Guys, After the spring and early summer rounds of squirts, I have already grown tired of 'mixing on the fly' with my small backpack operation. What a pain, and does not look all that professional either. I would like to take 1/2 step up, and purchase some 4 -5 gallon poly mixing jugs in which I will premix 3-way+sticker (or other chems as needed) at home - therefore enabling me to simply pour into my backpack on the job. This would be a good time and energy saver for now, until I assess if I want to step up to a skid/ride-on for next season. Where can I purchase these types of jugs? Would preferrably like to do online with someone reputable. Thanks!
