Ocean Solution 2-0-3 Organic Liquid Fertilizer

OMRI-Listed • Hydroponics & Soil • Great for Microgreens

One of our go-to fertilizers for growing microgreens. Ocean Solution 2-0-3 consistently delivers stronger growth compared to many other nutrients we've tested specifically for microgreens, and it's OMRI-listed for organic production.

What It Is

Ocean Solution 2-0-3 is a liquid organic fertilizer made from OS PURE, with naturally sourced, OMRI-listed nitrogen and potassium added. The formulation helps plants readily absorb both macro and micronutrients, supporting steady growth, overall plant health, and efficient nutrient uptake.

Why It Works for Microgreens

Performs exceptionally in hydroponics: While effective in soil, this fertilizer really shines in hydroponic systems. It mixes cleanly without clogging systems or leaving stains—critical for trays, reservoirs, and recirculating setups.

Clean formula: No sediment buildup, no staining on silicone grow mediums or trays, no clogged mesh. Just clean, consistent feeding.

Easy to dial in: Simple mixing ratios that work reliably. Once you find your preferred strength, results stay consistent crop after crop.

OMRI-listed: Certified for organic production, meeting strict standards for organic growing operations.

How to Use

For Mature Plants & Garden Use:

  1. Shake or stir well before use
  2. Mix 1 oz per 1 gallon of water
  3. Apply to roots or foliage
  4. Reapply every 7–10 days

For Microgreens (Our Method):

  1. Start with a food-grade bucket
  2. Fill with water
  3. Add 0.5 oz per 1 gallon of water (lighter rate for microgreens)
  4. Mix well
  5. pH balance to 5.5–6.0 range
  6. Use for bottom-watering trays after germination

Note: The microgreen rate is half the standard rate. Microgreens need less nutrition than mature plants and perform best with lighter feeding.

When to Use

Hydroponic microgreens: Mix nutrient solution and use for bottom-watering after germination is complete

Soil-based microgreens: Mix and apply as needed if growing in low-nutrient mediums

Garden plants: Standard 1 oz per gallon rate, applied every 7–10 days

Recirculating systems: Clean formula won't clog pumps or leave residue

An effective TV watching enhancement
Size: 7.8FT for 40''-50'' TV
The Govee TV Backlight 3 Lite transformed my TV-watching experience. Installation was quick, the adhesive holds well, and the calibration process is a little tricky and will take time to get right, from mapping out the TV size to setting the light quality up within the app. But the light quality is good and works best in rooms which are very dark with no external light sources to influence the color the camera picks up. The ambient lighting makes movies and gaming feel more immersive without being distracting. The app controls are intuitive, and the customization options let you fine‑tune everything from brightness to color modes. If you want an easy, affordable way to elevate your TV experience, this backlight delivers as promised.

One of my favorite purchases ever.
Size: 11.8FT for 55''-65'' TV, Size: 11.8FT for 55''-65'' TV
So I bought this backlight a few months ago and it's been one of my favorite purchases I ever made on Amazon. Honestly, once you start using the backlight, it's so hard to go back. It makes TV and games just so much more immersive, especially when there are bright scenes and the lights flash, or when there are dark scenes and it just goes completely black. The setup is really easy but it does take some precision to get it right the first time and to keep it working for a long time. And sometimes the things that stick the wires to the back of the TV do like to fall off. Although that may be a consequence of how my TV is built. I think it looks best in a darker room where there's less space for the light to go away, especially when the TV is against a wall. But that's how I use it, and it's been just an amazing experience. The app functionality is also pretty good, although I don't use it as much these days and I just keep it in TV syncing mode. The lights can get really bright, so if you want to, you can use it as a separate ambient lighting for your room. Although personally, I think that's too much effort and I just use my lamp. Coming from someone who uses his TV a lot, if you're on the fence, just get it

Movie lighting must have.
Size: 11.8FT for 55''-65'' TV, Size: 11.8FT for 55''-65'' TV
This is exactly what it was in the listing. It was very easy to install they stick to the back of the tv very well. The lights strip is good quality and they wont fall off the tv even from the heat.. The app is easy to use. Will say there are a lot of options to control it from the app. Once the control box is behind the tv your not going to be reaching back there to turn it off and on. I have mine connected to Alexa and Google so i can control them with my voice. They look great for watching movies even in a somewhat lit room. Be mindful of the camera on the top of the tv I did have to calibrate it 7 times cause it wasn't picking up all the corners and i accidentally hit the camera while walking around if your tv is on the wall you have nothing to worry about unless you have my first issue of it not catching the corners properly. The little orange squares don't stick too well especially since i had to do this several times. Even tried it without the squares and still had problems. The video was recorded after the second time of calibrating it. The problem comes when you try to get the hue right. Everything white makes the lights turn red so i had to mess with the saturation and the white balance on color calibration feature on the app to get it as close as possible to the white on the tv and its still something i have to adjust ever time i watch something.(Shown in the second picture)

Amazing!
Size: 11.8FT for 55''-65'' TV
I absolutely love these lights. I will never go back to no lights again haha. Perfect for movies, shows, video games. Also super easy to get it installed. The only issue we ran into a little bit was the app and trying to get the tv shape and layout registered.
