Review: FANTASTIC - SAVED my water propagations-- they finally stopped rotting!!
Review: Perfect fungicide for my indoor garden project. - This product works great in my recirculating deep water culture screen of green garden setup. Applied at a rate of 1ml per 20 gallons of nutrient solution, it makes for a great companion and backup to my chiller to effectively help prevent mold, mildew and other rootzone and nutrient solution problems. This product is very affordable compared to products such as hydroguard and it's much more concentrated.

## Questions & Answers

**Q: On a scale of one to hoo Nelly, how bad does this stuff smell?**
A: Hoo nelly! It is pretty bad. It is also against vampires because it is very very very garlicky!  
You and your garden will smell like a 500 year old Italian trattoria but it works like a charm. Kill various pests and fungi.  The smell is unnoticeable after a couple of days and I would recommend it regardless.

**Q: Could it be used for hydroponic strawberries? If so, foliar or root or both?**
A: Yes it can be used hydroponically 1.5-2mL/G at 2mL/G it is about it is still 6 times strong then Hydroguard I have used it for years on hydroponic pepper plants and have not had any root issues yet it can turn the roots a very lite tan color do not confuse it for rot roots will stay thick and clean to the touch I talked with a AG rep that recommended 2mL/G for hydroponic its cheap and last Hydroguard works but it will come out like 10 times the cost save the whales

**Q: can it be used as a soil drench?**
A: Yes it can. Its about 4ml per gallon of water.

**Q: This product work for Fungus Gnats?**
A: Mosquito bits works on fungus gnats
