I thought this stuff was crazy also. Then I switched to high intensity HLG LEDs. Now I HAVE to push up to around 2-2.3 EC in flower or else ill start getting deficiencies. I've tried with multiple lines of nutrients and 2-2.3 EC is what it takes.

I have a couple of Autoflowers in my veg room right now and I tried feeding them at 1.0 EC and they shriveled up and started getting real light and yellow. Bumped it up to 1.6 EC and they're thriving now! Before LEDs 1.6 EC with Autoflowers was unheard of for me.

reverse osmosis
This is the sme kind of pest don't feed on high BRIX argument. Osmotic pressure is not a set point. And each plant given its health will react differently. Further more, not all sources of Osmotic pressure is the same. And High EC alone doesn't not mean reverse osmosis will occur.

I have run 3 different industrial grows... starting EC is usually 1k for heavy feed plants like cannabis in my nutrient programs, with boost unto 2k range.


Long term potted plants aka moms are an entirely different story as they don't go through their entire life cycle.

I think he was answer someone elses question on what to do if their starting water's EC is real high. He suggested using an RO filter...

water softeners can be tricky, some if not most are cation exchange based.
the sodium they ad to your water can cause problems.

RO filters for well or city water is totally a thing if your nutrients require it.


But osmosis, is how your plants takes in nutrients. The osmotic pressure caused with high EC can damage your plants and actually cause then to dump water and nutrients through its roots versus uptake, but this is not a easy scenario to cause. But it happens

Ok so a young friend of mine who I introduced to growing and got going, has ended up becoming my new lover
Sounds like grooming...

Anyway this place pays big bucks to belong to some pay-for-access pot board where he has been "studying" hence the defoliation, flushing and 48 hours of dark before you cut etc. The craziest thing he has told me, is that they want him to grow close to 3 E.C. WTF? Does anybody actually grow that high?
Yeah 3 sounds mad!

Takes a special kind of legend to quote somebody and add histerical edits to the actual quote. You sweetheart, just happen to be that kind of legend. And that, you can quote me on.
Lighten up!... would have been funny without editing it... either way sounded a bit dodgy.

Yea - you're still not getting it.
You misunderstood the original comment you replied to. And now you're misunderstanding my pointing this out to you.

Nobody asked what osmotic pressure was or does. Go back and re-read.
Thanks.

See:
RO = Reverse Osmosis (filter)
excuse the confusion, i may should have added the word filter too.

ah i see

ok, still

reverse osmosis can happen with High EC which tends to affect osmostic pressure.

yall enjoy your black panther party

Ok, I actually had to look it up, I thought 3 EC would be higher but it's 1500ppm. Still, pretty high if you ask me. Then they add boosters.
I was gonna say I get up in the low 4.?’s when pushing the production room but that’s on a monocrop of tried true genetics I have slowly worked my way up over several runs AND not all strains will put up with it hahahaha

You can run EC that high with the right set up...i.e. precision irrigation, fully automated, constant monitoring of EC levels in your medium, etc.
I know Jungle Boys run EC levels that high but their rooms are state of the art. Would definitely not recommend for hand watering...sure way to fry your plants if you ever let your medium run dry.
Yah the irrigation system is key, I have tried hand watering the same solution from the res and they don’t like it, think it’s cause I have the system feeding several times a day giving roots time to dry in between And not a heavy saturation a “daily” watering provides. I run in the low 4.?’s in production monocrop with the trolmaster irrigation system in coco pots following a “crop steering” style feeding schedule with great results
