Jack's Nutrients 16-4-17 Hydroponic Fertilizer for Vegetative Growth in Continuous Liquid Feed Programs, 25lbs

We used Jack's for all of our nutrient needs for our hydroponic lettuce business. Great product.

I used to buy those three part 16 oz. bottles of nutrients for all my grows, but after trying this stuff I am converted. It's a one part mixture, just add water, and my plants look great.Granted the N-P-K ratio isn't formulated for every plant at every grow stage, but its general enough to get the job done... and its so cheap... You can make 1,996 gallons (7,559 liters) of solution at 1,500 ppm with this one 25 pound bag.If you want cheap and easy, I highly recommend this product.

This fertilizer is perfectly balanced to produce the best vegetables. Your plants will outgrow the weeds and that's not an easy feat.

Easy to use, goes into (and stays) solution and the lettuce (monoa) does very well with it. Turn over a small crop operation every five weeks from seed to harvest.

This stuff is MONEY!!! I’m using it for my vertical hydro and my lettuce has never been happier!

Bought this for lettuces. I'm 6 weeks in and starting to trim the outer leaves every other day in a 2' x 8' tank. Does the job!

Dissolves quickly and completely and works well with everything we've grown so far.

Great, consistent results or growing hydroponic leafy veggies
