These products are amazing. They are easy to use, come with their own spoons for correct measuring size, and add and immense increase in flower yield ability. Follow the instructions to a T, and do not ever use over. This stuff is potent. There is no other product out there that creates the yield this does. I also use this with 3 other Fox Farm Products, Grow Big, Big Bloom and Tiger Bloom for maximum growth. I will never use any other products after using these!used these nutes the last six weeks of my grow and this was the best meds I ever grew. These will be used in the future. 100 percent fan of fox farm.The results of my harvest were impressiveGood stuff I’ll definitely use againLove itThe product is wonderful, the problem is being disappointed with seals removed and product missing. No one seems to be doing quality control. Very disappointed, I put my trust when I buy.It helped my plants produce even bigger and better, more beautiful and sticky, very fragrant flowers. There were new hues in the flowers, like purples and reds.Order arrived overnight, which was a nice surprise given original estimate of delivery. All 4 auto's are finishing up on week 5, so I was looking for a soluble solution that's easy to use to fatten up pre-flower to flower. Applied at last night's scheduled watering following directions provided (i.e. on bottle and FF website). Woke this morning to find pre-flowers exploding. So, open sesame looks to be a game changer for me in setting up for bud density and quality. Looking forward to using the next two all the way up until harvest. Full discloser, used in concert with FF Happy Frog soils and dry solubles, again according to feeding schedule adjusted for auto's short growing period.
