Back to The Roots Organic Seed Starting, Compressed Block expands to 12 Quarts, Made for Herbs, Veggies, Flowers

This is the only one I buy because it's SO good. Our plants love it, we've seen zero bugs/fleas, good moisture retention. I'd say it's fair value for the cost.

This Back to The Roots Organic Seed Starter is really easy to use and a good value. It retains moisture well and expands to fill several pots (12 quarts). It has good consistency and some of the seedlings appear to be starting to sprout. A good value for a nice-sized block of compressed starter, I would purchase this product again; five stars from me.

This seed starting soil is legit!!! I planted cucumber seeds, a few herbs, and they sprouted in just a few days! No cap. I was really impressed and just planted an avocado pit to see how it grows. Total aura, thanks back to the roots!!!

Omg this stuff is amazing!!! It even comes with a stirring tool and little scooper...perfect for my little green house seeding starting trays!

UPDATE: while seeds germinated faster with this mix, the seeds planted in MiracleGro seed starting mix did all eventually germinate and in fact are now looking much more healthy than the Back to Roots mix. Top 2 rows in second photo are in miracle gro mix, bottom 2 rows in back to roots mixture. I’m changing from 5-stars to 4 only because I think the miraclegro seed starting mix is out performing Original review: 100% germination of tomato seeds with this mix vs about 65% germination with Miracle Gro brand seed starting mix in same environment. Used covered tray with grow lights, warming pad and “Cow Pots” 3” pots.

Worked so well for seed starting! I had so many seeds germinate (once I learned about proper soil temps) and grow lights. The plants even seemed pretty happy for a while when I was lazy about transplanting to indoor potting soil. Might have stunted their growth a bit without nutrients but they did pretty well. Bottom watering is definitely the way to go as it get very soggy with too much moisture. I’ve also started so many seed trays with just this bag. I wish it resealable.

Not impressed. I was looking for rich, fluffy seed starting soil and that's not what this is. This has almost as much mulch shreds in it as other potting soil and that's what I was trying to avoid.

I got this to start seeds in, and ended up mixing it with other seed starting soil. It was too chunky with big pieces and it seemed to hinder my seeds from growing too easily. I did like how it held on to the water though, so I was careful to keep big chunks out of the seed cells. I wouldn’t buy again when there are other options that you won’t have to deal with big mulch like chunks.
