Review: Reduces buildup of nutrients and minerals from hard water. - I grow most of our veggies indoors and some of my plants are 2-4 years old. Since I use plant food for every feeding and we have well water, over time, there is a buildup of salts and nutrients in the soil. Although I do periodically flush the soil in the potted plants, this task becomes more difficult in plants that are are 10-15 gallon pots. I started using FloraKleen a couple of months ago in my potted plants, and it seems to be helping a lot. I am not seeing the mineral buildup on pots when I pot up plants, and my plants seem much happier - especially the older ones. I water the plants using 5 cc's of the FloraKleen per gallon of water, and water until water drains into the trays. Then I syphon off the drainage water. I am using this FloraKleen once a month, and my plants seem much happier and are flourishing. This really does seem to help remove the salts from softened water and the excess minerals created by plant foods. So far, I would recommend this product for periodic use on potted plants, especially older ones. If my opinion changes, I will update this review. I hope this review was helpful for you.

## Questions & Answers

**Q: How many days is adequate to flush hydroponics system?  1 week?  2-3 days?**
A: We recommend flushing your system from 5-7 days.

**Q: Just used this as directed. my run of is reading between 2.3-3.4 ec. do i leave it? run more water through? resume as normal?**
A: If you are doing an in-between feeding cleanse, I would just resume normal routine. pH will be very sensitive, keep close track for a few days. 

If this is an end-cleanse, run more DISTILLED/RO water through. Distilled is fine - it is 0 ppm. RO also removes carbon products like single-celled organisms and drugs dissolved in the tap water that might not show up on EC. You might also consider GH dechlorinator if this is your final cleanse and supplementing carbon dioxide during daylight hours. It just depends how much you want to geek out on it.

**Q: How many gallons of water mixed with floraklenn to be used for flushing poting soil(2 gallon pot, your supposed to flush with 4-6 gallon of water)?**
A: Ok it's 1-2 tsp per gallon. use it once 7 days before harvest to encourage ripening and clean out the nutrient build up inside the plants helps plant purge excess nutrients and also get nutrients to escape. Than the rest of the days use pH balanced water...

**Q: i have an old 1 gallon jug of flora kleen that is around 6 years old with the plastic can still on . Is it old ? Can it still be used ?**
A: There is nothing organic. It should still be good after a vigorous shake.
