MSU Orchid Fertilizer 13-3-15 Reverse Osmosis, Rain, Tap (City) Water Formula 2 Pounds

Good product. I've been using it for years. Highly recommend. Follow the instructions and your orchids will do very well.

Honestly, I didn't even put a dent in this bag for my last grow. Used 1 tsp per gallon with 1 tsp Epson salt to make up for the lack of sulfur in 13-3-15. Flower, I continued to use it with 0-10-25 incredible bulk, not exceeding 1000 ppm using distilled water (water softening system installed). Around week 6, discontinued 13-3-15 and increased incredible bulk all the way to the end. These nutes work FANTASTIC and will last me at least 3 or 4 years. Most people make surf juice with this (mixed with water in a concentrated form), but I use it straight from the bag. It is dissolveable, but I use a long stuck to stir the mixture to make the larger particles dissolve. I'm saving a whole lot of money on nutes and getting top results. This was my first grow. Looking forward to many more with this nutrient mix.

I am really looking forward to some improvement with my orchids by using this highly recommended brand of fertilizer. the MSU research showed significant improvement in growth and inflorescence compared to traditional high phosphorus and high nitrogen fertilizers. I am growing my orchids semi-hydro and using about 50ppm.

I think my African violets appreciate this new fertilizer. They have been getting way too much phosphorus in the previous African violet fertilizer and it's poisoned the mix. I like the lower relative proportion of phosphorous in this mix. Nitrogen and Potash both can leach out of the soil if there is an excess, but phosphorous doesn't move through the soil as easily. my only complaint is I think it's a bit expensive, but quality products usually are more expensive. I recommend this for violets and orchids, both of which hate urea as a nitrogen source.

Fertilizer seems to be working well for my orchid collection. But the fertilizer bag was punctured during transport. I needed to find a alternative container for storage.

I got this fertilizer a couple months ago, and have been using it at half strength mixed with rain water or purified water on plants that were showing active growth (watering every 5-8 days) . I have around 10 phalaenopsis and all are currently in spike. I never had problems getting flowers, but overall vigor in my collection has never really improved, and my plants just maintained a certain size without really growing. It seemed like the roots were thinner and the flowers smaller over the course of many years. I am astounded by the juicy hearty thick roots that have been growing since I started using this fertilizer! There's even one skinny root that all of the sudden has a big fat green growing tip. Honestly, I'm so impressed. Thank you MSU for doing the research, Greencare for manufacturing, Jim's Orchid Supplies for packaging and Tezula for having this product/size/price in their Amazon storefront. Note: I have also switched out of ceramic orchid pots back into clear plastic orchid pots in order to better see roots and judge when to water. Chronic low grade dehydration could have contributed to my plants mediocre vitality.

Haven't Use it... trying to decide whether to return it or not... I was shorted 4 ounces of the 2 pound claim! Then I had to explain to the guy who split it with me why he has 14oz and not 16, and that INCLUDED the bag weight. Making me look like a thief... serious b.s. 4oz is 1/8 of the purchase amount. I dont know how this couldn't have been deliberate. It should have been VERY obvious it wasn't the right size.

Product came dry and packed well. Exactly as advertised. However next time I would buy it more in bulk for cheaper because 2 lb is not as much as I expected and I have a lot of plants.
