A note from BuildASoil

Over the last 13+ years, we've grown into a much better company — and a lot of that growth came directly from our critical reviews. Every 1, 2, or 3-star review on this page taught us something. New formulations, better packaging, improved shipping, clearer instructions, stronger customer support — almost all of it traces back to a customer who took the time to tell us what wasn't working.

If you haven't tried BuildASoil in a while — or you tried us early on and it didn't go great — we'd genuinely love another shot. We get better every year, and we have the receipts to prove it. See what's new at buildasoil.com →

It works! However after opening the bags a handful of times, the ziplocks peeled away from the bags rendering them useless. Poor craftsmanship. So unfortunate since they work so well.

Terrible quality and misleading description. These trays cost a buck or two at your local grow shop. Unbelievable to be charging $15 for such a cheap tray that doesn’t even fit standard holders.

This product caused repeated leaks and flooded my tent within days of use. Support sent multiple replacement parts (tube/grommet, and then a replacement tray), but each one still leaked. After more than a month of troubleshooting, I’ve lost all confidence in the product and am seeking a full refund.

I love the covers. However, after a year my zippers are frozen. I tried everything to free them with no success

Good product but for nearly $200 i was sure it came with a Grassroots bed. The tray2grow and bed combined everywhere else go for $180. My mistake but charging almost $200 for a product you can get for $99 every day of the year isnt a great look. I’ll oay a little more for a small business but this was too much.

I'm sure it is providing a benefit, I decided to go with Rooted Leaf products instead. Sorry but I want to try a new direction.

I ordered two of these for my magnolia six lights with the manual dimmer. Upon receiving it, I learned that it was only capable of running one of the three lights the board has.. in other words I would’ve needed to purchase and Daisy chain six of these together for it to function as described. …. At this point, I was truly at a loss and had to make a deal with the devil himself, Jeffrey Preston. I begrudgingly ordered a pair of three into one barrel pin connector on Amazon three female to male…this time to find out the only one they sell has the incorrect size of male barrel pin, being just slightly too large to fit. After further scouring the Internet, I realized I was on my own. I will say it is worth mentioning that Jeremy reached out to me personally to try and help with the issue. I removed the back of the unit. Build A Soil sent me ..removed the barrel pin connector and hardwired the 3 into one into this unit. To my shock, as I never been good with electricity… it worked.

No there is nothing inside that can develop, no larvae. But once you use the kashi gold it will seriously ramp up life in your soil and can attract flies and other things from your surrounding environment. I hope that helps you undertand what could happen. Also, animals love this stuff so keep away from your dogs and store where mice can't find it. Thanks!

Bugs were packaged and shipped exceptionally well. They arrived very much alive and vigorous. I have used Rove Beetles in the past with good success, from other vendors. These ones seem to be getting going a little slower than my previous experience. I did water a little heavy shortly after, like 12 hours. So it could be my fault.

Good morning Chuck, Even though you did not buy your Highgrove Light through us, but rather LED Lights Grow Depot, we are still working to resolve this for you with Highgrove. We appreciate your patience.

So I purchased the whole seeds to grind myself . I dropped some seeds on the floor so I just threw them in my soil whole. Na few days I had corn and barley sprouting . That being said these are supposed to already be sprouted to get the benefits of the sprouted seeds . I think a little more quality control is needed to make sure theyre actually taking the time to sprout the seeds .

Other then the 6"squares being too big for my liking I dont have much to complain about . If they was smaller the trellis would b perfect . And a little pricey.

It doesn't seem that you should need to buy insurance to receive your package. I buy it every order but I don't like the idea at all!

I just purchased this product in the run. I’m doing now has just been harvested. I only use Build A Soil products and a few others and they work fantastic. I have total faith in the products. BAS is offering to their customers so I’m looking forward to using this product and I cannot wait to see the final results.

I am accustomed to worm castings being dark in nature and not brown. I did expect the bio char, to be in chunks and not finely ground. Will wait for the affects end of season.
