LED and BUD QUALITY

[weedemart]

Still I didnt get my answer where is the lower electricity bills with eficient leds ???

+ dehumidifier + heater.
Its more 700+ 1200+2500w.

10kw of hps is the same as 10kw of led in term of heat output. so if you need a heater with leds you need it with hps.

and you always need dehumidifier ... not when light are turned on but when they are turned off.

Show us your dried buds! I bet they put these to shame. This is with a crappy camera phone. Lets see your led or hps dried bud that even comes close.

@CannaT sooooo unhealthy lol

Dehums most always required, heater ive never had to install. I just have an AC and dehums. And guess what, im saving about 40-50% since i can dim on Hvac compared to any HID grow with my sq ft canopy and im getting better quality with higher yield. HPS is for those who cant adapt. Stuck in their ways and stubborn at best, you precisely.

The browning of pistils in plants can be caused by various factors, including nutrient deficiencies, environmental stressors, or pest infestations.
Not something good...thats why I said its not something normal.

Yet its better than anything youve ever produced in your life.

There’s some great info on this thread… hard to piece it all together amongst everything else though. I’m keen to start moving over to full LED soon, so it is cool to see some of the results people are getting…

We have quite the lot of science deniers who come here to preach HPS and shit talk Leds. It dilutes the goods. Sorry for this, my rant is over.

3rd party would be nice, that efficiency rating is insane. Hard time believing that, and this spectrum chart…what? View attachment 18968075

This is a greenhouse supplementary light, its not supposed to grow on it self, its what you add to sun light for best growth. 1:20 blue/red ratio

That makes more sense.

 

[CannaT]

That makes more sense.

Why you put pictures of flowers and talk about plant health ???

@CannaT sooooo unhealthy lol

From here I can taste that chem notes in those overfeeded buds...I bet they taste like cardboard.
Do you ever grow plant that is low N at the end...without overfeeding them ?
Still I didnt see healthy plants.
Just overfeeded plants with various deficiences and toxicity.

your plants dont even fully ripen, lets see your awesome buds

lowest 3 will be silenced soon.. just continue

That's where @weedemart "4-6lbs per light" comes from – it's mixed with equal parts sunlight

in the absence of arguments, you lead team. Use insults as your arguments. truth hurts.

let s check who started it?

With the industrial devices using UV-Vis spectrometry over the range (200-750 nm), NO3-N measurement for example can read accurately down to 0mg/L in 0.01mg/L increments and can take a reading (inline) every 15 seconds.
The technology is already in use, it’s a matter of applying it to this industry.

They used known feeds, then took readings known to be wrong. Then with the knowledge of what it should of read, calculated the error. They did this with many mixes of the stocks, until they could write a program able to calculate the error, within the confines of their work.
This is done in a specialist lab, to get the N reading within 7%. With a nod towards problems at the extremities of measurement. I didn't see anything about measuring to zero, but they are still working on this.

Earlier I was saying how some experience is needed, to make use of water analysis. They are turning experience, into a computer program. To figure out the truth, rather than measure it.

Perhaps my interest in the mechanics of the situation, isn't going to align with what others see as useful. Which would be a usable output appearing, after their years of waiting. Unfortunately, perhaps, I couldn't wait. I'm here, today, with the lab reports available. Though it's great to see your find, regarding AI doing the computational stuff, and getting a better result than I'm going to. It goes well with the miniaturisation of the hardware, that is close to handheld now. I can see it coming together one day.

plant doesnt need macro fertigation. as long as you keep things in balance it will does what it does; turn energy into photosynthese. It's easy to overthink and start doing stupid thing. I try to treat cannabis like any other plant and dont go outside of the essential.Apply science forget the rest.

Applying science is what I'm talking about. There is quite a bit of work being done on this. No big op really wants to chuck a partially depleted tank away. They want to correct it. Opening the door to constant re-circulation.

As an example of the work going on:
100ppm N can't be maintained. Normally our plants will take the N from solution quickly. Store it. Then move it around until the next addition of N. If we keep the availability at 100N, they will OD. Instead, with constant monitoring, you may run about 20ppm N. Over 24h the same will be used, but supplied at a rate close to what it's used. Analysis of both plant and solution really get this right. It's seen as beneficial, as storing then moving isn't as effective. Nor do we want to chuck big tanks away, as we use far too much P, and when it's gone, We are screwed.

Youre the one calling out my grow as unhealthy which is laughable when you post your own product. The truth feels great on this end.

That is not proof of nute burn. Once you have been growing long enough you will figure this out. That happens whenever I start my fade using RO water. I also noticed it more when I switched to LED using the same feed as I did with CMH.. CMH never had it. I use an EC of 1.2. which is not a level that would cause tip burn. During fade is when I see that the most. It is not an issue to be concerned about.
