hey guys this is matt with for hydroponics calm and today I'm going to be talking a little bit about medium ph soil pH how to raise and lower it and one way to test for it what I'm going to be using today to test is going to be the digital soil pH pen by blue labs for my favorite devices to test a ph of soil and solution first thing we want to make sure we have a saturated medium you will not get an accurate reading if this medium is bone dry or relatively dry so first thing we're gonna do is take some filtered water I have a PhD about 6.5 and we're going to go ahead and add it in there. so so once you add your water depend on the container. make sure you had enough to get the tire medium what we're going to go ahead and. a bunch of test hole so that this meter comes with a nice pics bike back in. cases the actual meter itself so you're going to use this to punch your test holes you can see its pretty. long so you get a nice accurate reading for midway down into your container and. so first thing we'll do is just shove it down in there and it's not much. different than a bamboo stake do not be afraid to go ahead and stick it in their plants will handle this no. problem and then as you pull it out to be somewhat gentle so that the soil does not. back fill in the hole and then we're going to go ahead and take off the spike. and which shows you the actual probe itself. we're going to the probe on and then we're going to stick this broke down. into the actual test hole I'll get that down there all the way and they contact with the actual soil and. then we're going to let it do its thing and stabilize and take a couple seconds. sir so and while that's going on we're going to talk about how to move the pH of the. soil up and out so one easy way to do it is your garden live in your soil certifier so I found that this was. extremely low or lower than i wanted to be. I would just apply my garden line by top dressing which is just scratching the. surface of the medium and sprinkling it out there on the dosage amounts are. actually right on here you can do large amount of smallmouth so they have you. actually cubic foot and stuff like that so then on top of that that's a good. point 7 i'm gonna if it ends up being too high. you know we're going to go to our soil to the fire so this if you have a test. of a nine-point-oh or eight. or something and you want to bring it down. relatively quickly the soil instead of fire be this great idea for you same thing just scratching. the surface sprinkle it on there and over the course of a couple weeks that will lower your. your ph obviously want to keep monitoring it and making sure that it is. dropping and do not reply a little at a time and continue to test this is still. dropping down we're down to 57 now 56 another species of plant this you know could be good or. bad but most people are trying to stay between five and seven and make sure. you're performing all these you know test with a calibrated meter of me. obviously if you do not have to calibrate the meter your accuracy you might do the. wrong thing at line at a set of fire at the wrong time. so if you have any questions about how to see and calibrate an actual meter. we have a video on it that shows you how to do all the calibration stuff. I'm going to check that out at the moment it's seems like it stabilized. about 5.4 and once it stabilized we're going to do is not gonna stop the test. they're going to go home ahead and perform about two or three more punch. holes in this case the same container and i'm going to take an average of this. medium I'm not going to just make one test hole and say the whole thing is exactly that. medium will do a couple tests I'll take an average in my head and then we'll apply accordingly. so I hope this helps you guys out if you have a PHS years you're wondering about. how to test how to move it around the last thing I can say is that if you want. to do it without anything like this and you're just trying to bump it a little. bit up you can water in a little high or a little bit low so my ph is lower than. i wanted i might water in at 65 to 68 out for the next week or two to how to. bring it up and if i was to highlight first I might water and. 52 to 55 for a couple weeks trying to bring it down. that's the way you can move it around by just a gentle nudge with your actual. solution last thing to be test to run off of this if you add 6.5 water in and. it's coming out at 5.2 that's another indication that your medium is really. low and that that could be part of the problems that you're having on this does. test solution so you can test this and then we'll take it out and then we'll take it out and to Lester run. off right afterwards which is another reason i really like this pen so i hope. this video helped you out we have all this stuff at 400. com please come check us out and we'll see. you next time yeah
