flushing

Flushing your plants is more than just watering them- it’s a simple but important process that will help ensure the safety and taste of your crop. Cannabis that wasn’t properly flushed prior to harvesting will usually be laden with residual nutrients and will have a noticeably harsh, unpleasant taste that irritates your throat.

When growing marijuana for medicinal use, appropriately flushing the crops becomes critical due to the fact that a tainted product can cause further health issues when smoked or orally ingested. Depending on what types of nutrients were used to feed the crops during their lifespan, a plant that hasn’t been flushed prior to harvest can retain residual metals and salts left behind from fertilizers, thus further complicating health conditions in some patients.

Even if you’re not cultivating your own product, there is a simple way to check if the marijuana that you purchased was properly flushed before harvest. Simply twist up a joint or load your favorite implement of choice and light up! If the combusted herbs turn to a white-gray ash and the smoke has a pleasant taste without irritating your throat, then chances are the product was flushed correctly. But if the ash is dark, hard to light and / or tastes bad, it probably wasn’t flushed well or at all. You’ve probably experienced product that hasn’t been through the clean-water-wringer and wondered why you were choking unnecessarily while toking out on what appeared to be “da kind”.

For those of you that don’t partake in the toking-of-the-trees and prefer to orally ingest your marijuana, the only way to ensure your buds were flushed would be to have your product professionally tested in a laboratory, or even better would be to grow it yourself and flush!

Flushing is a simple process at the very end of the flowering cycle. If you’re growing hydroponically, run clean water with no or very low (< 200 ppm) nutrients in your reservoir for the last week prior to cutting down the plants. For soil-grown plants, stop nutrient feeding entirely in the last 7 to 10 days and water each plant with twice as much water as the pot size will hold. For example, if you’re using 5-gallon pots, give each plant 10 gallons of plain water to flush residual salts and fertilizer from the soil.

This simple step before harvest will help ensure the tastiest, safest buds for your enjoyment!
