Back to the Roots 3-in-1 Seed Starting Mix 6 Quarts, 100% Organic & USA Made for Herbs, Veggies, Flowers, w/Nutrient Rich Plant Food, Worm-Castings, & Moisture Controlling Yucca Brown

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 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.

It's like magic, pouring water into it, the coir grows and grows and....and if you need more than what's under the surface, keep watering. Amazing, that there is so much in this small, square package. I actually was surprised because I didn't realize I had ordered the compact version. Normally I buy Back To The Roots in an already reconstituted state. However, I think I'll buy it this way from now on. Used what I needed for indoor plant seedlings, a little topping off of my houseplants for esthetic reasons, and then added the rest to my outdoor garden. Instructions say to add about a gallon of water. If you don't think you are going to need the whole brick, water a little at a time and you can always add water.

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!!!

I really like this product. My seeds are coming up really well. I have used it in pots as well as trying my hand at seed snails. It was a real good value for the price. I only took away one star because I went to order another package and it went from $7.99 to $11.99 in a week. I'm not thrilled about that.

I’m giving this product 5 stars because it really works. I germinated snapdragons from raw seeds and it definitely works. For myself, I don’t live that it comes in a block that is really difficult to break into smaller pieces. The product description says you can use what you need, that you dont have to wet the entire block at once. It is true but it’s really difficult and really messy. You cant just break off what you need and save the rest. I’m giving this product 5 stars for its effectiveness but I personally won’t buy it again. It’s just too difficult to use and to store. You can see my baby snapdragon sprouts in this pic which was taken only 5 days after germinating.

I typically like Back to the Roots' products, but this one is a huge pass from me. I started my first tray of seedlings in this mix and a second tray with another mix - both were otherwise kept in the same growing conditions in a controlled environment. I'm giving 3 stars only because, technically, most everything germinated. However, this mix had so many huge chunks in it and most of the seedlings suffered from damping off (I actually grew a mushroom in one cell) or just plain struggled beyond the initial germination. They were not overwatered, and were actually bottom watered. This may be fine as a potting mix, but for seedlings vulnerable to mold/fungus (they're not so vulnerable once a bit bigger) I'm sticking to something that is more sterile.

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.
