That's not an npk ratio. It's different and it's can be helpful. If the ratio is off, you can get leaves like you have. So for the drop in ppm (measured before and after replenishing) means you can feed a little more, a rise in ppm means cut back. This is due to the ratio of water being used by...

I think you are gonna have to run ac in the space. But if you have to do it with fans, I'd make a raised floor/air plenum of 3" with lot's of clustered vent holes in strategic locations. The opening of this raised floor / air plenum is below the new door for this space. At the top of this door...

What are your npk ratio's and total ppm's? When you have to top off, is your tds rising or falling?

Check out Barry Cooper's vid's on youtube. You might get some ideas to apply to your situation.

Everything. Because it will change how I feel. In any moment in time, the conversation I have with myself or the words coming out of my mouth make me feel a certain way. It also works the other way, in any moment in time I can change how I feel by the conversation I choose to have with myself...

So for N,P,K,C,Mg,S The ratios would be 3 - 1 - 2 - 2.4 - 1.2 - 1.5 ? Whereas, Calcium to Nitrogen is .8 to 1 Magnesium to Calcium is 1 to 2 Sulfur at 1-2% of total solution

What is the good ratio of sulfur to the other elements?

What is in Snow Storm Ultra that provides for extra resin production?

If it's not light burn, your mix could have a chunk of chicken manure pressed up against a cluster of roots.

Yeah, I'm gonna give it Dyna a go again but none of the grow shops carry it! The Hydroplex was interesting to me in that it's claiming to deliver a myriad of amino acids that the plant can metabolize. Here's a link that describes the Casparian strip within the root and it's role in...

I had a moment when I picked up Ram Dass 'Be Here Now'. The format was unusual for the day and really planted a seed. It was quite fascinating to look at and felt to work on many levels. You gotta admire someone who creates their life actively, with intentional desire. As for LSD being...

Thanks homebrewer, I been reading up on some of your grows and they are great threads of solid info, props. I'm working to understand ratio's better perhaps an example would help. I'm in a recirculating hydro set-up with a 15gal rez using AACT's brewed at 48hrs @ 72 degs. My tap is at pH 7...

Are you saying that the plant causes a pH rise in the root zone is for the purpose of making more of the elements that it needs accessible? In other words, if you were in a recirculating hydro setup, you would allow the pH to drift within a range. Have you personally tested if this is more...

They are called variac's. In principle, it's the same thing that a model train set uses. You want to vary the voltage to control motor speed not resist the current (which would cause motor hum).

If you end up burying it, don't use metal. I'm not sure if metal detectors can detect that silver stripe on the cash though. If I was gonna bury it, I do something like a water cistern or a septic system with a fake top filled with water or poo. But honestly, the best stash places are one's that...

PEX is great stuff. You can go two routes with it. One is if the local HD has PEX (other than for radiant floor). In my area they've gone with a type of fitting that is a push fit compression. Very pricey. The other route is through a plumbing supply house which has Wirsbo which is a brand of...

collective gardner, that's an awesome grow you have happening, it's exciting! btw, what kind of ballasts and bulbs do you run and what was your thinking around it?

With the base nutes being 200 ppm per ml per gal of water, can I use the ratio's of NPK to determine the ppm's of each? If not, how would I? Isn't the 20-20-20 just 20x the concentration of 1-1-1?

Looks cool, but I think having a spreadsheet is better. You want to pinpoint trends and observe cause and effect. Having data that you can scan over a time period to compare and contrast is helpful. To answer your question, having a record of how much pH down and up per res size is useful.

That's where I would start, mag def.
