Terrible Experience with Digital PH Meters
Comments (4)Finding myself in a somewhat similar scenario, my solution was to use pH strips (paper). It's not as accurate, but a whole spool of tape costs less than the shipping on even the lightest pH meter ($5)! I've never had any pH problems and the tape has always been accurate enough for me. I buy my tape from Enzymedica and it comes in a plastic container with the comparison chart right on the side of the spool. I keep it inside my greenhouse and it never "goes bad"....See MoreSmart Irrigation Controller
Comments (13)That's what I do now, but it's a PITA. I'm forever adjusting the run times, turning it off, turning it on. My controller at the old house at least allowed me to specify a number of rain delay days and to make percentage seasonal adjustments. The current one requires a step ladder, a flashlight and a lot of button tapping for the same activity. By the time it rains again, the battery has died on the rain sensor. My real problem, though, is that when I travel in the spring and fall. rain and Santa Anas always seem to arrive while I'm gone!...See MoreMeasuring pH in soil, compost and li: Need help calibating a pH meter?
Comments (13)Yeah ... lots of critical things to consider such as initial and changing pH effects*, buffering, multivalent cations, anionic and cationic micronutrients, and zeolite like ion exchange surfaces on soil particles, which make it a play day for chemistry discussions. Then the attack and breakdown of plant and animal litter to slow release nutrients brings up neat microbiology and biochemistry aspects. Material science then decides to manipulate the situation with osmotic release and diffusion of encapsulated nutrients. And hydroponic principles try to partially play nature taking over the hydrology and lighting it up. Physics kicks ideas in there on this last aspect. For instance did you know that fluorescent light indeed glow when struck by energy (as you know), but much of the light intensity flashes through a series of distinct colors at 60 times a second? * Plants cheat neatly by manipulating ion exchange release of cationic nutrients. They knock off ammonium, potassium, magnesium, calcium and other positively charged ions by producing acid(s) to knock it off. H+ alone can cause the exchange but if the acid is on a small organic base (anion) like oxalate this organic can diffuse around and pull at the cations on soil that the plant wants and help knock it off, helping in the "weathering" breakdown of soil too. Chelators made by plants and microbes make it really interesting too. They diffuse around and hold certain critical nutrients so tightly that the plant has the choice of finding more, having a deficiency (specific nutrient starving), making a stronger chelator to take it back, and/or breaking the chelator down to free the nutrient. Now the fun parts ... the plant one might be considering is not be alone. A group of similar or different roots might be working together AND competing in that patch of soil, with different players at different depths Trees cheat and certain non woody plants cheat and go low. Moles, gophers and field mice run through this soil zone toox playing their games. No soil contact then no nutrient uptake, no root then no nutrient collection there for the plant, loss of stored nutrients and need to spend energy replacing the root. And there are smaller life forms co-inhabating the soil with the roots that are also directly or indirectly effected by soil pH. Let's put them into three classes as those that (1) don't generally effect a plant much, (2) can hurt the plant, or (3) can help the plant. Let's see ... hurting a plant is bad, unless it hurts a seriously competitive plant more. Helping a plant is good, unless it's again that serious competitor. Plants are not stand alone organisms in naturem. They live in community with microorganisms. So what if the soil pH helps support the growth of a microbe that can grow all over your plants roots? Sounds bad I know, but there are those three classes mentioned above. If your microbe is a pathogen that is bad. If it doesn't attack the plant but runs out and breaks down nearby leaf litter, great free food. It it doesn't hurt your plant but by being on root surfaces can compete with and stop pathogenic microbes from getting a foothold, great a free natural inoculation for immunity. There was a company called Eden Bioscience a couple decades ago here in the PNW that made an interesting observation. In large scale evergreen seedling production for forestry sometimes there were large scale fungal blights. Sadly alot of the seedlings all died at once in mass. However, sometimes there were a few seedlings near each other that did not succumb! In fact they looked totally healthy! When isolating bacteria, yeast and filamentous fungi from the surfaces of these plants they found that certain kinds could be grown in the lab that protected seedlings from attack, when sprayed onto them. These microbes grew best in their optimal pH range. They indeed colonized the plants, in this case leaf surfaces. And their presence did protect the leaves from pathogen attack. Obviously similar things must be happening in nature in the leaf canopy and also soil root zone of plants. So when a plant likes acidic pH 5 - 6 soil, is this just because nutrients are more available it? When I went to school, in what now seems like the dark ages, most plant physiology books focused almost solely on this. Or is it because beneficial microbes helping feed or protect the plant need that pH? My firm assumption is that both chemical and microbial pH dependent effects interact to make an optimum environment for that plant. And that some plants in the natural environment survive best, rather than grow best, at their optimal pH range. Why do many fungi sour (strongly acidify) what they are busy rotting? Niether competive microbes nor does the dieing plant tissue like it. The fungus gets more. This is exactly why you want to check the pH in the soil that you might be soon preparing for your new vegetable or herb garden this spring. Too basic, your plants starve. Too acidic, the pathogenic fungi don't starve. Then like the heirloom story of The Three Bears ... there's one pH that's just right....See MoreIs a “Smart Home” smart?
Comments (51)trashcanman, I meant cat 6 obviously. I've had this argument further up on this thread (where I did say cat 6), but you just can't convince some people that technology improves/changes. "If you have neighbors close by, you are sharing that wireless space with them, and as they add more devices, your speed and reliability will trend downward". Just to reiterate, this is a dated way of thinking... there is very little to no interference with modern 5G routers. Anecdotal proof: I am sitting in my tiny temporary city apartment where there are 28 other wifi networks available, and I can still watch perfect 4K TV through my wifi and my internet is super fast. In 10-15 years, those of you running cat 6 will have to tell stories about the old days when the internet ran through wires and devices had these strange "ethernet ports" every time a kid asks about the strange useless outlets on your walls. artemis_ma, I did run audio wire for speakers.... even though Apple is convinced that wireless sound is ready for prime time, I don't think we are quite there yet. I think we will be soon, but I am not willing to wait a few years to listen to music (also speakers in the ceiling do need power some how). I am pretty happy with Spotify for what you are describing, but that is an entirely different conversation....See Moregreenshoekitty
