Okay, so it's most likely an overfeeding problem...Nitrogen in particular. Noted. Thank you!

Greetings Rollitup ! I have a question regarding my 2 week old plants here in DWC buckets. I am running two plants in 5 gallon dwc buckets. One of them is under a 120w LED and the other CFLs. I am noticing that my dwc plants have some leaves that look twisted and deformed...more so the one...

I am leaning toward this decision. The +6% efficiency is a big enough number. Thank you for the confirmation about the driver. Will go ahead and process my order with confidence now. I will document my build...I still need info about building but will look at the parts and see if common sense...

One thing I just noticed about the CXB3590 is that it has a maximum power of 137 Watts...would two of these be suitable to run with a single Meanwell HLG-185-C1400A driver? or would I have to dim? On second thought, I think I'll go with CXB3070s with AD bin...what do you guys suggest?

Thank you so much!! I will go ahead and send my order request to Jerry. I hope to be able to find good parts to build a frame..I have gotten good ideas from some threads. By the way, does anyone have experience working with chrome coated plastic? Would I need a drill press at all to mount the...

Thank you for your reply! very helpful information! This clears a lot of things out. =) I did some reading following your links and am now looking into the CXB3590's...what would be the top bin for those in 3000k? and would they be mountable on the alpine 11 plus fans? I want to make a 4-COB...

Bump? :|

Hey Rollitup Comminuty! need your help with a DIY project I have in mind and want to manifest. :) Keep in mind I am a novice DIYer and I am just getting into this whole thing...please use simple terms or try to describe what you are referring to when answering..thanks. I'd also appreciate it if...

Thank you very much! I will look up those specific models and their reviews. Seems DIY is the way to go. Thank you littlejacob and everyone else who replied. It has helped.

I really appreciate the valuable info here...Thank you. I will definitely do a DIY for my own needs.

Interesting post! I wish I knew what all those values and formulas meant...lol that just shows how bored I'd get studying this stuff...I need a simple formula that works...like percentages...seems I got a lot to learn before I can KNOW for myself what works BEST. I appreciate it nonetheless ! :D

Hmm..that sounds like a huge difference in efficiency and I am interested in DIY LED's....How much do you think it would cost to build the system you described? and does it utilize the "Mcree Curve"? I really am only buying from a manufacturer because I'm looking to get into business....but...

I appreciate the info...What wavelengths ratios do you use ? and what kind of cool whites? 12000k? Could you possible give me some percentages of each type within a 3wx60 light? Thanks.

I believe they are Cree XPE 3535

Yea, it is a nice quality product made by a good company. The spectrum isn't final yet...I am trying to get tips from experts...seems there aren't many on this forum in the area of LEDs...I just did some reading really all over the internet on cannabis websites...like the ones I quotes.. and...

Okay...so how about some pointers on wavelengths? What should they be to have a lamp that would serve in both areas of growth; veg and flower? Why would you choose 4k-5k white light instead of the blue spectrum? I read blue 425nm and 675nm are the best. Here are some quotes: "Most horticultural...

Thanks for the reply...here are the specs of the model...there are pics at the bottom of the individual chips/drivers. They are all 100% CREE brand chips so, this is not a cheap unit. Size 394x218x62.5mm Actual Power 120w±10% Input Voltage AC100~240V/50~60Hz Output Current 630mA Output...

Greetings Rollitup forums! I am in need of some knowledgeable advice having to do with customization of spectrum and proper placement of diodes within a grow light panel to correctly balance different colours. I am currently working with a LED company in China in order to introduce their product...

Thank you all who replied! This is reassuring! I will leave these girls to grow out as much as they can without defoliating...hopefully they bear some more fruit. Thank you!

Yea this is just a small grow...so I guess the 250 is enough light for them. I just hope the internode leaves/buds grow out more as flowering goes on.
