ON IT! I'm also running an experiment with 8-8-8-8-8-8-8-8-8-8-8 Macro and micro nutrient ratios. I'd actually expect there to be a lot of salt stress if I did something like that.

Alright, so what is the consensus on potassium in the flowering stage? I've been “doing my own research” on nutrient compositions of various solutions used on cannabis plants in industry and in scientific papers. After all my reading I’m starting to wonder if the hype with high potassium...

Hell yea! How are you liking Super Metroid?

A couple thoughts. 1. Water by it's self is totally shit at holding pH... period. Assuming your RO water's TDS is <25 it's not going to do a good job at maintain pH at all. Even nutrients solutions as high as 1000ppm don't do a good job at maintain pH because they don't have any buffer...

Alright, what is your EZcloner cleaning routine? Do people use just bleach/hypochlorous acid for sanitation then use something else for cleaning out the gunk out of it? Do you scrub the trays and everything when you are done? I was thinking of doing the following once I’ve transplanted my...

I mean this in the best way, but are your meters calibrated? I would hate for someone to be going down a trouble shooting path with inaccurate readings. What meters are you using? My hunch is that you might be able to get away with more aggressive pH adjustment if using phosphates or an...

Holy hell, Prodeus looks sick, I'm 100% downloading that on game pass this evening.

Serious Sam 3 - It's Croatian Doom...basically an alien shoot em' up on the biggest fucking maps you've ever seen and every weapon is some sort of noob cannon, which is necessary since your kill counts are >400/level once you get going. If you've never heard of the series, I highly recommend the...

If you want to sterilize your system you will need to add chlorine up to about 200ppm (0.02%) and let if run for like 10min to do the heavy duty killing of bacteria, then flush with regular tap water with a chlorine concentration of 4ppm. The link that HydroDan posted for how to make your own...

Those look pretty good actually! I've kept some in peat moss cubes for like 2 weeks for the fun of it and I bet they could have been transferred to a pot. good call on the vent, you should leave it open.

Oh no I'm taking about my laboratory background. I used one of these bad boys: https://www.coleparmer.com/i/thermo-scientific-dual-star-ph-ise-mv-meter-kit/5882520 And a Oakton EC...

Thank you all for the recommendations on meters! I really really appreciate it! I come from a biochem background and I'm a total gear head As much as I'd like to get some of the $2K pH meters of $800 EC/TDS/resistivity meters, my budget isn't that high!

Out of curiosity how much of the pH down where you using? I was looking at the bottle online and I can't believe how little they recommend for pH control! 1-3mL per 100L would leave you with like 0.015grams per liter - that's 0.078mM that's ~25-12.5X less CA than I've read you should use...

Citric acid is a really nice substance to use for pH control because 1 - you don't need to use a lot of it for good control 2 - its a GREAT chelator for your metals such as Iron, Manganese, Calcium, and Copper 3- its non-toxic to basically to all life on earth. If you use citric acid for pH...

This is going in my personal collection of online proverbs.

SMH...Look the thing about the microbiome is that we just barely understand what is going on even in the human gut, I mean we have an idea and there are cool study's on how the whole thing changes over a person's life time and how it affects the many different system in the body. The one thing...

Oh damn, that kit has everything! how long have you had yours?

What about the Hanna Instruments meters? I'm seeing similar pricing there, but man, some of the stuff they sell is super expensive and I'm not sure at what price point it doesn't make a difference as to what meter I purchase.

I know this may be a dump question on an almost dead thread but did you consider that the water system might be the culprit of your TDS? One time I was working in a lab where the TDS/conductivity of a buffer solution was rising over the course of a couple weeks and it turned out that someone...

Hello guys, First time posting on the forms after lurking around for a few months. I'm starting to get into aeroponics and EZcloner stuff and I'm having a hard time finding recommendations for EC / PPM monitors. What are you guys using? I'm aware that I will have to keep an eye on water...
