Review: Arrived well-sealed, orchid treatment - I bought this for my sickly orchid, who has some root rot and some fungal infection that bud blasted her last time she flowered, thanks to my beginner level care. I did what any orchid owner would do and learned about what I could do. Copper fungicides in my house? Not a fan, one day I might be more open-minded. So I went with Physan-20. I found the product sealed really well, although you could smell it from outside of the bottle. It's potent, that's for sure. The only issue is if you're like little old me and just have one orchid, you will have to do some math to dilute down. Physan 20 has a website that helps, but I was between two doses for the two issues so I averaged it so I could mix it in a discarded drink container we would never be using to drink from again. Seriously, don't mix this chemical with food containers. It smells strong, it's probably safe, but do you want to really be a case study and/or explain how you poisoned yourself? I didn't think so. I used gloves for the whole process. I soaked the plant's roots in Physan-20 and water as it said my goodness: some gross stuff came off in the water, it was a soupy grey nasty mess (don't freak out and stop treatment if you see this, let that baby soak!). By the time the 20 minutes was up, I drained it and looked at the roots. We only lost a couple of roots, but the Physan really made it easy, made the roots clean and easy to see, I also rinsed the roots to remove any moss. It was easy to drench the substrate and repot my orchid, and even though it's been 24 hours, I'd say she's feeling better already. If she kicks this disease or it just stays under control, she may be a VIP resident of the sick bay for life. Either way, if you're buying this for at-home use, be certain your measurements are precise. My only wish is that it worked on all my plants, not just some of them. If you're trying to save an orchid, please do. They are too often discarded when they can be healed.
Review: Great product, but caution -- this stuff is serious business! - Physan 20 is a odorless, and colorless liquid. It is a powerful cleaner and disinfectant when used properly. The manufacturer recommends you only use 1ml for every 10 gallons, and THEY ARE SERIOUS! Using too much Physan 20 can be toxic and deadly for any plants or fishes living in your pond, aquarium or reservoir. And if you let it sit on you skin, it can cause burns and rashes. DO NOT MiX THIS PRODUCT WITH BLEACH OR AMMONIA. I've used Physan 20 twice so far to clean my hydroponic reservoir, and each time it leaves the reservoir extremely clean and the water "crystal clear". But you have to be very careful when using this product -- before introducing water to your plants you must wait 48 - 72 hours for the chemicals in Physan 20 to decay. Once the chemicals decay, Physan 20 turns into nitrogen, which is a major nutrient for plant growth. I love Physan 20, its a great fungicide, pesticide and sterilizer. This industrial strength product cleans what bleach leaves behind, and i highly recommend it. Thanks, C. Cole PhD

## Questions & Answers

**Q: How would you measure this?  I only have one plant that I would need to use it for right now.  I wanted to soak bark in it for one normal sized Phal plant.  1 ml per 10 gallons of water?  I wouldn't use anywhere near 10 gallons! So how am I supposed to measure THAT?  Maybe it's way too concentrated to attempt using.**
A: An easy way to measure out 1 ml/10 gal or 1/10 (.1) ml/gal is to use an eye dropper. Using water, find out how many drops are in 1 ml. Then divide by 10.But if I may ask, why are you using Physan 20 (P20) on your plant? Plant roots do not like P20. I have tried P20 in a hydroponic system and the evidence was very clear, the roots don't like it. If you have Pythian or some other fungus, Actinovate Fungicide works great. It is a bit pricey but worth it. For algae use an algaecide.

**Q: Can this be used to sanitize ro water purifiers?  seems to have the same ingredients as the sani-system sachets.**
A: I am not sure I use it in my outside fountain to keep it clear.

**Q: Does Physan need to be kept cool? Mine was accidentally left out in the hot sun for a few days. I’m hoping it hasn’t lost its disinfecting power.**
A: I have left my bottle out in the Arizona temperature and it never seems to have effected the product.

**Q: Is Physan 20 the same thing as Physan 20 Fungicide? As a first time buyer of Physan 20, I'm a bit confused the various sellers naming inconsistencies.**
A: Yes, Physan 20 is a fungicide.  I use it to prevent algae.  I suppose some sellers are just more descriptive with their titles than others.  However, they are the same.
