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

I was skeptical when I first got this but wow am I impressed! This stuff is great. Better than description and it expanse a lot....a whole lot. Very easy to work with too. I am placing more orders. Very quick delivery too. Buy it. You wont regret it. Perfect for starting seeds, soil amendment and more.

High moisture retention, great rate of germination, love the quality of the product

Great soil, just add water and watch it expand.

This is great for starting seeds! I had five seed trays and only used half of this to fill them. After following instructions, adding water, it doubled in size.

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 performingOriginal 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.

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.

Every seed I started - dozens of tomatoes, peppers, flowers - all sprouted, and then most died. Those that lived were stunted and never made it to the greenhouse. Sterile containers, multiple racks with same grow lights, same warming pads I have had awesome success with for years… I start seeds every spring and thought I’d try this type of product. Never again. Extremely dissatisfied and disappointed. Only use true, sifted sterile seed starting SOIL. Seedling roots need a more solid medium to flourish.

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.
