Supercharged seaweed


Grosafe doesn't just use any old seaweed. OceanFert uses a pure form of Ascophyllum nodosum. A highly valued brown marine seaweed prized for it's dense nutrient profile.

Packed full of bioactive compounds, rich in natural plant growth hormones, high in macro- and micro-nutrients.

Used for agriculture, animal feed and human dietary supplements, but in this form just stick to using it on your plants only!

 

What does OceanFert do for plants?


Boosts root & foliage growth


Natural source of auxins and cytokinins. Promotes growth of stronger, more active roots with a larger surface area, and boosts foliage growth.

Stronger, hardier plants


Promotes cell division while delaying aging, creating a stronger root system and longer-lasting, hardier foliage.

Healthier, more fertile soil


Improves beneficial microbes in the soil, improves soil pH and texture, adds aeration and improves drainage.

Boosts pest and disease resistance


Makes plants less attractive for pests to feed and breed. Acts as a natural, organic biopesticide making plants less palatable to pests.

Naturally thickens roots, stems and leaves acting as a natural barrier to harmful fungi and bacteria, root-feeding and sap-sucking pests like root mealy, mealybug, mites, thrips and more.

Supports the good guys. Enhances growth of beneficial fungal and bacteria in the soil.


Improves nutrient availability & uptake


Makes nutrients more available to plants. A natural chelator (said 'key-late-tor') that unlocks nutrients, making nutrients more bioavailable for roots to take in, boosting nutrient transport within the plant.

Need lots of connectivity + charging. EXCELLENT.
Color: Gray
Problems with my original USB hub required something better. This unit has allowed me to connect all my peripherals to my laptop and I haven't had any problems with the USB port reliability I was dealing with. I'm using two hubs in series and now everything is working perfectly.

Yes, I wish I'd bought this on Black Friday, but still no regrets
Color: Gray
If you use a lot of add-ons like I do you won't regret buying this hub. The number of connection PLUS high power charging ports works for me. Printer, scanner, mouse dongle, phone, tablet, external drive, flash key all connect with zero problems to my Win 11 laptop. Saves my laptop ports from wear and provides a central location for charging my stuff. Solid metal construction, touch switches for each port, even slots forSDd and micro sd cards makes great design and features. Had a decent usb 3 hub but this one SO much better, good value

well made, nicely built, fast and everything fits firmly
Color: Gray
Sleek and well made, heavier than my old one, as it seems better built in every way. I love the flush power buttons, they don't get accidentally pushed in because of the firmness of the buttons, not hard, just not overly easy like some cheaper hubs. The color is nice looking, the lights are subtle but easily identify each port and the main thing, it's fast. My old USB hub was decidedly slow and often under-powered. It did not always work with some demanding devices. But as soon as I plugged this in, all my devices were recognized and worked correctly. This was a great buy.

Had some questions and needed to test it, here's the verdict!
Color: Black
No pictures, but I wished to get this review out as soon as possible because I'm very happy with my purchase. My last USB hub from aother brand broke immediately as soon as I got it which is why I wanted to purchase this as an "upgrade" for the higher voltage and more port options. Firstly I really appreciate that they gave both a USB 3.0 to USB-C and a USB-C to USB-C cable for the power depending on what type of port you have on your computer. The extra cable is always appreciated. I had a bunch of questions stemming from other reviews so I tested them. When you press a button nearby any port, the light goes on. When you hold it, it goes off. When the light is on, it powered my external drive, and when I hold-pressed it off, the drive on my computer disappeared as it should when no power is going to it. I'm glad that works perfectly. Also, it takes 16 seconds to recognize my 8TB drive. It seems a tiny bit long, but not too long, I'm pretty patient. For the SD and Micro SD card slot, there is no on and off power buttons. But they DO work. This was important for me as it was one of the reasons I bought it. The quick charging also works as intended. Also, I wondered what size it was- it's 8.75in long, 2in width, and a measly 0.65in heightwise. Every cord included is slightly larger than 3ft so there should be no problems with connecting it, though maybe it's too many wires for some. One thing I was concerned about was that a reviewer said the ports were very tight, and they are. I thought I was gonna break the ports by connecting a USB, but thankfully it didn't break. I don't know how realiable that is over time, though I imagine because of the buttons, the idea is to connect them once and if you want to not use it, to simply press the button to turn them off. So I think I'll do that once I get all my USBs set into place. If it breaks any port in that process down the line, I'll update my review. And based on the manual, here are the speeds: USB 3.0 & USB C - Max 5GB/sec data speed, Max 5V/1.5A power SD and Micro SD Slots - Read 50-104MB/sec, Write 30-80MB/sec (Subject to memory card speed and computer USB ports) USB QC Ports - No speed or power given Total power supply: Output DC 12V/7.5A (Input AC 100V~240V / 50Hz~60Hz / 2A) The power supply is a big brick LOL. But I appreciate the power, thanks. It's very easy to use overall, I just plug something in, turn the light on, expect it to work and it does. Besides it taking great force to plug a USB in, everything else is exactly what I wanted. Glad I bought this. Edit, a month or two later: The USB ports all still are working, but I noticed some external drives don't have enough power to work, even with the 8V, so I'm docking a point. I should be able to plug at least one in with a few other things connected, but this makes it a little less functional for my usage.

Just what I needed
Color: Black
Never given!give 5 stars. But, this got it because exceeded what I was expecting. Purchased because new computer slots were inconvenient and more new devices are using usb ports and having powered ports was essential. Have used for several months and keep finding more things needing it. It was more than I expected/needed at the time .But, was designed for growth I was not expecting. Getting excellent connections, speed, and reliability even though I’ve nearly doubled the devices I planned on using. To be clear the system I connected to is all about performance and top of the line hardware. I was a performance engineer in a previous position and am very picky with this system setup. I’ve tested the hardware several times tuning things and it’s never the bottleneck. The original purchase was intended as a short term fix when I needed something yesterday and as stated b4 it has earned a place in my permanent setup. Would buy again and would explore other offerings by manufacture.
