HY-GEN COCO GROW
HY-GEN COCOGROW is a vegetative stage cocopeat specific nutrient. The nutrient levels are carefully balanced to ensure that ratios between all major and minor elements are optimised to maximise availability. COCOGROW contains a natural kelp extract to condition the cocopeat while stimulating and maintaining a healthy root system. It also contains additional calcium, which is essential during the late growth stage to ensure a high number of flowers are produced and retained by the plant. A lack of calcium can lead to a large number of flowers aborting before they can transition into the fruiting stage. Calcium is commonly used in the commercial cocopeat buffering process to improve cocopeat quality.
Plant nutritional requirements change as they transition from growth to flower. Having an adequate supply of easily absorbed nutrients at optimum ratios will enable a healthy transition. The presence of essential elements such as nitrogen, phosphorous, potassium, calcium, magnesium and trace elements are needed to ensure rapid stem and leaf growth while maintaining strong cell development and structure.
HY-GEN COCOGROW is also designed for use during the first stages of flowering. Use it in conjunction with HY-GEN COCOBLOOM for an optimal transition. It’s important to have a growth specific and flower specific nutrient to get outstanding results – It really does take two!
HY-GEN COCOGROW and HY-GEN COCOBLOOM from start to harvest!
WHEN TO USE
Use HY-GEN® COCOGROW during the growth stage until buds and fruit have started to form. To ensure maximum performance, regularly test and flush your system to prevent nutrient and plant waste build up.

Perfect fit for 2020 Subaru Outback
Fit my 2020 Subaru Outback perfectly. 5-minute install. Works great. My previous cabin filter was scary to see.

Good, inexpensive replacement filter
I've used these filters for a couple years (four replacements) on my Subaru Crosstrek, and they seem to do the job well, probably as well as the original. I generally remove and clean them every three months, and replace them every six.

Save some money by doing your own cabin filter change! (You won't notice a difference).
So, one day I was getting an oil change at the dealership, and the associate told me that cabin filter was pretty dirty, which I believed because of the places I take the car, and she said that they could change it while they were finishing up the rest of their inspection, since they already had it apart. I asked her "How much?", and then we both had a laugh when she said "$90." I told her I'd take care of it.
It took two days for Amazon to get a replacement filter to me, twenty minutes to watch a You Tube video showing how to replace the cabin filter on my car (I watched it twice), and then about twenty-five minutes to replace the filter itself--I keep a messy glove compartment, so a good portion of the time was loading and unloading that nightmare.
In the end, under $15 for the filter, maybe 45 minutes to watch and replace, and the cabin filter hasn't been this good since I first bought the car.
This replacement version was as good as the OE filter, fit exactly the same, there's no difference in airflow that I can tell, and so far (6 months later), it seems to be holding up pretty well. We'll see what it is like after a year. I did get the oil changed about a week ago, and the technician didn't raise any alarms about the filter, so everything seems to be working.
$90 for a new filter? You can do it yourself cheaper.

Fresh Air Upgrade for My 2024 Impreza
Installed this in my 2024 Subaru Impreza, and it fit perfectly—no issues. The air smells noticeably cleaner now, and it took less than 10 minutes to swap out. The carbon and HEPA filtration does a great job clearing out odors, dust, and pollen—definitely an upgrade over the factory filter.
The build feels sturdier than the OEM version, though it does have slightly fewer pleats. Might mean it needs replacing a bit sooner, but for the price and performance, I’m fine with that tradeoff.
If you’re looking for a quick, affordable way to improve your cabin air, this one’s a solid pick.
