The 3 Herijuana's in my outdoor garden came up with a massive mold attack, so half of it was thrown away...
But still a nice result

And just visited the guerilla spot, it was late at night, so just a silhouette for indication, plants reached a height of 3.5 meters!

Soon i'm starting a build for someone in my family, 4x cxb3590 @ 1400 in a small tent, i'll post it when ready :bigjoint:

Hey @Netherfly , love the build. I was wondering what you were using for your power inlet! I'm trying to figure out a clean way to make an input box, looking for something exactly like that. Do you have the info on that part, I couldn't find it anywhere in your thread. If you're using the 240s, you're running a 6A minimum inlet, correct?

very nice8-) clean build. cooling performance should be very good or? how long is this lamp? 80cm or 100cm? how much does it weight?
the pinfin heatsink are 100mm diameter? the dimmer has 2 step?100% and 50%

Thanks for sharing pictures:peace:

Wow! I am curious to see how this performs...

Made a few drawings of a very similar build. Fans/fencepost/pinfins but the drivers were remote. Would love to see readings from 1st HS vs. last in the tube.

Where did you get the square tube?

Nice clean simple build :clap:

hello friend. (I have a good consultations I hope not disturb)
few pots're getting in your tent of 47x47 and liters or gal of them.
I've seen your postings you put 6 and then 5.
you apply some apical pruning?

Looks really nice! Did you put fans at both ends or just one? I've had best luck when using just one fan, to draw heat from the tunnel.

For redundancy i put 2 fans in there, they are running @ only 7 volts, so very quiet... in my experience with these pinfin heatsinks, they only need a little airflow, and all is good :)

Right now i have 4 smart pots of 60cm diameter in the big tent, last grow i topped the plants just once, i'm still experimenting :)


Tonight i'm going to set up a 120cmx60cm tent with softbox and this beast @ a friends, pictures and also measured temps will follow!

after watching again the pictures, i wonder how you had acces to the inside of the bar? how you could mount all this inner stuff:?

90cm tube is easy to reach with my long arms :) also the holes in the bottom for the COB's can be used to reach cables.

So yesterday build the setup for a friend, 3x northern lights seeds are in the ground!

I measured the temperatures of the heatsinks (area just around the led chips) and surprisingly all 4 COB's stay around the same temperature, ambient temperature @ the time was around 22c, and the measured temps about 33c.

The softbox ventilator + variac in combination with the tube light is really a next level silent setup!

And in my own kitchen 2x OG kush and 5x Sugar Punch are nicely vegging:
