Using aquarium leds to supplement.

Hello,

I recently got one of the Meizhi 450w lights and am pleased with it. Im looking to add a little more light and I have two Maxspect Razor R420 16k lights. They each run pretty close to 160w

I am curious if they would help or hurt considering the spectrum is 16k and I am not sure if that will promote more Veg growth and slow down the flowering?? I just flipped the plants to flower a couple days ago. I used these lights to Veg with great success, just curious if they would be good or bad to keep using.

I would of posted a link to the lights to make it easier to see the specs but I was too new.

Thanks

Would really appreciate any info on this. The lights have a fair bit of power so I am sure they could help as long as the spectrum doesn't do more damage than good.

The Meizhi light is for both veg and flower. Excells in veg but could do better in flower. With the suppliment 16k lights u use with the meizhi in veg seems like it would veg a monster! Lol. Id see about getting a lower kelvin bulbs for flower to add as supplement than using 16k to help aide the meizhi. I dont own a meizhi but come across users who own one and grow with it and im just paraphrasing from what other users have said

Thank you for the feedback, I will be looking to add a cob for my next light, I have heard nothing but good things about those. I probably should of just went with a 400-600w hps but I was worried about the heat. I am growing in a small space and was already having heat issues with the leds. I am only going to be doing around 4 plants, so the Meizhi and a good cob should be all I need.

I should mention the lights are full spectrum, they have some bulbs down to 3k but overall they are rated at 16k. I can turn off one channel that has most of the blue spectrum. I suppose that would be the best way to go.

I would post a link to the lights but I dont have enough "likes"

Thanks again.

They have single cobs builds and other diy cob lights with frames and heatsinks. I built my own and used my own resources. Diy is the way to go!

I am thinking thats what I am going to do.
Thanks for the likes, these are the lights btw. They are a couple years old but grew corals like mad. Not the right spectrum for sure, but the par numbers are decent.

Have a good one.

I just built a double cob vero 29c setup. 200w of 3500k growing power.

I used to think 4000k would have been the best to grow with. Due to the even blend of red and blue spectral peaks. But, so many suggested I pick the more red heavy 3500k model. I ended up going with it.

Their reasoning was that the 3500k bulbs have plenty of blue to see you through vegetation. But, it's in flower that these lights really put out results.

I would go the same route as you. More concerned about the flower for sure.

Thanks for the feedback.

I made my light with 36x 10w 3200-3500k cob chips powered by 2 different xbox 360 power supplys they have there own switches one runs 200w the other runs 160w and blurps for supplement lighting. Laptop cooling fan. Aluminum square stock . and added in a watercooling system lol. Im guna make another light. 96 watts of led for another little flower box

I'm using bridgelux EB strips powered by a simple transformer less power supply to supplement T5s in flowering. this is a new experiment so I do not know how they will perform but they a more efficient and cheaper than COBs, provide more uniform light distribution and are lighter since they do not require heat sinks when driven at 900ma of less. this is the latest LED technology available and will replace COBs. the samsung 561SMDs they use are being used in quantum boards and some high end LED grow lights.this would be the most cost effective way of supplementing your LED grow light.those cheap Chinese grow lights do produce a lot of heat. my 150 watt HPS light does not produce any more heat than my cheap mars 300 watt (130 watt actual draw from wall) and CMH lights are becoming much more affordable as well http://www.ebay.com/itm/Brand-New-315W-CMH-Grow-Light-Kit-Reflector-WIDER-Range-W-Bulb-120-240V/122585305982?_trkparms=aid=555018&algo=PL.SIM&ao=2&asc=45729&meid=bfe5747843cb4bf2a2215ba02d2297d4&pid=100005&rk=3&rkt=6&sd=272655806270&_trksid=p2047675.c100005.m1851

I used to own that light. Since Its dimmable you should be able to crank the blue channel to 0 and put the whites at 100% and that uses warm white and cool white so you'd have a closer spectrum to 6500k. You'd only hit 16k with the blues cranked up. I think that would be an awesome supplemental light. Add the 120 degree wide optics too.
