Review: Works good. - My flowers are doing great this year since I’ve started using this!
Review: Simple, effective, natural. - This product has blown me away. It is organic and all natural, so don't let the fact that it is not OMRI certified organic throw you off. It is merely a formality anyway, stamps don't make your plants grow better. I grow vegetables in containers on my patio. This has a lot of advantages, less bugs, less disease, but to keep my plants happy the biggest struggle is giving them healthy, balanced amounts of nutrients and water. I thought I was going to be able to get away with using a cheap pelleted fertilizer, but obviously using 5 gallon pots, you can only add so much more volume without also changing the composition of the soil you have it in. I have used organic mixes before adding contents of 5 bottles together every morning, but that was so time consuming. What to do? Enter this product. One single bottle, easy proportions, instant results. I'm not kidding. Instant. Results. I had a two leader Brandywine tomato in a 5 gallon pot that was six foot long on either side. It just one day decided to stop producing new tomatoes and the small green ones refused to grow and I thought I was going to have to throw it away and get a new one. Since I didn't have a seedling to immediately replace it, I tried out this product before sending it to the worm bin. Two tablespoons for two quarts of water. By the next morning I could tell the plant was revived, once again stretching itself skyward. By the second morning the seemingly stunted tomatoes started to inflate! I was really impressed. I had planted cucumbers in cheap soil trying to save a few bucks, and what a disappointment that was. I used the "Tomato and Veg" from this same product line, and watched those guys spring to life. I'm really a believer. I chose it to start with because it is the only one step liquid fertilizer with calcium, and anyone who has grown paste tomatoes knows this is a must have, especially in Texas when plants are often calcium deficient even where there is adequate amount in the soil. Natives all across the Americas used to use fish to fertilize their crops and this product has followed suit.The smell is NOT bad. Call me crazy, but I kind of like it. It smells like the ocean after you have applied it, a testament to the freshness of its most sea-derived ingredients. It doesn't linger either. I cannot speak to it's efficacy as a foliar feeder, but for my purposes, this product is perfect. For every fruit producing plant I have in a five gallon pot, I mix two tablespoons of this product with half a gallon of water and feed in the morning. For tomatoes and other heavy feeders, do this two days in a row, and water every third day. Make sure to water enough to have some run off out of the bottom of the container and you'll have beautiful tasty veggies in no time!

## Questions & Answers

**Q: How much of the diluted mixture do you feed to vegetable plants like tomatoes, eggplants and peppers?**
A: 1 oz per gallon of water. Figure 1 gal mixture feeds 4 plants every week.

**Q: Is nature harvest tv 191 also organic?**
A: No. Not organic. See neptune harvest web site.

**Q: Can i spray directly on flower**
A: Hi Nguyen, and thanks for reaching out with your great question.  The Neptune's Harvest can be sprayed on plants, please be sure to follow the directions and dilute it properly.  You may see a slight film left behind that will wash of foliage with water.  If you spray a white flower (as opposed to the foliage) directly it could leave a stain, so be careful with that.  It will not harm the plant but can be unsightly.  Thanks for considering our products, and be well.  Joe Magazzi, Grow It Naturally LLC

**Q: Will these work for dahlias?**
A: Yes you can use these for you dahlias.  I used these fertilizer last summer every other week to all my flowering plants.

### ⭐⭐⭐⭐⭐ Seeing an improvement in my tomatoes and peppers since I have been using this plant food.
*by J***. on April 9, 2022*

I have been growing a number of veggies, greens, and herbs in my basement under lights for almost 4 years. Until the last few months, I have used chemical fertilizers. My plants have done well, but over time, chemical fertilizers build up in the soil, and the soil has to be flushed to reduce the buildup. Since many of my plants are grown in 10 gallon pots, this can be a difficult task. I have been using this plant food for my tomato and pepper plants when they are in the flowering/fruiting stage for a month or so, and have seen a marked improvement in my plants and the tomato and pepper production. I have been using 15 ml's (1 tbsp.) per gallon for every watering. Not only have I been getting more tomatoes and peppers from my plants, but the fruits have been larger. In addition, the plants are fuller and look much healthier. My last bell pepper harvest from 9 plants was 102 peppers. Since these plants are almost 2 years old and have been grown indoors, I think that's pretty incredible. UPDATE 05/05/22: Since the cherry tomato plants have been so productive, we haven't been able to use all of the tomatoes they produce. Even though I have been using them in casseroles, salads, tomato soup and spaghetti sauce, I still haven't been able to use them all. I have 4 gallon baggies of cherry tomatoes and 2 gallon baggies of the larger tomatoes in my freezer for future recipes. So, I started giving them to a local food pantry rather than freeze more of them. Last week, I collected a gallon baggie for the food pantry, and one week later, there are so many red tomatoes, it's hard to believe they had been harvested only one week ago. I will be harvesting another gallon baggie of the cherry tomatoes for the food pantry this week. Since I have been using this plant food, my tomato plants have been producing more tomatoes and the tomatoes are much larger than they used to be. I also have a couple of beefsteak tomato plants that had deteriorated and I was going to throw them out. After about 4 weeks of using this plant food, the beefsteak tomato plants have grown back and now have quite a few flowers and tomatoes on them. Again, keep in mind, all of these plants are grown indoors under LED lighting. I have added some pictures of my tomato plants. In the picture of the large plants, the two on the right were nothing but 4' stems 4 weeks ago. Now the foliage has grown in and they have flowers and tomatoes on them. The cherry tomatoes pictured had no red tomatoes on them one week ago after I harvested. At this point, I am totally sold on this brand of plant food, and would highly recommend it. I hope this review was helpful for you. I will update the review if my opinion changes.
