LED and BUD QUALITY

yield is a function of surface. Quality is your skills. In my book. I'm talking about efficiency here.

You could fit a rotary garden in your 5x5 and yield 3x of the same quality. It just take the skills and the knowledge to do it.

The thing I doubt , that why I ask, is 2x1000w is not enought.
It is still garbage. That thing's purpose is for yields nothing more. Quality is a function of experience and genetics. Doesnt matter how efficient it is. LEDs are more efficient than HID and look at how divisive opinions are. Thats something chad would buy lol.

Well if you want to overlook the cost effectiveness of leds. Their longevity and not having to replace bulbs. The lighting from every angle instead of one source with a constant shadow effect, dimmability, as well as penetration capabilities, sure, all the leds advantages disappear.

Youre gonna put 288 plants in that setup with 2000w? Well then, you will certainly have us all watching.
It's easier to replace a bulb than a LED! And since the wheel rotate,the lighting is relatively balanced in the canopy. And no, HPS bulbs are and have always been better in terms of quality/price. Yes led are most effective now but not by a large margin we are talking about 33% for the best vs best.

But no I'm just thinking about it. I think theres a lot of potential.

Those who think that quality does not go with quantity are wrong, it comes from the idea that overfertilization reduces quality. However, I was not talking about overfertilization but about optimizing the growing space.

It's the grower who makes the quality, no doubt about it I think.

But it is the space that is the quantity. You'll try to weigh 2.6 kilos in my tent!

I remember seeing those rotary things in the back of High Times years ago, along with those fake buds and funny grow chambers whose name eludes me now. It always made me think of NASA growing weed on a space station, I don't think they would be that efficient down here on earth though.

Not a lot of grower tried the old model, but I heard it was a pain because of the recirculate irrigation. At that time most of us were in the learning curve too... I first see that setup in 2009.

On paper it looks great. In pratics, I don't know but I would take the risk because the reward is huge if it works.

Hps have not been better quality and we are proving that everyday with current commercial operations. I grew with HPS/CMH for a very long time and I can confidently say the highest quality product ive ever grown or seen has come from Led, it’s no question. And thats a large margin by the way 33%, huge actually. And it only grows with the CONSTANT diminishing return of hps. Not to mention consistent ballast replacement a minimum of yearly to optimize performance. Youre comparing swapping hps bulbs a minimum of twice a year and a ballast yearly to hope for 33% LESS efficiency. Why even mention its easier and cheaper to replace hps, of course it is, but you have to do it all the time. Leds last forever in comparison, many are warrantied 5 years. How can you even make this comparison?

You are making assumption on different measure when theres a lot of factor involved in the quality.Temperature,light intensity,dli,vpd will all play, did you compared with equivalent measure.... I said hps where better price/quality, or cost-effective. Concerning quality related to spectrum thats a stupid debate. The effiency doesnt play a role at all.

Not going to say led or hps are better for quality.

Theres a bit of a language barrier it seems but lets be clear, are you saying for quality AND cost effectiveness that HPS is better? Because if so, theres just heaps of data to prove that wrong.

Theres a smaller model that would make more sense with 2x1000w . can fit 288plants@4plant per sqfeet in 6.5m2 and I GUESS the intensity should be close to 650umols/m2 with an average estimate of 400g/m2 would give about 2.6 kilos every 60 days.Thats all theory of course.But pretty sure I'm close.

Thats what I call effiency. All this on 2m2.

Now I let you figure the control you have on this with a cooltube and drip irrigation.

The advantage of LEDs suddenly disappears. And it industrial grade.

Hope it gives you some creativity.

LOL, waste of time and $$. Hang a HPS in the middle of 4 large trees. Done.

My 2c on Hid v led?
I like Hid, even still I think plants love it and it's a source of heat in colder climates, however they've been outdated in terms of light intensity and efficiency.

I know from personal experience it's better to use led + run a heater, it might cost a bit more but it's a fraction on the return for that little extra.

Depending on your purpose and climate hid imo still has a place, where I am 250w led isn't going to work it's too cold and humid.

A 250w hid ime radiates enough heat that it's a cheaper option to some personal smoke when/if it's cold.

I frequently read about led not having the same penetration but I've not found this, ive a few plants that produces dense nuggets top to bottom that I just didn't get with hid

No larf, fyi I don't defoliate after stretch and only if it's necessary.

Hid wouldn't be my 1st choice but i wouldn't write it off either.
What type of heater are you using? I don't think its possible with a tent without causing a huge fire hazard. Low temp has always caused me difficulties with LED.

From what ive seen those that gave up on LED didn't put in enough effort figuring them out. It was hurting their pocketbooks to continue. It takes some getting used to. The 1st thing to change is canopy/Room temp. This can vary a bit but not much IMO 85F is what gives me the best results under LED. Most never altered that and used the same canopy/room temps as HID.. The feed can also need some tweaking. When it's about $$ the time to learn something new hurts the business. Instead, learn on a smaller footprint before swapping the whole room. The business can continue uninterpreted while you learn.

i grew trees for many years with the plants in a checkerboard pattern on 6 ft centers and a bare hortilux mogul socket 1000 watt hps dropped in between every 4 plants. so each plant was getting 250 watts from each bulb but 1000 watts total from 4 bulbs. except along the walls where i used 600's for efficiency as they were projecting into 1/2 a sphere instead of a whole sphere.

i've been thinking about how to create a similar vertical set-up using leds.
