Not knockin the light, I'm sure you can get some good bud from it but looks like you're actually talkin 300 watts actual power from inexpensive Chinese cobs. Cover about 2.5 x 2.5 feet in flower, maybe more at lower levels. And a indisputably cool wife! lol

Thank you about my wife :D . And yes i do realize its only 300 watts actual draw ..just more curious about the outcome mixed with some blurples. Tent size is 3x3x5 with this light added i would have 1000 actual draw power of light

1000w in a 3x3 is plenty of power, I'm sure you'll get beautiful buds. Keeping the lights as close as possible will also help ensure you get the best intensity and penetration you can.

Merry Christmas!

700w of LED of even the cheapest kind is more than enough for a 3x3 space.
I don't see the point of buying extra if you haven't already ordered.
Not sure if your wife bought you the current lighting of if she bought you the extra cob lights?
Anyhow adding another 300w is a just more electricity to pay without much extra gain unless you plan on supplementing co2 too.

I actually have a demijohn and use yeast fermentation for CO2, but most likely im going to get rid of one or 2 of my blurples and eventually switch to all cob , and use my blurples for my wifes succulents

So 50 to 60 watts per square, what kinda yields would i get from autos, using megacrop only in 3 gallon fabric pots? in soil ,constant 24 to 27 degree heat ?

Well yield is a much more complicated issue man but i can tell you that with 1000w you’ll more than likely never reach 1 gpw because the space is a limiting factor, co2 availability is another. Even with 700, still these are your limiting factors. Plus with autos you cant even control the veg time. You should think in a way that maximizes your efficiency so you can get the best out of your equipment.

Buy another tent and throw one blurple there and keep one in your current tent and when you have the chance you can replace them with qbs or cobs. Thats just my opinion.

Very easy to replace the cobs with bjb holders and Citizen 1212 or 1216 (preferred). Drivers are ~36v 1500ma. 4 of them will blow away the original 6 and use 100 watts less power doing it. Converted 2 6 cob lights to 4, very happy. Lux value almost doubled.

I use Chinese LEDs and have gotten much better results than with T5 CFLs. It is pretty much in vogue to bash anything from China but some of their stuff is not bad at all. I expect, with that amount of space, you will be pleased with the results.

Full spectrum for me has worked very well in both vegetative and flowering. I would not be adverse to trying a select spectrum in flowering but haven't done that yet.

One thing is for sure, what counts is how it works in your unique set up and only trying things can determine that for sure.
