Not every nutrient gap looks the same. If your soil test is showing adequate nitrogen and phosphorus but your fruits are undersized, your Brix is low, or your root crops aren't bulking the way they should, potassium is likely the missing piece.
Micro 5000 Organic™ is a focused 0-0-15 foliar spray that lets you address potassium deficiency directly, without throwing off the rest of your nutrient balance. Derived from kelp and OMRI-listed for certified organic production, it's a clean, targeted tool for orchards, vineyards, vegetable operations, and serious home growers who know what their crops actually need.
1 package ~ 150 grams
Why Use Micro 5000 Organic™?
- Targeted Potassium Delivery: At 0-0-15, this is a pure potassium fertilizer, but combined with beneficial living microbes for increased intake.
- Critical for Fruit & Root Crops: Potassium drives fruit sizing, sugar development, and shelf life in crops like tomatoes, peppers, grapes, strawberries, and fruit trees. For root crops—potatoes, sweet potatoes, carrots, and beets—it's essential for bulking and storage quality. If you're growing either, these are some of your most potassium-hungry crops.
- Foliar Speed When Timing Matters: Potassium deficiency during fruit set or root bulking can cost you yield and quality fast. Foliar application delivers nutrients quickly, which is critical when you're in a narrow window and can't wait on soil applications to catch up.
-
Safe for Organic Production: OMRI-listed for certified organic production systems.
How to Use:
Can apply up to 150 grams (1 package) per acre, mixed with ~ 20 gallons of water. If you wish to split applications, you can do two applications of 75 grams, mixed with 10 gallons. Can be applied multiple times throughout the growing season, depending on your crops and soil fertility.
Tips for Best Use:
- Get a soil test first. Micro 5000 works best when you've confirmed a potassium deficiency or know your crop's K demand is outpacing your soil's supply.
- Spray in the early morning or evening when stomata are most open and temperatures are cooler for maximum absorption.
- Time applications around your crop's peak potassium demand: for fruiting crops, that's fruit set through ripening; for root crops, it's during active bulking.
- Avoid applying when rain is expected within a few hours, as this reduces how much the plant can absorb before it's washed off.
- Pair with Spectrum + Myco™ at planting to build strong root biology. A well-functioning root system makes your entire fertility program more efficient, foliar included.

Amazing. Ordering more
Color: White, Size: Standard (Pack of 4)
These are amazing and the price is crazy. I'm buying a few more sets. The color is white/white, which I love. They are so soft, not flimsy at all. A great value. Well made, the seams are well sown and the envelope casing even ups the look

Soft, Luxurious & Perfect for Hair and Skin!
Size: Queen (20" X 30"), Color: 11 - Light Turquoise, Number of Items: 2, Size: Queen (20" X 30"), Color: 11 - Light Turquoise, Number of Items: 2
These satin pillowcases are honestly amazing. The material feels super soft, smooth, and cooling on the skin, and they make my bed look so elegant and luxurious. I bought them mainly to help protect my hair from frizz and dryness, They’re also very comfortable to sleep on and don’t feel cheap at all. The color is beautiful in person, exactly like the photos on Amazon. I washed them already and they still kept their softness and shine. Definitely worth the purchase for the price I would 100% buy again and recommend to anyone looking for cute, comfortable satin pillowcases.”

Budget friendly satin pillowcase
Size: Standard (20" X 26"), Color: 18 - Lavender, Number of Items: 2
This satin pillowcase is a great budget-friendly option! While it’s not quite as luxurious as my Blissy pillowcase, it still does a really nice job—especially for the price.
It has that smooth, silky feel that helps reduce hair frizz and feels gentle on the skin. It’s also easy to wash and holds up well, which is perfect for everyday use. I especially love using these for the kids—they get the benefits of a softer pillowcase without worrying about ruining a more expensive one.
Overall, it’s a solid, affordable alternative that still feels nice and does the job. Great value and perfect for families!

Super soft and durable, but keep your steamer handy!

I’m really impressed with these grey satin pillowcases! First off, the packaging was adorable, making them feel like a little treat to unbox. The texture is incredibly soft and feels great against my skin.
In terms of maintenance, they’ve held up perfectly through the wash. I followed the instructions (machine wash on gentle cycle and tumble dry on low/fluff), and they came out looking as good as new. The only real downside is the wrinkling. Even when I remove them from the dryer promptly, they tend to wrinkle pretty badly (see attached photo). If you don't mind a quick steam or a few creases, these are a good value!

Fantastic satin pillow cases for the price
Size: Queen (20" X 30"), Color: 02 - Pure White, Number of Items: 2
Edit: I already put five stars in the first place, but I was unfair to these pillow cases in my initial review! I thought they were a little warmer than the natural silk, because I was sleeping on them with acrylic pyjamas on. I have come to realise the pillow cases are not warm. They are truly excellent in every way. I just get sweaty every time I wear acrylic pyjamas! I have already ordered two more sets of these (and have switched to micrfibre pyjamas)!
Original review: First off, I want to address a popular misconception. Satin is a weave, not a fibre. So polyester satin is real satin, and it is very common. To all the people saying the makers lied about the fabric, they absolutely did not!
I bought these and I bought some inexpensive silk ones at the same time. I have been loving the silk ones and only started using these lately. I'm happy with all of them. These are not silk, and I can feel the difference, but they are a nice, smooth polyester satin. The white colour is indeed a pure white. I machine washed mine and hung them to dry. They did not wrinkle, pick or pill, and they did not change in colour or size. They look fresh and pristine. I measured my pillows and got the right size. They are pretty and neat, they seem to be well sewn and well finished, with no hanging threads. They are very soft to sleep on and did not make my dry, curly hair frizz up. I slept on them without my protective bonnet, so I got the full experience! Honestly, with the smooth, tight weave of the fabric, they may be superior to the real silk in terms of babying my skin and hair. However, they are a little bit warmer. That is fine for now, since the weather is cool. I might just use these while it is cool out and switch to silk in summer, or I might continue to alternate, we will see. Overall, I am happy with my purchase and would buy them again.
