JohnGalt Posted March 16, 2015 Posted March 16, 2015 Hi Everybody, I am really great full for the opportunity to learn from this community. According to recent studies, the formula below could help the vase life of flowers.Unfortunately, I do not have the education necessary to create a solution base on this formula. I was hoping somebody could help me by guiding me in the creation of the solution or telling me where I can learn how to do it. Thank You for any help you can provide me.sucrose (4%) + Al2(SO4)3 (100 ppm)sucrose (4%) + Ca(NO3)2 (1%)
studiot Posted March 16, 2015 Posted March 16, 2015 (edited) Sucrose is ordinary white sugar, so no problem there. Both Aluminium suphate and calcium nitrate include what is known as 'water of crystallisation', when in crystal form. The aluminium sulphate has 18 molecules of water per molecule of supphate and the calcium nitrate 4 molecules per molecule of nitrate. The weight of this water (if present) must be taken into consideration when weighing out for solution. The good news is that both are highly soluble (not too many calcium compounds are) and non toxic. Calcium nitrate occurs naturally in soil and is also manufactured for use in fertiliser, Aluminium sulphate is used as a scavenger to 'clarify' water another form - alum can also be used. So the first and most important question is for you to find out what form your salts are in. Are they without the water of crystallisation (the called the anhydride form) or Are they crystalline?

JohnGalt Posted March 16, 2015 Author Posted March 16, 2015 Thank you very much for your answer. At the moment, I did not purchase the salts due to my lack of understanding of the process. Assuming I am trying to produce this solution at the lowest possible cost (without losing is effect) could you advise me? Regarding the weight of the water, I assume I will have to treat my water to reach some kind of neutral level and then mix the formula? Again, thank you very much for your help.
studiot Posted March 16, 2015 Posted March 16, 2015 Chemically, solutions are best fresh and not stored for long periods. But fresh is a relative term, which depends upon the stabiltiy of the compunds in solution and their reaction with things light light. I do not think you have any such problems here. So I would suggest you could easily mix up a week's worth at a time. Mixing is not difficult, just churn the powders in, to the cold water.Heat should be unnecessary. The only safety issues would be to avoid breathing dust (face mask if powder is fine). I do not know the quantities involved, or the source of your water. Neutralisation is an interesting point. Natural aquifer water may be slightly alkaline or acid depending upon the source rocks, but soilwater is usually acid. I understand from horticulturalists that flowers like more acid water than vegetables, as plants, but know nothing of cut flowers' requirements. Suspended organic material may grow in the sugar solution.
JohnGalt Posted March 16, 2015 Author Posted March 16, 2015 Thank you for your answers. I tried to find the name of the following substance on google but it did not work. Pleases could you help me to identify the following. 8-HQC (200 ppm)0.5 mM AOA + 4% sucrose,400 ppm HQ200 ppm 8-HQS
