Liking what is going on here! I've recently bought an arduino to fiddle with. I want to automate my watering system for 16 hempy buckets in a 4x4. The DIY with arduino could not be easier!

A great way to start is to learn why an LED needs a constant current power supply. Then try to deciper a datasheet and you will pretty much know what you need to know. This datasheet is for the cxa3070. which is a part number.

Yeah its http://parts.arrow.com/item/detail/cree/cxa3070-0000-000n00z230f#QegG Thats the cree I bought and you can search for others there. but They only sell in bulk of 20.

Tried and it did not go through. They quoted me at 34.20 first so I jumped on it and later they refunded. So I think something happened with pricing or something since I thought that was a steal. Decided the 3070 300k would do it and bought 20 from arrow. They haven't arrived yet. I Think they...

So how are the plants doing Supra? :)

Can I ask what program you use for this? I hand draw and hate it becuse I cannot post my ideas. Beautiful designs!

Bought a Carson MagniScope the other day and it was just delivered. I checked trichs and they are B-E-A-U-tiful!!! Can I get jim carry to say that? hahaha I never knew they actually looked so nice to be honest! They were almost all cloudy, no amber so I'm going to let it go till next sunday...

Here is more! Really wanting an opinion! :)

What do you guys think? Blueberry Gum. Lost track of time. Here are pictures! Thanks!! :)

Are you holding those cxa's with only tape and thermal grease?

Great! Which means I'm back to watching the 3000k till harvest before my next led purchase! :) Thanks for the great answer Supra and the study Abiqua!

How are your results coming along mtnstream? I would love to see the plants under the bluer spectrum too :)

Supra, What are your thoughts on high CRI levels vs a high light saturation level? I recently found the 3590 with a CRI of 95 on the datasheet with a performance group of Z2 which got me thinking. But cannabis is a weed correct, in a plant defining sense? So would it benefit more from more...

I am wondering about quality of light now over quantity. I was looking at the datasheet for the 3590 and noticed they have a 95 CRI 2700k in the Z2 performance group!! That is huge! I also found a 900mA driver on alibaba that would be perfect to run the LAMP for one per plant :)...

Here are my plants. The one with the finger is BlueBerry Gum only 5 weeks in And the other is Critical Jack Herer and it is 4 weeks. Here are some pictures :) They are unorganized but I am sure you can figure it out :) The smaller two plants are my maui wawi that I had in the solo cup...

Nice find on the driver! You can look at pct.cree.com to see a chart. It will show you what voltage you need at that amperage. I think you would be OK running that driver :) I use the 4 3050 over four plants each in a 1x1ft scrogg net. Great results!

Sweet! If you would leave it there that would be awesome. I want to see only 3000k results :)

Solely COB? Great results and pictures!

Can I ask who you ordered from? I would like to jump on the Z4 while I can. Thanks! edit: I found it, I missed your first post. To Arrow!

Hi everyone, Here is the update on my purchase. I have been refunded the amount I paid for the LED's. I have emailed arrow about my order with no response? It has been 3 days today no response. Thats all I know right now. Canna
