Pumice....A great inexpensive find for many I hope!
Comments (18)Hey, What's up with your town anyway Pug? I have a whole bag of that Napa stuff on my porch, and I have yet to try it...It definately has a nice color..I think I remember jsutaguy saying at one time he likes it alot. If he did,then it is definately good stuff and a great substitute for turface as penfold2 says. That is why I some a while back, I was too lazy to drive 15 miles to get turface, when the Napa store up the street had Floor Dry. Was it justaguy who said he liked it? Someone did, and was having great success with it. They also said it looks nicer in a soiless mix.. . It's funny how some areas make it so difficult to find this stuff, and yet places like my area, I can buy all 3 products within a 20 mile radius..Sorry you can't get the stuff so easy..:-( By the way, I have never seen the barbecue lava mentioned. Maybe someone will hep you on that one...Sorry... Are you sure that NO one in your area sells anything like turface, pumice, or Floor Dry? I hope you find something. Penfold2, thanks for the link. There is definately a vast difference between both product for such close wording..:-)...See Moreperlite vs pumice ? your preference?
Comments (47)As I understand it the point of using porous materials is not to increase/decrease water retention on the outside of the particles, but to provide sufficiently large pores to allow air circulation around the roots while still providing enough humidity (from water stored in the inner pores) to help the fine roots to stay alive. That's the point of using products like Turface or Floor Dry. I'm just wondering if pumice is really in the same category. If you look at xerophyte nyc's experiment here, you'll see that a similar substrate, lava rock, holds very little water. (Thank you for that, xero!) The pores in volcanic rock may be so poor at storing water as to make these substrates comparable to granite, a substrate used for its minimal water retention....See MoreRed Lava instead of Pumice?
Comments (18)A long time ago I read about lava rock having a high fluoride content. I now found this info at simplyhydro.com: -- Lava rock has successfully been used used in hydroponics for many years...but less so now, due to other alternatives which do not have sharp edges that cause damage to the roots. Also due to chemically treated lava being hard to find in many areas of the country. -- (This makes me want to it use much less than I have before...) I have crunched up lava with a sledge hammer but found it tedious. It does make contrasting topping for bright succulents. Re: "no peat" mix. I read about peat being acid and consequently inhibiting fungus. I also read about most cacti and succ.s not being too particular about the ph of the soil. So I grew some smaller echeveria types and a couple of others in pure peat, with a wick in water, like African violets. Some are going on 4 years now. I've been amazed. Lost a couple - likely because that peat had some soil, too, which provided a fungus foothold. I followed up on "chicken (granite) grit" from another blog. Yup, the local farm supply had it. Cool stuff. The Rockies in a bag. Heavy, but a lot of people recommend it: 1 part grit, 1 puffy stuff, 1 fine peat....See MoreFinding crushed Granite/ 6/20 sand small lava rock or pumice i
Comments (7)Tom I was checking my email throughout the day and I didn't know if you got my email address. I am already back from Largo, and I was at Haines City before that. I was hoping to have gotten your phone# while I was up there so I could have stopped by. I bought 8 bags of the 6/14 silica sand so at least I have something, but I still would prefer the Gran-I-Grit. Tom, how long is the wait once you order it from that feed store? Is the product actually Gran-I-Grit, or some different named stuff, and is it similar in size and structure? I still might take you up on the offer for the grit when I stop back up that way. We need to exchange emails again if you nerver got my email....See Morebikerdoc5968 Z6 SE MI
