Because 90% of riu users only grow garbage and very few people grow danker shit then "he" lol. https://www.rollitup.org/t/strange-deficency-what-is-it.911493/page-2

Because you're wasting electricity by being a Luddite. There are objectively better ways to achieve the same results, and willful denial is the definition of stupidity. You can talk up this "my garden" line, but that's unscientific and a waste of your money. Why not use LED? It's the best source of photons ever devised at this point. Light is light, photons are photons, I'm saying that you are using an obsolete way of generating them. There is actually a right and wrong answer sometimes, and 25% efficient T5s are the wrong answer.
Don't be proud of being wrong, COB guys rip on everyone because we're doing everything we can to push the industry forward, to be met with "that doesn't work for me because I'm cheap and don't want to build anything". The truth hurts.

Holy shit i just read your reply from another thread. Im going to go as far to say that you won't be showing us with any lab results, will you? Your bud is nice. No better then most people on this site. Thats the truth.

Mongo you are the saltiest dude on this website under Buck, (this is Queece by the way oh shit wuddup). We are in the business of generating photons. You are essentially using Thomas Edison's light bulb because you are afraid of being wrong. My chronic is balls-out incredible, anyone with eyes can see that. I use no air conditioning and bulk hydroponic nutrients to achieve that. If you're going to talk about g/w, you need to factor in your mini-split if you want to be honest. This is 1115 watts from the wall, fans, light, everything. You tell me this isn't impressive for less wattage than a space heater? That's absurd. Your methods are unsound. It's lonely at the top.

if you think of it in terms of delivering a hundred pounds of nitrogen/acre (as you would for something like an organic vegetable crop) you would need to start with 8600 pounds (on a dry weight basis) of cow manure (because there is a loss of mass and because the compost is only 1.7% nitrogen). The greenhouse gas emissions are the equivalent of 0.74 lbs CO2 per dry lb of manure. That means that the “carbon footprint” of the 100 lbs of N in compost fertilizer is 6,403 lbs CO2. That is 14.6 times as much as for synthetic urea fertilizer! It is the equivalent of burning 331 gallons of gasoline!
PS: by the way i farm both organic and synthetic
There are actually very few published scientific studies about greenhouse gas emissions from composts, but the two that I have been able to find show that around 2-3% of the original carbon in the manure or green waste is emitted as methane (21X carbon dioxide in GHG potential) and there is also a little nitrous oxideas well (310X carbon dioxide in GHG potential). That doesn’t sound at all bad until you do some math with the values in these publications.

I have no methods. I just garden. I don't even know who Queece is. Whats a Queece? Again your bud is as good as most people on this site. Again that is the truth.

I'll concede that point to you, but I grow that quality for less money than anyone else on this site. I'm saying what I am for the benefit of the community and their pocket book. You can waste a lot of wattage trying to achieve what I achieve with less effective methods, or you could take a hint.

No thanks. Im ok with my current lighting. We all know cobs are doing great things. Im just going to wait for the HPS ban thats coming in like 90 years.

I just did some calculations on the new Ceramic HPS. I digitized the spectral power distribution chart and calculated LER to be 221lm/W.
They claim it's 34000 lumens for a 600W lamp so total luminous efficacy is 57lm/W. That gives it a radiant efficiency of 57/221 = 25.7%.
84% of the spectrum's power falls within 400-700. That gives it a PAR efficiency of 0.84*0.257 = 21.6%. (note: see edit)
The spectrum looks nice, but if these calculations are right, it looks like it will probably produce lower yields than old fashion HPS.
Edit: I'm obviously missing a lot of the spectral power distribution in the far-red and infrared.
I'm not sure why they don't show us this. Either way it doesn't really affect the radiant efficiency calculation since the luminosity function is negligible in the FR anyway.. It does effect the %PAR calculation obviously. Adding in the missing FR/IR part of the chart would make PAR efficiency lower since a smaller percentage of the power would be within 400-700.
Based on these numbers alone, I don't think Ceramic HPS has a great future.

You cant grow that with a T-5..... Its all about photons not plant health and gardening. Beautiful leaves by the way for late bloom!!!

How big and how many TVs you own? Computers? Appliances?
What kind of car and how many? What's the gas mileage?
Do you own a motorcycle, ATV or boat?
Point being if you have bigger or more TVs than me you are stupid for running more electric than me.
Is your car newer and get better gas mileage? No. You're stupid.
Do you have energy efficient appliances?
All arbitrary questions that are not relevant to a person's intellect.
A 4 ft 8 bulb fixture is on par for a gaming computer and other small appliances.
I would bet a $100 bill that your the type of ass hat that is saying that about wasting electric but still have cfl in your house. How come you haven't upgraded to led yet.
Unless you have solar on your house, geothermal heating, and on demand water heaters you have no place to say anything.
Its not wasting electricity if it does the job.

Take care of the plant and everything else falls into place.
That was t5. Three of them in 15 inch pots. Two of them got just under three feet. Colas as big as pop can and about 18 inches long.
They were autos to. Lol. I like going against the grain every way I can.
Thank you. They were in living soil.
The last couple pages of my thread has quit a few pics. I would load more but my connection is lagging.
