The Jack’s nutrient line made feeding easier due to its simplicity. With fewer products to mix, it was quick to prepare, and the scoopable measurements were far more convenient than syringes. This streamlined the process and made feeding more manageable, especially during the recovery phase. However, I can’t fully assess the impact of Jack’s nutrients on plant health, as I switched to them when the plant was already stressed. While they didn’t seem to improve things drastically, the plant didn’t suffer from them either, so they appear to be effective without being harmful.

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!

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.

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.

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.
