The one you use from start to finish what does it look like? And you can use it in soil right?
@Borderryan22 @Bluntsmoke @ThatsNotMineOfficer any one have a photo of the jacks 321 start to finish formula I can see so I know what to get.
never used it
The parts A and B and epsom salt is posted above. Those are the 25lb bags which would last 10 years for a lot of home growers. They have the 2lb part A bags on Amazon but can’t find any part B there anymore. Here is a 1lb kit. Part A is on the left. Part B is top right.
Jack’s 321 Hydroponic Nutrients Fertilizer Plant Food - 2 lb Kit
I purchased this kit myself.
You can get many different size kits on eBay, but they won’t look like the bags pictured above with the name. They have the NPK ratios on them though. Part A is more powdery like laundry detergent. Part B is little tiny granules. The epsom salt is, epsom salt.
I purchased this yesterday in preparation
I use it in coco and soil grows indoors and outdoors. Works on everything I grow. I even pump it through soaker hoses into veggie garden in summer
Okay awesome thanks everyone!
You could technically buy any green house grade calcium nitrate and magnesium sulfate. From jacks you want the part A or formerly known as Jacks professional hydroponic blend.
