Reddit mentions of Roleadro LED Grow Light Full Spectrum 400w COB Light for Flowering and Veg

Going to piggyback my own question on here.
3x Roleadro LED Grow Light Full Spectrum 400w vs 2x Roleadro LED Full Spectrum 600w White 9-band LED
The cob option should be better, right?

I have that one and the roldero cob also. I would spend the extra bit and go for that. It wasn't much more but way better. The plant under the led stretched to the cob

It's not that you didn't spend enough on lighting, it's that you bought the wrong things. You spent 128 CDN (Give or Take) for crap. These are comparable to your price and you should see a significant increase.

3 a little more expensive but 400w Cree COB LED

This would put you a little over budget but may be your best bet. Canadian Amazon has a horrible selection.

I forget the exact equation for plants per foot but I think it was something like 35 draw watt of LED per squared foot and 1 plant per squared foot. in something like 2-3 gallon pots. Sea of green is best employed with shorter grow times in veg atleast to cut back from what I heard. whole idea is filling in a canopy with many small plants instead of a few big ones. lighting really depends on what your budget is, and what exactly you want to do, and where you live. In canada it can be hard to get ahold of QB and COB set ups but I'd still suggest them. Quantum board LED using samsung strips is really popular and so are cobs, you can get citizen, cree, or vero cobs. QB are the most efficient as far as light output but cobs can be very good too. I personally run cobs but I did not DIY. Which brings me to this. Are you going to DIY or buy a prebuilt fixture. DIY is always cheaper but you need some tools and basic electric knowledge. You can buy QB and cob fixtures that are plug and play but it'll cost you more. I run two CF grow 60W units they use cxb 3950 cree cobs and meanwell drivers, both very popular parts amongst DIY builds. They are pretty decent. I first bought a shitty 200W cob from amazon, it will grow full cycle but its canopy penetration is not nearly as good as cree cobs. It will however pull more true watts for cost.

decent brand 3 year warranty on bulb I believe 7 year warranty on the meanwell driver and has prime- https://www.amazon.ca/dp/B06XFNXLBK/ref=twister_B07DCM7RP4?_encoding=UTF8&psc=1

if you have a little more money buy the 200W version it can apparently grow 8 plants under it with decent results.

if you are a little cheap I got this as my first light the ones I mention above 2 year warranty I think they use cxa3070 cobs mine makes a noise because of dust in the fan after 4 months but it grew prob 2o- https://www.amazon.ca/gp/product/B013QLEYTW/ref=oh_aui_detailpage_o06_s01?ie=UTF8&psc=1

DIY pricing is something like $50 per cxb 3590 cob and a driver that could run 4 of them at 50W each will prob be about $100 then you gotta DIY cut a aluminum frame to mount it on and have some kind of active or passive cooling. Need all the wires tools etc. plus the cost of your time working on it and putting it together, if you have built a computer you can probably figure it out. You can also build 'mostly assembled' kits


EDIT: get something in 3500k light temp so you can run them full cycle and do not need separate lights for veg/flower,

I dunno man, I've got some that are 16 from germination looking closer to what u/WeedBaker posted, and they had a Mg deficiency slowing them down. They've been under one of these rocking at 24h though. Not saying your advice is wrong, but the other guy isn't either.

Based on comments I'm currently looking at getting two of these 400w COBs. They are the best value of $/true watt at $0.90/watt and two would be 400 true watts.

Shoppi g for grow stuff in canada hurts when I see these prices posted! Same light from Amazon.ca... https://www.amazon.ca/gp/aw/d/B013QLEYTW/ref=mp_s_a_1_2?ie=UTF8&qid=1521318478&sr=8-2&pi=AC_SX236_SY340_FMwebp_QL65&keywords=roleadro...

I got an 800w roleadro

Before that I have (and still do have) 2 of these

No, it's one in this style, but I sprung for the 300w version because it was a good bit cheaper. I can't seem to find the 300w on the site now, it may be out of stock.

For a small tent

https://www.amazon.ca/Roleadro-Grow-Light-Spectrum-Flowering/dp/B013QLEYTW

So only one light like this would cover the whole tent ? https://www.amazon.ca/Roleadro-Grow-Light-Spectrum-Flowering/dp/B013QLEYTW/

Get a COB LED. Prices are coming down and they can be pretty affordable nowadays.
