Review: Great fertilizer! It’s a must have! - Great fertilizer, cannabis plants love it! I had some old cannabis plants under the lights all winter long after harvesting them. I didn’t cut the entire plant down, I left some small branches and leaves. Come spring the plans were not looking very health until I started using this fish seaweed fertilizer and after a week, new growth started showing up, now I should get a second harvest out of these plants from last year. Well worth the money, highly recommended!
Review: Excellent Product! - I am very happy with this fertilizer although the fish smell is VERY strong. My tomatoes have thrived, produced abundantly, and the plants are still healthy even though we're getting close to the end of the summer growing season. You cannot go wrong unless you use too much. This is it! I will be buying more when this runs out.

### ⭐⭐⭐⭐⭐ Great fertilizer! It’s a must have!
*by G***S on July 7, 2021*

Great fertilizer, cannabis plants love it! I had some old cannabis plants under the lights all winter long after harvesting them. I didn’t cut the entire plant down, I left some small branches and leaves. Come spring the plans were not looking very health until I started using this fish seaweed fertilizer and after a week, new growth started showing up, now I should get a second harvest out of these plants from last year. Well worth the money, highly recommended!

### ⭐⭐⭐⭐⭐ Excellent Product!

I am very happy with this fertilizer although the fish smell is VERY strong. My tomatoes have thrived, produced abundantly, and the plants are still healthy even though we're getting close to the end of the summer growing season. You cannot go wrong unless you use too much. This is it! I will be buying more when this runs out.

### ⭐⭐⭐⭐⭐ Foliar Feed + Grow Bag Secret Trick for Early Tomatoes!
*by O***M on March 17, 2021*

I use this foliar feed as part of a tomato growing trick that produces tomatoes a month earlier than my old traditional growing methods. Here is what I do: I plant tomato starts in 2 or 3 gallon BLACK fabric grow bags using any potting soil with fertilizer in it. The grow bag tomatoes go into my garden cart and are wheeled around to the sunniest, brightest spots of my yard. The sun heats up the grow bags which warms the tomato roots and sparks rapid growth. I use this foliar feed (about 1 tablespoon in the Behrens 2.5 gallon galvanized watering can) and foliar feed once a week. That’s it. The tomatoes EXPLODE. They grow at an almost impossible rate that boggles the mind. Growth and production continues heavily throughout the season because they got such a strong head start. Here is an example timeline for 2021’s tomatoes: Bought hybrid and heirloom tomato starts in 4 inch pots Sat March 6. Starts were 6 inches tall or less; most 4-5 inches. Planted in grow bags, watered in and foliar fed that first day. Wednesday March 17 (took included picture of growth). Tomatoes are 12-15 inches tall, two Early Girl hybrids have multiple fully open flowers and two heirloom black cherry have flower clusters just opening. This is ELEVEN DAYS after being purchased as 4-6 inch tall starts. Several days of nearly 80 degree weather in my area of Texas is what helps make this possible (warms the black grow bags which warms the tomato roots and warm tomato roots equal fast growth) and the foliar feed gives the plants a very visible boost. If we’re going to get a cold snap, all the plants are wheeled into the garage. After risk of frost has passed, I remove them from the grow bags and plant the tomatoes in the raised garden beds, cage them and continue to foliar feed bi-weekly until tomatoes begin to ripen. (I use calcium & magnesium as needed, too.) I hope this trick helps other backyard tomato enthusiasts! P.S. I use any brand black fabric grow bag so long as it is black. 3 gallon size shown. All have come from Amazon. I like the smaller 2-3 gallon sizes because I can fit more in the garden cart which means more tomatoes!
