    There are definitely benefits in growing in peat moss over coco coir (dry bud weight of 8.56g per plant in Peat vs 3.84g in Coir). I am wondering if my lime is being weird and is actually a hydrated dolomitic lime, I am going to read into balancing ph a bit more...

    The issue is that I ran water through it twice, the third time it plummeted. This is the 3rd or 4th time this has happened when I am testing and I would change out the media to fix it, but it could be due to salt buildup. I would get the mix perfect, transplant a seedling, water it. Then by next...

    I am thinking of swapping the medium to Coco Coir + Dolomite + Gypsum to keep the Ph stable in the 5.5-6.5 range. Same nutes to water with. I might even scrap the dolomite as it won't be needed to neutralize any pH over time and I am supplementing my water with Cal Mag, the gypsum should break...

    My pH is still creeping down to 5. Watering every 3-4 days when the mix is dry. Water in us 6.5ec. I also found while watering the first but if runoff is around 1.3 but then if I go over 25% runoff it starts climbing up. Is this a sign of overwatering in terms of volume, or not flushing the ions...

    Yeah I am waiting until the soil dries fully but it's still reading 1.5 from feeding 1.3. I am getting 15-25% runoff each watering. I think I will try waiting an extra day between waterings

    I have an issue with my mix. It is way too acid in the low 5s, not matter what I water with the runoff is acidic (even 8.5ph)

    Yeah I made sure to do my research first. And I do not have the storage space for the quantities of stuff you have to mix yourself. I had to buy 19kg of lime and I have used 10g, I use 1g of fertiliser per 2L of water and I had to get 2kg. I prefer the watered down Cal-mag stuff tbh cause you...

    Thanks for the reply, yeah I was getting confused cause I was sure his video method was not for recirculation. What do you think about using that sensi cal-mag extra stuff? I can drop the spec sheet in here if you like. My thoughts were it is basically premixed so I can get those micro nutes my...

    This is designed for water thats under a pH of 7.5, my water is basic at 8.5 but has a low ec. I am basically making a home brewed system of this using 20-10-20 for my major nutes and a predone mix for the cal mag fe and 20 amino acids

    I am not doing hydro, I am doing soil-less. There is no recirculation, it is hand watering. I am not using botanicare Cal-mag plus I am using Advanced nutrients Sensi Cal-Mag Xtra which already has the micronutrients in it. This is all for super small bonsai grows in Ikea ekets, not a massive...

    I am planning on adding Cal-mag + micros to my water up to 0.4ec then raise that to 1.3 with my fert. This way it is equivalent to hard tap water. Also by adding this I am diluting the acidic fertiliser I am using which will raise the pH to around 6.2 by my math, with the soil being at 5.5 this...

    Limestone increases soil pH and stabilizes it. That's why it is used on lawns. As for soft water nutrients I will probably add some micronutrients to my water however as I already have 2kg of 20-10-20 that is what I am going to use. If it was just calcium and magnesium that was missing I would...

    I dont have any limestone to add so that is my mixture of 50 peat, 50 vermiculite, and some gypsum (Mixture pH is 4.5 rn). Canadian tire is not doing any inperson orders and you cant order it from them online. I am trying to get some from other stores. It does not climb over time. My tapwater...

    I just got my fertilizer today (yay) and when I add it to my water to 1.3ec the pH is around a 5-5.5 (down from 8), is that normal for running 20-10-20. When I run this though my mixture without dolomitic limestone it is coming out as a 4-4.9

    My method for measuring is wack. I pour in tap water, collect the runoff, coffee filter, add colour pH test shake and look. The pH of my water drops from an 8.5 to an 8 when it's sat for a few hours so something that's in it is breaking down. There is no new air getting in so it isn't co2

    Dr. Bruce Bugbee method: NASA technique on Mars etc.

    The dolomite is meant to raise that. Some that you buy is designed to be slow release. I'm assuming bugbee premakes his mix or he uses fine powder that quickly changes the pH. Without dolomite the peat mix is 4.5 with it it's meant to be 5.5. personally my water from the tap is 8, but when I...

    How much water go you guys use? If you have a 1L pot thats bone dry do you add 1L of water?

    Heck I would pay you to send 20g of dol and 5 of gyp lettermail at this point if you were in canada . White powder in an envelope might look a little sketchy tho, and I need it faster than USPS can handle

    That would be awesome, that's the hardest thing to find in Canada by far. The others like gypsum and dolomitic lime are just inconveniences cause you have to buy a massive bag of each, smallest bag I have seen is 2kg at Rona which is a 2h walk from me and they are currently oos
