J.R. Peters, Inc.

Been using Jacks for almost a year. Almost from the the first few weeks, I knew I found what worked well for my tap water and environment. Finally got results I have been expecting, won't use any other base!

All I use start to finish

Love jacks

I'm not 100% sure what to think of Jack's yet, but deep down I still feel like it's better than liquid nutes and not knowing the macro/micro splits.

Ol' Reliable

I just started using Jacks RO on this grow and I was impressed with the stability and the cleanliness of the solution. It worked very well in my autopots. The one part mixed up very clean and was very pH stable. The results speak for themselves.

Jacks FTW

Excellent nutrient ,I use it start to finish and have for over 4 years

Ol' reliable.

Using these dry nutrients makes storing easier. I like that they're designed to be used with tap water. Combining with Epsom salt was easy. Dissolving was annoying and getting the EC right a bit of a process. Results seemed good, though. The company seems responsive and to care about the customer.

Love this stuff, love long fan boy!

It is the simplest and most cost effective way to run hydro. Easy peezy. I been on jacks for years now.
