This bulk seed starting mix is an all-purpose potting soil for professional and hobby growers everywhere. Use peat-basted seed starter soil to kick-start produce, herbs, flowers, cuttings…you name it! It's particularly effective for starting perennial flowers and shrubs indoors before transplanting them outside.

PRO-MIX Organic Seed Starting Mix has a 6-1-2 NPK ratio, which is ideal for green, leafy growth and also makes a good fertilizer. MYCOACTIVE technology produces stronger roots to help plants resist transplant shock and general stress - and spur them to grow up to 20% larger than standard seed starting soil. The coco fiber maintains good moisture levels to prevent rotting.

Surprisingly good shirt for the price
Fit Type: Regular Fit, Color: White, Size: XX-Large
I’m generally pleased with my purchase. I got a 2XL because the website it would fit my neck. Around the waist it fit similar to Amazon Essentials work shirts (like mechanics use which I find comfortable). It was snug around the waist when sitting, but I can’t complain because I have a belly. I did find the neck snug when buttoning the top button so it means the neck is 18 or 18.5 and I wear a 19/19.5 to have 1-2 fingers space in the collar. The shirt is surprisingly thick like Amazon’s work shirts, much thicker than other dress shirts from another brand. And I am pleased that this shirt has button holes like other Amazon shirts does, all vertical button holes except the last one at the bottom which is horizontal. That feature keeps the shirt from unbuttoning itself during daily movement at the office. A very nice feature! I was a little disappointed in how it was packaged however but I have to press and wash it anyway.

Comparable to high end mens shops!
Fit Type: Regular Fit, Color: Blue, Size: Large
Beautiful, heavy blue Oxford comparable to upper end mens store at 75% less! Full cut, great for casual wear or sending out for professional starching. Downside, no pocket, but I had mine monogramed wear the pocket would be and it looks like an expensive dress shirt. I bought more (with pockets) in blue & white

Heavier fabric, very durable
Fit Type: Regular Fit, Color: Grey, Size: Large
3 stars. Pretty nice shirt but the fabric is a bit firmer than i like. I iron it when i usually wear it so that it looks half decent since wrinkle resistance is low or poor. I usually have to use a higher setting on the fabric since the material is thick making it alot heavier. Overall great for the lower end cost, anything that beats it would probably be double the price. I work in a cubicle so this works well for me, a simple shirt, with a simple color.
