I grow most of our veggies indoors under LED lighting, and one of the veggies I grow are beets. Beets require a fertilizer higher in phosphorus for growth of the beet root. Although I had been using a fertilizer higher in phosphorus, the beets seemed to be growing slowly. Using this fertilizer additive requires only 1/8 tsp. per gallon of water, so one package will last for a very long time. For my beets, I added 1/8 tsp. to a gallon of water in addition to the fertilizer I had been using. Within a week or so, accelerated growth of the beets was noticeable. I am looking forward to a nice crop of beets grown indoors. In addition to growing beets, addition of this phosphorus would be beneficial to many other plants, such as tomatoes, since phosphorus helps plants to develop a strong root system and promotes flowering. Since this phosphorus additive is concentrated, you have to keep in mind that a little goes a long way. I hope this review was helpful for you.

This product is impressive. It is granular and I used less than 1/8 tsp per gallon, mixed and then watered my blooming plants with it. The label says it will make 800 gallons, which will probably last me until I am too old to garden. About a week after application, my everbearing strawberries started developing blooms. It increased blooms on my tomato plants and squash plants as well. I'm going to do another application to see if the bloom quantity increases, but I couldn't be happier to see that it is working.

I use this Phosphorous product and the similar NPK Potassium products as macronutrient supplements in my 700 gallon aquaponics system. Rock Phosphate is the usual product recommended for an aquaponics application but this product does not turn the tank water brown like the rock phosphate does. The reason for the supplementation in an aquaponics system is that the only other products that go into the closed system are rain water and fish food. The fish food provides enough supplements for the fish but not for the plants. I have been using about 1/2 teaspoon of this product about once a week for about a month. The cucumbers, tomatoes, lettuce, celery. and kale have all experienced explosive growth. I plan to back off on the dosage now before the cucumber plants try to grab me as I walk through the greenhouse. They have already tried to climb over the top of a 6ft trellis and leave through the ceiling vents.

My plants, especially those that are flowering and fruiting, have shown a significant boost in vitality. The blooms are more vibrant, and the fruits seem healthier and more robust. It's clear that this raw phosphorus is providing them with exactly what they need to thrive. Overall, I’m extremely satisfied with the results and would highly recommend raw phosphorus to any gardener looking to enhance the growth and productivity of their plants. It's definitely earned a permanent spot in my gardening supplies!

Great for custom feeding.

This is by no means for beginners or just a couple of grows under your belt. This product will burn your plants right out if used wrong. Things you'll need in the beginning before understanding the application. A scale a calculator and knowledge of conversion into grams. Then you'll know exactly how much to at to your water especially if you're using less then a gallon of water. I use it once a week with Coco and no other nutrients added with it. It's worth it and definitely helps but don't think it's going to give giant buds.

Got this today, so I don't know the plant impact yet. What I can say is that it dissolves quickly. I used an 1/8 tsp per gallon to a small amount of water, it dissolved quickly. Then it went into a 10 gallon hydroponic nutrient tank for distribution. I purchased this to see if would help my Swiss Chard which was turning a funky color in my new grow system. Time will tell! Edit: The Swiss Chard returned to their normal green color and are looking very healthy.

It didn’t really make my plants bloom more.

All the raw products are excellent. I consider all the RAW supplement line to be one of the best for the price range
