Message: I have done the low water immersion technique several times from your website, and was just wondering if the dyes should be dissolved in warm water or whether it matters?

It does matter, but in two opposite ways. Reactive dyes will be destroyed before use if you dissolve them in hot water, and last longest if kept in cool water, but dyes dissolve more easily in warm water than cool water. I use room temperature water (70 to 80°F or 21 to 27°C), myself. 

Once I dissolved fuchsia in hot water and added it in LWI to some blue dye I'd dissolved in cooler water, expecting to get purple. What I ended up with was just blue. The hot water killed the reactivity of the fuchsia - it all reacted with the water before it could react with the fabric.
