Florists for years have been manipulating orchid flower colours by adding food dyes to their watering. Could the same technique be used to alter the bud colour? Has anyone tried it? I think this would be an interesting experiment with little or no downside…

If it was clear customers wouldn’t trust or buy it. You have to be able to see it…Nutes would look like water otherwise. Buy dry powders instead…and you save money by not paying for water.

The last thing I want is any di…

@Shatter I agree. Just started using MaxiBloom, but it is a bit more challenging to get the powders to dissolve properly and maintain the pH like GH Flora trio does. I practically never had to pH adjust.

I have to monitor my pH every couple days, and PPM, more as the salts build up before flushing, it’s a pain in the ass but well worth it knowing the Ionic bonds and their characteristics over time, with liquids you never know how many atoms have bonded and precipitated unless you get your mix straig…

Dry powders are pretty stable. Shelf life on most dry powders in nutes are >2-5yrs. I’m in DWC so no buildup.
