Okay.. There's at least 5 overly wrong things in what you said, but I won't call you a clown. It's the definition of ignorant, though. Bwaha, to be so confident while you say these things is definitely more entertaining than a clown could ever be. FFS, you could have just looked this stuff up and realized what I said was not wrong. You asked for this...
First erroneous statement,
In this context water is not a solvent for hydrophobic molecules (trichomes in this case) - oils, fats, proteints etc. Doesn't matter if people call it 'universal' or not, because it matters how it is being used in this context of ice-water hash production. It's used specifically because it will not dissolve trichomes. Ice-water hash is a solventless process. i.e. no solvents are used in a sieve. All verifiable with a cursory search of key terms.
p.s. everything you said in that answer to my question was irrelevant to the only question asked. You gave me your opinion on whether or not to use the machine and two false statement about ice. If i did 3-4 batches by hand, i'd be stirring for 8-12 hours. That would be insane. Even the off-topic answer wasn't rational or useful and more about your unrelated personal preferences.
Second erroneous statement,
You said "ice" is a solvent in the original answer. Ice is a solid. Solids are not solvents. Verify with the definition of "solvent." Not that ice-water hash involves solvents. As stated before, it is a solventless process.
Third erroneous statement,
Ice does not provide friction or agitation in making ice-water hash. It does not improve yields. Ice is there solely to maintain cold temperature to make the trichomes brittle. The friction of the water flowing through is what knocks off the trchomes. Cold temperature prevent the trichome heads from breaking open - which does not require ice, specifically. If ice pulverizes the plant material, you will get green, shitty hash. Watch a Frenchy vid. Since he is not an orignal source, i'll include a second link that also explains it properly -- https://thepressclub.co/blogs/tips-tricks/washing-hash-ice-vs-iceless-water-extraction. Most people view Frenchy as a 'master hashishian' or whatever the fuck he called himself, lol. Calling me wrong is calling frenchy wrong. There are a multitude of sources that can be found to verify this info.
Fourth misunderstanding,
PPFD is not a single point measurement. Its the average ppe/ppf per m^2, by definition. You are using or interpreting it incorrectly and therefore confused by the things I say that are actually correct regarding PPFD/DLI, which will be explained further correcting your fifth erroneous statement in regard to measuring light provided to a plant.
Fifth erroneous statement,
When a light produces 200umol/s PAR (aka PPF/PPE) and is focused on an area less than 1m^2, the PPFD is larger than the PPE/PPF output of the light. For 200umol/s to equate to 900PPFD, you would need to focus the light on an area the size of 200/900 or .22m^2. Solve for X, bud. It's basic algebra. Then, you'd reference this 900 PPFD with hours of operation to find DLI on a handy DLI reference table, or calculate it manually - whatever floats your boat. Since solving for X is a problem, you should reference a DLI table.
DLI is an apples to apples comparison of light provided to the plant. That way you can compare levels of light regardless of size of garden or hours of operation. 35 DLI over 12h (flower) is the same energy provided as 35DLI over 18h (autos / vege), or whether it's an 10,000 m^2 or a 2'x2' tent. The same yield per ft^2 or m^2, dealer's choice, can be expected, give or take an insignificant amount. *Maybe, one duration is technically more optimal than others for the plant to process, but there's been reputable reaserch on this and DLI definitely is the determining factor not hours of operation. Greater number of strains etc need to be tested to know the exact differences, if any, but they are small an insignificant especially relative to a home grower scale.
Source for the 4th/5th error - You should be able to extrapolate all of this from the information provided by the wiki for DLI. There are hundreds of sources to verify how all this jives together and proper definitions of PPF/PPE, PPFD, and DLI. You could look up how to calculate DLI, too. Seeing that is is merely a cumulative total of photons per s per m^2 might help. Reading up on Avogardo's number will help you understand what a "mole" is. There are various sources to verify that dli over 12 or 18 h won't make a difference in yield, or little to none. I'm not wasting any more time on this. It exists. You can find it if you wish. Energy is a currenct of sorts, so if the plant gets a 100 dollars in 12 hrs or 18hrs it's still spending 100 dollars on growth. It should be common sense.
Bwaha, everything you accused me of not knowing or being wrong about turns out to be correct and accurate. I don't expect you to accept any of this. I'm sure you'll have some excuse or denial for all of it, but anyone reading will know. They can verfiy it all. They don't have to take my word for it. Like my answers to grow questions, i make a real effort not to repeat anecdotal nonsense.
All of that and i never directly called you a clown... maybe a couple backhanded comments in there. Once someone is rude to me i'm not too worried about taking the high road, but i tried my best. I also tried to use as few of words as possible to communicate the essence of each error or false claim about what i said. When explaining things, sometimes it takes more than a typical social media post. I can't believe people think a handful of paragraphs is too much. Anything worth explaining takes at least a few paragraphs. i read 100s of pages per day on average and that isnt even leisure, i.e. novels. This is nothing. This is a less than 1 minute read, ffs.
