I may just go ahead and make up another 75 bottles, which&#8217;d give me enough for 150 biology kits. The solution is completely stable, so shelf life isn&#8217;t an issue. As with many of the solutions in our kits, we add 1 mL\/L of 10% thymol solution as a preservative. Thymol at 100 mg\/L inhibits growth of molds and bacteria.<br \/>\n<\/span><\/p>\n<p><span style=\"font-family: Arial;\">I also discovered that the Vita Grow Part C powder (pure monopotassium phosphate) had doubled in price since I ordered it less than a year ago, from $18 for four pounds to $36. That means that for about the same cost, I can just make up the fertilizer A concentrate from reagent grade phosphoric acid and potassium hydroxide. It&#8217;s also quicker. I can just dilute 149.3 mL of concentrated phosphoric acid to about 3.5 L, dissolve 224.3 g of potassium hydroxide in that dilute acid solution, make it up to 4 L, and the solution is complete.<br \/>\n<\/span><\/p>\n<hr style=\"width: 65%; height: 3px; font-family: Arial;\" \/>\n","protected":false},"excerpt":{"rendered":"<p>08:20 &#8211; It&#8217;s spitting snow as I write this.
