Midwest's Wild Horse Bulk Substrate Manure Booster (HRS1)

5.00 stars, based on 22 reviews
Midwest's Wild Horse Bulk Substrate Booster is the easiest way to supercharge your bulk grow! We've used manure for years but nothing comes close to the performance of this kind. In fact, its so potent you only need to add 1 pound for every 10...

Pros:
  • effective
  • cost
  • bigger flush
  • higher po
Cons:
  • can't think of any
I was skeptical when I first saw this product but figured there wasn't much to loose. HOLLY S***! I was wrong there is alot to loose by NOT using this booster on every grow. not only does this product increase yield but the size of the fruits are enormous and they are incredibly potent. the 2nd flush was starting to grow before I even had a chance to harvest the 1st. One word of caution, if you use this you may want to get taller tubs.

Damn Good Substrate Booster!

Pros:
  • Price & Quality
Cons:
Was looking for a product that I could blend into my coco coir to hopefully retain moisture and increase pinsets. I’m pleased to say after some side by side comparisons with a normal coco coir bulk sub & others amended with this product, it speaks for itself. Great job Midwest Grow! Will continue to purchase from ya’ll. Keep kicking A$$ !
