FoxFarm Grow Big Liquid Plant Food - Bloom Fertilizer for Flowers, Fruits, and Vegetables, Perfect for Indoor & Outdoor Potted Plants, NPK 6-4-4 (2.5 Gallons)

I have not yet used Fox Farm's Grow-Big.However, it came highly recommended by an international group of seed sowing flower farmers on Facebook.Many, if not most, of the flower farmers use Grow Big weekly to promote growth in super slow growing flower seedlings, including lisianthus. The idea is to encourage strong stems and reduce soft growth, up until 6 weeks before planting them in the ground, when other elements used to promote blossom development and flower growth get added into the mix. Some flowers are such painfully slow growers that they often require months and months of higher levels of a non-urea based nitrogen. (Depending on the culture sheet, lizzies, for instance, need a 15-0-0 organic fertilizer, or a 46-0-0 urea based fertilizer, or for a constant liquid feed a 15-5-15 or a 20-10-20 NPK, with the nitrogen derived from a calcium-nitrate based formula.)It's relatively easy to locate a 15-5-15 non-organic soluble fertilizer. Jack's or Peters both offer 15-5-15 fertilizers.It more difficult to find these high NPK numbers and proportions in organic and semi-organic water soluble formulations. Grow Big (at 6-4-4) has more Nitrogen, Phosphorus, and Potassium (N-P-K) than the more widely used soluble Fish Fertilizer (typically 5-1-1) a former favorite of the members of the FB seed sowing group.If truth be told, in a course of a week, the flower farmers twice fertilize: once with Grow Big and then a second time, toward week's end with a feeding of diluted (1/2 strength) ammonium calcium nitrate (15.5-0-0), also available at amazon.Grow Big undoubtedly stimulates other types of plant growth. Just explaining how and why I purchased this particular product and why early infusions of nitrogen remain important for a flower seedlings development.

We started seedlings this year, and we thought we had everything covered. But our seedlings just never took off. Once we took them out to begin hardening, natural light did wonders for them, and they started to grow new leaves, but then they started wilting and looking sad. We realized our soil, while rated for a full month of plant food, just wasn't holding anything anymore. Cue this great little product. It literally brought our cucumbers back to life, they were loose and limp and sad. Now, they think it's time to flower, but otherwise are flourishing. All seedlings have gotten taller, thicker, less leggy, and have increased leaf production. I couldn't ask for more. 2 feedings in, and every day they get stronger. I can't recommend this highly enough.

One of the best products I've found for replenishing the nitrogen in my poor soil. I've purchased this brand during 2 seasons and over 6 times.

It's a little expensive but it will do my plants all season.

works like it should

Great product for our garden.Will use with our potting soil.

A must. My tomatoes do well every year

I grow and sell on a small scale. I grow over 500 peppers and tomato plants and my plants do really well with Grow Big. I like that I can just add it when I water. This is year 3 or 4 using this.
