Share pics of your wiring/electrical area outside of your tent where your drivers, meters, wiring/splices, surge protectors, etc. are all setup. Any tips to save heartache, time, money or burning your house down? Beware of? Maybe if we get enough examples this can be a sticky or very useful...

So far the only side by side test I've seen was done by Migro. They claim the average yield of an HPS is 0.5 grams per watt and 1.0 grams per watt for a quantum board (Samsung LM301B). Do you agree with these numbers and where would you position a standard LED light?

I'm helping a few people grow so I decided to create a series of infographics rather than overwhelm them with unnecessary technical details. This one is a comparison between HPS, standard LED lights and the new quantum boards (Samsung LM301B). Can anyone confirm or refute the numbers, please...

Alright guys you got me all excited reading about quantum boards and what not and I think I may have gone a little too far with this. I went ahead and ordered a 4 pack of the HLG 132 3000k quantum board and a PowerNex-HLG-320H-C2100A because people were saying good things about them...

I’ve always used hid now looking to use led but after hours and hours of looking on the net I feel like I’m doing circles. I would like to do diy but I also don’t want to purchase something overly complicated that ends up a mess. I would appreciate feed back from experienced light builders. Cheers

Looking to get my first set of quantum boards, actually first LEDs for a longtime traditional HPS grower. Gonna go Chinese (kingbrite) for budget purposes and trying to decide between these 2 boards. Both are 3000K, : QB288 LM301B with Epistar 660nm - So 36 of the 288 (12.5%) LEDs on each...

Hi All, Long time lurker here. Wanted to gather some opinions from the knowledgeable folks here, if you might kindly oblige. Background: I have completed 4 grows successfully (In large part thanks to wealth of info here at RIU). For the first 3 grows, I used 5 gallon Hempy buckets. For the...

I would just like to share my DIY fixture with you guys as a way of giving back to this community as I have been a long time lurker here. I'm currently on my first grow with my DIY cheap Chinese cob plus monos fixture. Planning to upgrade to 4*CLU048-1212 for my cab as I want it to be a...

Thanks to a collaboration between HLG, @Stephenj37826 of Johnson Grow Lights, @robincnn of Northern Grow Lights and yours truly of ICC Growers and TCDLabs, I'm proud to present what we believe is the first quantum board based overhead light fixture for vertical gardening; Together, we're...

Hey, Y'all. If this has already been covered please just let me know, but I have been searching and haven't found any threads that really cover this. I want to get some suggestions for a good quantum meter. I have come to realize that measuring PPFD is going to be vital to tuning in my grow and...
