i decided to try a little experiment.i was trying to shock the plants with slowly releasing ice cooled water to turn the plants purple faster(gdp and purple kush)similar to a big temperature drop at night.
60 degrees for two hours a day for one week.(never measured)
i used around 8 ice cubes per 5 gallon pot during the start of a two week flush.never having to water.this way i could use ice cubes every day for a week without my soil getting water logged.
the ice cubes where used during lights on.taking about an hour to melt.(im sure using ice cubes right before lights go out would make the ice cubes last a lot longer and the soil colder longer).
it worked,the plants feed ice cooled water purpled faster.
the plants feed room temperature water purpled up a week later.
if i used ice cubes for the full two weeks i might have had more dramatic results.
having a bunch of extra ice cube trays might be ok for small grows,but large grows might be a pain.
