  • Big Boost for my Vegetables

  • Almost perfect!
Size: 16 oz Bottles (2 Pack)
Great product and very reasonable price on the twin pack. The items came shipped in an outer and inner envelope. The reason for the 4 out of 5 is because it arrived with some leakage. Now to the their credit, they did use the "gripper" adhesive on the both the bottle caps in addition to double packing the items. But the gripper adhesive sticker strip is meant to be applied not only to the bottle cap, but also a portion of the bottle to prevent the cap from working itself loose. If the process can be improved to make sure the "gripper" is attached to both the cap and bottle, I'm sure the leakage issue would be significantly improved or eliminated. On the up side, the double packing with the inner package being a plastic envelope allowed me to salvage the 1 to 2 teaspoon of fertilizer that leaked. Coo-does for taking that extra step that others simply skip. Will be back again as soon as I finish using these. Thank you for the excellent value! ... show more

  • I'll always recommend FoxFarm!
Size: 16 oz Bottle (1 Pack)
I love being able to purchase this individually. Good shipping, no leaks or delivery issues, it was packaged well and came in a timely matter. My plants thank me and after just a week of use, you can tell the difference. I live on the Canadian border and only get a few months of outdoor gardening, so this really helps my plants get that extra boost they need to have 2-3 harvests before the frost comes. During the winter I move all my pepper plants, herbs and any potted flowers inside and keep them under a grow light to continue to have fresh produce in the cold months, and FoxFarm nutrients keep my garden happy and thriving, even when there's no natural sun and artificial heat. I would highly recommend over other nutrients out there! Their measuring chart is easy to understand and use so you never overfeed your plants. ... show more

  • Great Product
Size: 16 oz Bottle (1 Pack)
Been using this product since my tomato plants started to bloom. Have almost too much fruit. I have been applying at 50% strength and it still works great. Been applying directly to the roots and main stem.
