Where to get horticultural pumice?

lloyd: Snow or rain collected directly into a bucket in Toronto is 0 PPM TDS. From a roof, check the TDS. If < 25 good for CP's, 25->50 Ok for bogs or big outside pots. Jun 22, 2015 18:17:41 GMT -5
lloyd: pH of water with very low TDS doesn't mean much so I wouldn't bother checking. Jun 22, 2015 18:19:20 GMT -5
lloyd: Aluminum will contaminate water so you should know what your roof is made of. A TDS meter will not check for aluminum. I have an aluminum test kit which showed my dehumidifier water had toxic levels of aluminum. Jun 22, 2015 18:21:06 GMT -5
Dennis A(cook1973): why do people look for better ways to get water or a CP? for under 2 dollars I can get 1 liter of aqua-fina RO water....0ppm or for a little more I can get 4 liters of distilled water...0ppm too! Jun 23, 2015 8:42:46 GMT -5 *
lloyd: 99¢ for 4 liters distilled H2O @_Costco. Jun 23, 2015 14:08:37 GMT -5
peatmoss: I used to get mine for about a buck a gallon at a fill your own distillery. Worked pretty well, but the drive was a bit much, so I switched to just buying it at the store. Now I run a combination of water I buy at the grocery store and rainwater. Jun 23, 2015 16:00:41 GMT -5
peatmoss: The only problem with my rain barrel are the mosquito larvae that run out the tap everytime I go to get water. Fishing them out is a bit of a chore... Jun 23, 2015 16:01:22 GMT -5
hal: My rain barrel has a screen over the water inlet so 'squitos don't get in. Jun 23, 2015 16:14:39 GMT -5
lloyd: Just use a dollar store colander to sieve out the mosquito larvae, then you can feed them to your plants-kill them first (the larvae, not your plants) or you will have mosquitoes flying around your house. Jun 23, 2015 21:54:26 GMT -5
peatmoss: Ours used to have one of those. It must've rusted out, or it has enough big holes in it for the skeeters to get through. Should probably fix that... Jun 23, 2015 21:54:43 GMT -5
peatmoss: Colander is a good idea, so is free plant food. I'd bet you could feed them to fish, too. Jun 23, 2015 21:56:25 GMT -5
amanitovirosa: ...I filter my collected rainwater, seems to be working... Jun 23, 2015 21:57:57 GMT -5
willyckh: My plants arrived!!! Thanks Cole :D Jun 25, 2015 12:04:14 GMT -5
bonfield: You're welcome :) Jun 25, 2015 14:37:28 GMT -5
Dennis A(cook1973): @ Peatmoss....I have a bottle of Bloodworms with just 1 ingredient....Freeze dried mosquito larvae!! Jun 28, 2015 16:59:55 GMT -5
willyckh: I have some small aquatic snails, should I put them in my water trays to eat the algae? I'm tired of changing the green water every few days. Jun 29, 2015 17:35:54 GMT -5
lloyd: Throw in the U. gibba. Jun 30, 2015 8:22:41 GMT -5
willyckh: Alrighty then Jun 30, 2015 9:24:12 GMT -5
peatmoss: Lloyd is right, the trays where I grow my U. gibba are usually algae free. I guess it grows fast enough to outcompete the green slime for nutrients. Jun 30, 2015 13:29:03 GMT -5
willyckh: Nice! Guess I will have to divide my U. Gibba and put them in all the trays. Jun 30, 2015 14:36:40 GMT -5
