4 oz URB Natural Super Concentrated Organic Microbes, Hydroponic Nutrient, Phosphorus Bloom Booster by URB Sciences

I have only had a chance to use once (directions say use weekly and just recently got it), but I noticed a very positive difference in my plants just hours after use. Not the next day, 3 or 4 hours later! They were noticeably perkier that quickly. If you're new as I am to growing and aren't sure exactly what to get, do not skip this product. It makes a very real difference very quickly. You won't be disappointed. Also, paid full price for the sample size product and received nothing at all in return for my review. I'm pretty leary of reviews being biased myself. This one is not. Good luck potential Dr. GreenthumbsUpdateThey are still responding well to the URB. Have used for 4 feedings so far. Not as drastic difference after the first use but still definitely makes a visible difference. Highly recommended.

It didn't work. My plant got super dark and the tips of the leaves got brownish and yellowish. My friend is using sea weed liquic extract and his plants are looking way better. I also emailed the company and let them know to be ignored. I used this little bottle as intructed... I wish I could have check the PH but I was so excited I used it all then I notice the unwanted results.

This stuff is incredible.My plants are beautifully healthy and the root growth is just explosive!If you are using any kind of living soil,do yourself a favor and grab the sample.I'm grabbing another gallon.I did inoculate with 30ml first feeding and use 10-12ml every feed since.I use Chicken Soup for the Soil and TPS nutrients organic calmag along with reverse osmosis water.I highly recommend those too,the chicken soup for the soil is great stuff, although it isn't on Amazon,Google it.

This is amazing! Plants love it! I even used it to clone my plants. I just dipped the cutting straight into urb and this is a week later. First time cloning and found out I was supposed to use clone gel. But I didn't and look it worked, wow!! A must to use in your tea! Love it bought this small 4oz to see. I will be buying the biggest one next time. You get what you pay for and so Worth it! All I can say just look at my clone and my 4 wk mother plant stem. Very impressive! Stop reading reviews and buy it!!!

Wife gave me a flying dragon plant for my birthday a few years ago. I kind of neglected it and the soil it was in outside was not great. I just replanted it closer to the house. Im using this URB liquid to introduce some beneficial bacteria into the soil in hopes I can revive this plant. After about a month it is starting to get green leaves and seems healthier. Have had to adjust the water PH when watering as this plant likes more acidity but our water is close to 8ph. The URB brings the ph down .

Wish I would of got the big bottle, this stuff has my seedling outgrowing their pots super fast. Gonna try this in a compost tea next.

An amazing product geared toward goodness.Don’t deprive your plants by withholding the dipping sauce.Much props to the crew.Happy growing!

First time using this. Will definitely not be the last. Added this to my feedings. Plants are incredibly healthy with some incredible roots. One of the benefits of pheno hunting is inspecting the roots of the not so fortunate plants.
