Currently using Fox Farms line of products for indoor and they are less expensive than most other fertilizers yet produced the same results of products that cost more and are more hazardous. Arrived on time, undamaged, and was moderately priced as compared to other vendors (which did not have it available at the time).

I will admit Meta was a little easier to work with but it is growing harder to find.
I had read this product outperformed but has a more active turnover schedule.
I will admit it is very easy to use and had produces exceptional growth in everything from Kale to Chard to Peppers.
Very satisfied.

This stuff is phenomenal. Works wonders. My citrus cocktail tree was turning yellow and dying so I looked for something to bring it back. A friend of mine let me try some of their Grow Big on my tree. WOW! Within days I had new explosive growth all over the tree and older yellow leaves turned green again.

I bought it from a local hydroponic store. I only grow tomato's with it and a few squash as a hobby. I was looking on Amozob and found where I could buy it cheaper from Amozon. So I have bought many gallons now thru Amozon. Very happy!

Using this to grow lettuce and other greens with hydroponic system. Works great! I like that you just measure and mix with water, no having to mix a bunch of different nutrients, all you need is in this one liquid.

The package was damaged as for as the top was concerned. But the ingredients inside is awesome. Simply the best fertilizer for my tomato's. and any other vegetables or flowers.

I was super impressed with how they shipped it. They sealed up my lid and put it in a plastic bag surrounded by air pockets and snugly fit into the box. Very efficient

The product was broken upon delivery (pretty sure it was a mail incident) contacted seller, fixed the issue right away. Will buy more in the future
