Yeah guys, it was revealed live on the Growtube roundtable. Cyberh_hog won the chilled 450w , it's been shipped and he has an Instagram. "Eric" was the winner of the Canopy12uv. I made contact with him , and I'm programming and testing the controller for his photoperiod before shipping out...

Just touching back on a topic from the last couple pages. Part of this whole giveaway light build was to demonstrate some techniques that I haven't shown yet. Like the cobs on LDDs for the purpose of 0-100% dimming. I figured it might be interesting for people with small grow cabinets running...

more optics talk & dummy proof links on where and what to buy

im still trimming, but initial weights and quality(overall look, smell, taste, and stickyness) surprised with the ChilLED 650w. The GPW and gram per sqft are in COB territory, fo sho. (yield at/or above 2 units in a 4x4)

well done. I can't wait to buy & try some for growing cannabis plants indoors. lol

when i have problems. step 1: remove the pot, if still not working, then step 2; multimeter, dc volts, check leads on DC out of driver(red/blk), if you have a voltage, in this case 216v -ish, & still not working, then step 3; remove quick connects, barrel connectors etc. step 4: check AC side...

it kind of died on the vine. the entire design is a pain in the D to bend. meaning the metal brake I have access to cant really bend these tight corners. And it looks suspiciously similar to the cxp250. I want to work on something that is mine, original and innovative. stay tuned

I have had communication with probably 100 people either here, on Youtube, or IG, about their Cutter Mau5 kits and builds. Thats 400 heatsinks, 8 applicable holes per heatsink, 3200 threaded screw holes. I have not heard a single complaint or criticism about the heatsinks.

@Airwalker16 funny timing. Im actually working on a video discussing that topic. Parallel wiring cobs using: -fuses -current limiting resistors -how to build a current mirror The premise is: "someone" is on a restricted budget. They need light now, but dont want to piss their limited funds...

im not arguing with you. I am arguing with the knee jerk recommendation to simply add more calmag, because a person bought an led light. I think this is an incredibly common recommendation on this topic and I think it is misinformation.. and im not hysteric , im chill as a cucumber. but I...

I would like to offer some testing that I believe pertains to the OPs question. I recently finish a series of videos evaluating 2 nutrients lines: -one with a multiple bottle liquid line offering me full control and the ability to dump a "random shit load" of calmag into my feed solution -the...

Liberally is the word I carefully chose. You said and added "random shit load" i have used 5-7ml per gallon of calmag for the last 10 years under every lighting scheme ive used on dozens of strains. I do the same today, occasionally Ill add some NFTG herculean harvest (CaPO4). From my...

@Evil-Mobo there are so many components and suppliers to consider. I literally got on the computer sunday, designed the file, cut a few and bent them up for a small build im doing for a friend. Im not sure what fits and what doesnt. @AtterStiga 1/8" L aluminum is some pretty strong stuff...

biggest issues. -what to do with all the extra money in my wallet after paying for my electric bill. -what to do with all the extra bud from my harvests with COBs increasing calcium & magnesium, potassium deficiency, etc etc I think all that is bullshit. I used a liberal amount of these...

i wouldn't get too caught up on your geometry and perfect spacing. Look at all these tiny little commercial led grow lights on the market that people buy. Many/most are 18"x18" fixtures claiming to illuminate a 4x4. And a lot of growers do just fine with them. For your 12 cob build (4 cobs...

I was pretty darn successful with my 10 cob kit from cutter over 20 sqft. So 18-20 cobs should work nicely for your 36 sqft area.

im refining the design and calculating cost at scale. its all that i'm working on this week. im really trying to do a big initial run to get them in peoples hands for a reasonable price. -the slots that you see on the tops of the bars for 'perfect' spacing of 3,4,5 cob configs is making each...

https://www.sparkfun.com/products/10747 will do it, for the "i just want to buy something that works" crowd. up to 15a per unit. so you will need a couple. there are cheaper alternatives on ebay and amazon

@AtterStiga Im sorry brother, I did not find the size of your grow space... 'assuming 4x4 ish. You can be successful with 10. but while you are excited and doing the job, you might as well go with 12 and pump those ppf & yields up. a 42" frame allows you to have the cobs spaced out just about...

I appreciate people looking 2 me 4 advice. This profile page is probably clunkiest worst ways to communicate. Q? will not be answered here
