1800 watt LED full spectrum flower room

Hello I am going to be flowering a 5x7 room with 6 300 watt full spectrum LEDS. They have 3w led chips.

Will this be sufficient? My plants are scrogged/trained to take up about 90% of the surface area of the room.

I saw some talk about full spectrum flowering not being enough, and that you needed a supplement HPS bulb, is this true?

Looking for any input

Hope you haven't bought those yet because I fear they are mars hydro. If so don't worry to much they will grow but after a few grows you will start getting diode burn outs. They will send you replacement diodes(you do the work) but I would replace them with COBs once you start getting burn outs.

BamaBoyBeRolling is absolutely right. COBs LED lights are the way of the future, man. At least the immediate future. Easy to build, easy to maintain, pleasing spectrum, and they are efficient as hell.

My tax returns just came in, I know what my next project is .

Not mars hydro those are the 5w chip ones and they're also a much cheaper Chinese build than the ones I have. Different brand.

Got a link to a good cob to buy?

you`ll want something like

12 x 300w cob chips warm white
12 x 150w drivers

heats sinks and probably some fans

I find the best way with cobs is to get 100w to 300w chips you can go bigger if you need to think you can get a 2000w cob off the shelf now days

Then I put the heatsinks, drivers and everything into an air cooled hood

That way I can use the in-fan or the out fan or an extra fan on the light

Way less noise even when compared to using say 4 x 300w cobs being driven at 150w each with 4 small computer fans for cooling

using an old hps hood is the way to go I think much easier than building your own casing

Shop around mate cobs from 50w upto 2000w are pretty easy to get now
