Yes a dry pH probe is trash-worthy. Let me look up some info and find a couple pictures and get back to you.

DOER said [Strips are fine when things are fine. But, when it goes to hell, probes and meters are your only tools in Hydro. The pH can bang on material rotting in the roots, in the pipes. The spot for pH spot checks can be fine while the pump bucket has gone sideways with a clog. And if the...

pH Testing A little background on it. pH is the function of hydrogen. A gaseous element. A mathematical logarithm. Little p, big H; pH. The number one interference for a proper pH result is temperature. That is why all pH readings are combined and recorded with temperature measurements. The...

Al of these would happen if you repeatedly made this mistake, however, it sounds as if you learned from it and will be much more careful in the future. I agree with the other posters that the soil buffers the pH, and your plants will probably be just fine. Keep your grow space cool, and keep...

Unless I am mistaken, the point of brewing tea is to add a population of bacteria to the soil. And bacteria have a narrow range of pH that they thrive in. They need oxygen to survive and keep them in an aerobic state. Aeration will also carry away the 'off-gassing' they do in their short lives...

AMEN brother! You are crackin me up. PS Cook some fish, get an Ona, and seal them up with plastic for ten minutes. Inspectors know mj when they smell it. Don't mean to make u paranoid, but u should be a little about officials!

Do you have a carbon filter? Could you vent a portable ac out the window if the grow room air was filtered? I have the same exact issue. Not much foot traffic, but the landscapers are out there periodically trimming. There is a great thread about DIY carbon filter in General...

with Clonex gel (Indole butyric acid, B1 thiamine): This stuff is a P-I-T-A. A few drops in a tiny glass (small damper glasses available at Sally Beauty), and a makeup brush. Prep the cutting by shaving off the lower leaves, and if necessary, scraping the skin. Paint the purple stuff on there...

I found the cups at Staples yesterday. They are not exactly like the picture, but close enough. In fact the small one is even smaller, so more carbon can fit in the bottom of the large cup. Cool. I'll try to get pics when I finally set it up. PS Found the cups at Amazon also.

Exactly. Municipalities do all sorts of stuff. Drinking water (and wastewater) treatment cant turn on a dime. Sh*t happens all the time. Aerating is the bomb.

No Worries CM. Its the solids (calcium and such) in your water. That's why filtration is so important.

When my air stones are not aerating a solution, I place them in a cut off 1 gallon water jug (1/2 full). Add 2-3 tablespoons of hydrogen peroxide on occasion. That keeps them clean. The bacteria build up on them anyway. Don't worry about it. They die and slough off. When air flow is seriously...

Cats eat grass. You're a gardener...plant some cat grass! The poor thing is probably brain damaged from the fart gas. Seriously, Cat grass and catnip plants make for a happily stoned feline.

As long as you monitor the levels in your feed water. Problem is that municipalities are not required to deliver water that has consistent Cl levels. It fluctuates based on treatment methods, how far you are from the chlorinating facility (not likely to be at the treatment plant, but all over...

Go to the website for your water provider. Dig around and find the water quality information. It is public information. If it isn't on the website, call them and ask them where to find it. The info they provide will give you chlorine, metals, solids, E.coli or Fecal Coliform. OR make ice with...

I just bought a portable AC for 400+ bucks. I should've looked here first. What was I thinking!!

I was trying to post a few pictures but it will not allow me to. :!: in pink, then "403 Error event" message. What does it mean? And what do I do now? Thanks

How much acid you add to bring pH down is proportional. If it takes 3T then it takes 3T. It is what it is. I've felt the same way about that a time or two, but it works out in the end. Nutrient addition usually brings the pH down all by itself, then the pH is usually buffered by the soil. It is...

https://www.rollitup.org/general-marijuana-growing/294579-water-most-essential-compound.html Awesome read. Rain water is great unless you have a lot of air pollution in your city. Wouldn't recommend it for LA, Houston, or the like. Are you in the southwest? I am and we have super hard water...

My pleasure. I hope this is one of many more to come. Thanks Unfortunately, I was unaware that there was a 72 hr time limit on editing posts. I am going to turn this into a journal so that I can edit it whenever I need to. Sorry about that, peeps. I really wanted to add pictures, and more...
