3500K is great for veg and flower. It has been deemed by some to be the best all-rounder. Yes that is why I recommended the light engine - it is very simple to wire it up and the COB is already mounted for you. You will also need a 12v power supply to power the fan, and some wires, and a plug...

...although I kinda doubt he was talking about any of those for his seedling starter light.

They like the movement but not the heat. When your ambient is 87f the air is kinda hot... hence the original question.

You will probably regret it. Just sayin.

It will grow, but not as well as decent LED. Efficiency is not comparable.

Thanks for the info. Sending good vibes his way :peace:

Yeah super beautiful plants man! One day when I grow up I wanna grow plants like that! How many times do you top etc?

Hey Cobby I wanted to ask you about the Active coolers on the light engines... These IceLED fans push the heat down towards the plants, right? Is it possible to reverse the polarity of the fan in order to draw the heat out the top of the heatsink and towards my exhaust instead? I guess pulling...

The Samsung strips are great regardless of how good the Cutter strips are... and so cheap. I'll be surprised if the cutter strips are any better or cheaper.

Agreed. Years of work lost cos of some worthless hater. That should not have been allowed to happen.

I know it seems intimidating, but it is really the easiest it has ever been, and likely well within your capabilities. With a prebuilt light engine (COB mounted on an active heatsink with reflector) all you have to do is; Connect the wires running off the COB to the output wires from the...

Looks sweet. Reminds me... I wonder if that guy @Bobby from Mi ever finished the bar frames?

lol but even then you won't know if they are genuine! In order to prove they are genuine beyond reasonable doubt you will need to have Meanwell's head of electrical engineering come to your place and take all your drivers apart and personally check each and every component for authenticity. Only...

Point taken. I do sometimes ask suppliers to "cook" the invoice for me, but there is a limit to how far you can go with this without getting caught out. Sometimes the customs officials in this country actually go online to check the value of items and they can use their own valuation for...

Hehe exactamundo!

Exactly man! If it was good enough for our forefathers then it's good enough for me! I blame that twisted troll for stirring up all this safety FUD.

Yes you should! CFL's will not allow you to get max potential from your plant. Aim for 35-40W of good LEDs per sq foot and you will be golden. You could run 1x CLU058 3618 at 1.4A to get around 150W for less than $200 (inc driver and active heatsink). Talk to @CobKits cos he is thinking about...

Haha ironically it was the shitty design of the ideal holder that pushed me toward TIM and tape. If the BJBs had been available for 3590s at that time I would have bought some, but they simply weren't. A chip holder that requires an additional adapter in order to use a reflector... now that is...

I already have perfectly good working lights dude. Buying expensive (and heavy) new lights, shipping them at significant cost, and figuring out a way to beat customs charges... all just so that I can use a specific lighting controller definitely seems like a false economy to me. I will not be...

I hear what you're saying but that is not an option for me. Anything valued at over $200 (inc shipping) costs me so much in import tax that it's not even worth it. I am sticking with the DIY COBs whether I like it or not lol.
