I have been battling root aphids in my indoor garden for several weeks. The other products I have been using were having a very limited effect, so I finally tried a root drench at about 10 ml per gallon, and noticed an immediate and drastic reduction in the population of aphids. If you are looking for a good (organic) knock-down agent to control bugs in your garden, I highly recommend this product.
I order quite often and all is well however they do not list on there web site when things are back ordered. You don't find out until you go to track your order. If it's something you must have now to cure a problem I would call to check if it's in stock.
Quickly made haste of some aphids on my cannabis plants, along with a botanigard root drench as well. Use with 5ml of thermx70 per gallon and spray in the very early morning, at least 3 hours before sunlight hits your plants.
