that. The disadvantage is that it's more dangerous to you since the voltage is ~132V in series rather than 48V in parallel.

Good information, thank you. Yeah that voltage is getting up there. I like the idea of constant current and constant voltage so I'm thinking I'll get the HLG-600H-48A. That would give me some flexibility. Alright, pics will come soon. You all are the best!

What's the best option to mount my strips to the heatsinks? I would like to use thermal paste if possible. It sounds like some people use tape. I'm hoping there is some sort of clip to mount to the heatsinks. Then apply my thermal paste to led strip and then snap the strip into the clip mounts on the heatsink.

Thank you!

Strips come with holes you can use to screw them onto the sinks, I would recommend this with large strips running higher than nominal currents. You can use thermal tape but personally Id feel more secure with paste and screws myself...

Also check out this driver, you could run 2 strips / driver at about 110w / strip.

HLG-185H-42A, its adjustable up to 46v and is a great 'bang for your buck' driver imo.

There are benefits to having everything on one driver, but also drawbacks, single point of failure, etc.

They do have holes I attached a few of mine this way. But its a lot of work. For all the drilling etc.

I drilled mine for all 16 strips. But a warning.. they have to be perfect or else strip fitment will be problematic!

A small washer will help a lot if your holes are a little off. You can see what I did here in one of my pictures.

Unfortunately I got the wrong driver for that single strip build above and it will only put out 1.4A which is less than I was hoping for... Ordered a new HLG-60H-24a which should fix the issue...

[Sonnycohopie]

Ordered my heatsinks today! Yay!

Would this thermal paste be sufficient for my build? I was going to order 4 of these. Thank you in advance.
