Hello All!
Welcome to HughJassBud's Hugh Jass Light Experiment!!
This will be my first thread on THCFarmer so bear with me. The point will be to establish spacing guidelines and a solid DIY guide for using current LED/COB technology to match or supersede HPS technology....if possible.
To begin, I have purchased 16-Cree CXB3590 @ 3500k CD bin. Also, I purchased 5 in 5000k range as well, CD bin. For drivers I chose the Meanwell HLG-185h-700mA variety. I debated this for a while but my mind was made up based on my desire to run the drivers remotely. Running the 72v version of the COB will mean higher transmission voltages and lower amperage as compared to the 36v version. This should mean less loss in the electric transmission from driver to COB. Also, the price on the 185h as compared to the 240h was significantly less expensive. So, it is less expensive to run 16 COB's on 4-185h drivers than it is to run 15 on 3-240h drivers. Your experience may vary if you are using a different supplier. From a power standpoint, these will be running the CXB3590 at 50% power, 50.4 watts. Credit to RealStyles and Supra for paving the way on this subject.
I've also ordered the Ideal Holder 50-2303cr x 21 for mounting the COB to the heatsink. For heatsink I will be using a 140mmx70mm pin style heatsink with a solid 10mm base, pure aluminum. I will include pictures and a details on where I ordered once I have gathered everything together and verified it will work.
I will use a standard, first gen Raptor Hood for enclosure. Currently I run 2 of these in-line with a 6" inline fan and 1000w HPS bulbs in each. All together I have 4 of these hoods with 1000w hps bulbs in my flower room. Also, in the winter, I run an additional 2 x 600w hps in standard sized vented hoods for a total of 5200watts in a 10' x 8' area. With all new bulbs based on the manufacturers specs this should be about 560k lumens from the 1k w lights and another 200k lumens from the 600w lights. Of course, there are rarely all new bulbs in the room and I think these manufactures are generous with there claims.
There are many of you here that are no doubt better growers than me, but when I was doing well I would be pulling about 8-9lbs every 2 months. That was all in Happy Frog dirt using primarily Fox Farm Nutrients. However, work, school, and life have made it difficult for me to be consistent this last year or more. I've got a little more time this summer so I have decided to switch over to mostly Flood & Drain style hydro and just remodel my room a bit so that hopefully, going forward, things will be a little easier for me to keep up with. I will probably drop the 2 x 600 watt lights for the time being too.
On the plus side, I think this lends itself to a side-by-side test better than what dirt potentially would. The tables are perfect size to each go under 1 raptor hood running 1kw HPS or however many COB's get the vote to be tested against it.
Today, I probably should take some clones so we can kick this thing off in a few weeks. You guys can help me with this. Here is my current list of genetics, sadly I lost a few this past year that I'm really kicking myself for. No specific order, just as I remember them:
The White
Watussi
Sour Diesel
Northern Lights '95
'92 OG
Larry OG
Purple Goji OG
Purple Barney
Fools Gold
Scott's OG
Bubba Kush
Xenu
I think that's all I have at the moment. Some of those will probably run OK together if I want to combine them....some will probably fair better in Hydro than others but I honestly don't have a ton of experience with these genetics in hydro accept for Purple Barney and Northern Lights.
My Vote will probably be The White, its just one of my very favorite strains to grow & smoke. Purple Barney is the only one on the list that wasn't a cut from a reputable source. It was the product of a random bag seed *I think*. Whatever it is, I really like that one. It has some weird sweet-diesel-OG type flavor that I haven't had in anything else. Super oily, makes great bubble hash for those of you that like to kick it old school. That will be my second vote because I have grown it in Hydro elsewhere and know it will blow up.
I have never run Scott's OG, Fool's Gold, or this particular cut of Bubba Kush.....they will all be good I'm sure, but they're new to me.
So help me decide! Weigh in on what the first run should be of and I'll get to cloning!
Thank you all for stopping by. I will gather all my diagrams and information on the light I am trying to make and post it later tonight!
