Haven’t seen any bugs since using this stuff and I can tell already the stock and stems are more robust. Definitely a great way to get Silica into your soil.

It's the real deal, you can see the full exoskeletons of the insects, smells awful but i know my plants love it! I like giving it at the roots during transplanting!
Steve C.
I haven't started my grow as of yet. All the build a soil products that I use are all extremely effective and hoping for a good grow this summer. You guys are awesome keep up the great work.

A perfect addition to my re-ammends, top dresses and nutrient/compost teas.

I've been growing fully organic/no-till since late 2018. I switched from "Down To Earth" one of the best brands on the market, but they are usually sold out of the products I use most. So, I would get stuck buying from random sellers on Amazon for highly inflated prices, since the closest retailer is half a state away. I use mostly BuildASoil products now because of the consistent quality assurance and direct availability. There are a few grow stores within an hour of my house. So, even if it isn't on the website I can still get whatever I need. It may take a few days longer to receive the order, but it's always worth the wait.

My plants are loving all the nutrients from build a soil so wanted to get this when the sale came up over Halloween

I've been using Premium Insect Frass for the past 3 weeks. The outdoor plants, which are 3 weeks into flower, are thriving on the combination of Frass, BuildABloom and Build-A-Flower compost. This Frass will remain in my feeding schedule throughout flower to harvest.

Love this product. A good way to give you plant nutrients they can use right away

A staple for top dressing. Quality piece from the team at Build a Soil.

I use Frass for a lot of things, including teas and amend. I decided to try their Frass because I've honestly loved every single product I've tried(MANY). I like the consistency. it's not to fine or chunky. It's got good surface area and got a nice stink to it, without running you outta the garden. I've just laid it into the outdoor garden, pre-planting, and im sure it will be amazing for ipm

The plants love this stuff but mainly the soil benefits from this, definitely get it if you’re on the fence about it!
Jeremy O.
Got to say WOW when we give the girls a nice. What we call afternoon tea those girls freak out wat a response we get from that great stuff!!!
Noah S.
Just started using it. Proofs in the pudding & always hard to judge what did what but all the BAS products I've used have been great.
Elizabeth R.
Will let you know this summer how the Plants are doing.
I plan to incorporate this in my potting soil as well as adding it to my “problem “ plants that have been troublided by aphids and scale. Great product. Thank you! 🌺

Free shipping makes these very affordable for top notch frass
James N.
Stuff seems to work great, things do better with it. The bag got torn in shipping and most of it spilled into the earthbox. after cleaning it up and putting it back in the taped up bag I weighed it to see how much got lost out of the cardboard box and the 7 lb bg weighed 8 pounds.

I use this frass as my only fertilizer seed to harvest along with build a soil mineral mix. All the n-p-k your cannabis or fruit trees will desire! I’ve been a craft blend user for years and will never go back.
MATTHEW F.
My plants love the frass and a little goes a long way when top dressing
Robert S.
Everyone should incorporate these products in the indoor gardening .. I mix my own soil and amendments and practice clean.. It got rid of all fungus bugs .. It took care my immediate concern.
Jeffrey
I always add (top dress) mid vegetarian then again in the first week of flower along with worm castings. After watering the juices trickle through the root ball. Helps with strengthening stems and enhance trophic levels in my soil.
Neal
Tob dressing or in tea, this stuff is a powerhouse. Loaded with good stuff for your girls to make them strong, healthy, and pest/disease resistant.
ROBERT D.
BEST I HAVE EVER BOUGHT THESE GUYS HAVE FIRST QUALITY PRODUCTS
Kenneth S.
Smells strong at first. Don't inhale it lol
Kyle F.
Goes in the soil mixes and teas
Marco S.
It came quick and I use it in my soil. Any product I've gotten from build a soil has been amazing so I don't see this being any less then that. More than enough in the smallest bag to last a while.

Works well as soil amendment, soil top dress, or tea amendment.

I’m exited to try this product. Description and shipping were excellent. As far as results it’s too early to tell, I spread the frass about a week ago and just put my transplants in. I’ll update when I can speak about results, but I expect great results.

I amended my soil with it for next round and used as a foliar spray on my current grow.
