Kelp, fishbone meal and crab meal with molasses - thats only what I need for my soil start to finish. I love Kelp! Technically all my weed is "Ocean grown" :D

I did try 36 hrs for a couple of runs - it sure improved taste for me noticably (GG4, Kosher and Triangle). What I'm trying now is for the last 3 days to give them 21h dark and 3hr lights on. My thinking behind it that light will degrade trichs, but it still needed to produce more during a next...

Got any numbers or may be what chips are used? This is redicilous price for this light... No way this 250watter gets even close to 400w SE HPS...

Amazon may be better choice if you are in US and have Prime https://www.amazon.com/LingStar-Socket-Splitter-Adapter-Building/dp/B01I11QZ2G/ref=sr_1_2?ie=UTF8&qid=1524112509&sr=8-2&keywords=1+To+7+e27+Lamp+Holder

I used to veg for 2 years with 9 and 11 Watts SMD based bulbs from 1000Bulbs and Amazon - really good value untill I discovered Samsung F strips thanks to this forum. Cobs wasn't enough to make me switch from these little chinese made led bulbs for veg that was going for 5-10 bucks each :) due...

it's ok, how about qt. (7g) free shipping then to settle it? p.m. where do I shipping it? :)

You missed that post just like you missed your punctuation, I already admitted that I was wrong lol [... sorry, Im very biased... You right, I heard about that vendor...

Lol, any time my friend, but you going to have to pay $200 shipping or pick it up in person in San Francisco. Lol

I was skeptical at first, but yeah, QB is a step up from cobs, and EB G2 and F-series gen 3 is a step up from QB, but its a bit of a DYI. I have timber and RapidLed cob gear that will do the job just fine for a long time, but QB's are just great, early slates were garbage, but they got that...

Mars and vipar does get good reviews too :) depends where you look. Good revies does not mean its what advertized, sorry, Im very biased... You right, I heared about that vendor...

Alibaba - land of the fakes... Gotta be very careful, and I would bet a zip of my best GSC private reserve that it's not 3590... I do not trust Chinese - period.

Sorry bud, but you gonna have to use search my man, it's all here, gotta do your research... I charge consulting fees when I have to spoon feed ;)

https://www.digikey.com/catalog/en/partgroup/f-series-gen3/67179 They are few folks on this forum who made similar set up. Look it up

20xf564b with 2x 480h-48b 20x1" heatsinks around $500 + $200 Now double it for $1.5k 20 strips at 1a will cover 4x8 very nicely 950w). 2 of these strips equal exactly 1 qb288 just to give you an idea, 20 strips is equal to 10x qb288 :)

3x 1212's ($15-20) driven at 0.5A each on the 140mm pin heat sink $20. HLG-185H-C500a $50, total inclidung miscs should be around $100 per engine. I'm not exactly sure, but I'm under impression that this engine has 50%+ efficiency. If you scale up - you can fit 3 engines on this driver and that...

Here is a pic of the Triangle kush that was grown at 58-62F nigh and 70-75F day under V29's, the rest of the plants was getting 65-70 nights and 70-75 day and not even close to have any purple at all. I assume sub 60's is what it is...

Looking around, it looks like there are some good options from some of the Chinese suppliers...

1300W of blurple in 2x4? yeahhh, right...

850W over 4x4 Samsung F564B. I also run RapidLed gear, Trimble and 4x qb288 in other tents.

Pure POS - 140W draw lol
