    Grower 101

    Posted by L Charles on Dec 9th 2016

    On my second grow..first try had lots of problems. After doing LOTS of research had come across this product and thought it was worth a try since I could use all the help I could get.. lol. I think part of my issue was the O2 levels. I used hydrogen peroxide, but think I miscalculated and screwed up my plants. This DO was way easier to work with.. I mean all I had to do was add it my formula.. nothing complicated.. and believe me less is more in that department, if you get my drift. Anyway, I'm not finished yet, but in way better shape than last time. So I think this DO helped so far. In the beginning I was having a real problem with my pH but this made it easier for me to keep at prime levels. I think that was also my problem with my first grow, from the beginning things were a bit off, and only got worse as it went. But this time, my root system developed faster, and in good shape. Moved them to pots a few weeks ago, they're healthier than my last time at this stage .. and bigger too.. and feeding a lot! Feeling really positive about this grow! Only problem is it's hard to find this product, so I have to order direct from the company, which isn't so bad, but sometimes you need it right

    Direct Output

    Posted by Peter Ross on Nov 30th 2016

    I was very skeptical about this product. I mean how long have I been searching for a clean, easy to use O2 product, that didn't do damage to my plants. But my buddy suggested I try this product. It was a little pricey, but he swore by it. Honestly, I couldn't believe the results. It cut down days on my root development, and my plants were healthier than anything I've ever grown.. pretty wild stuff. I would totally recommend this product to anyone who wanted to get more oxygen into their growing regiment. 5 star's for me.

    Direct Output

    Great pH buffer, add DROPS instead of MILLILITERS to achieve desired ph readings … elevates D.O levels .. to assist with rapid & healthy root growth.

    This stuff is by far the best O2 out there. Way better than blowers and doesn't hurt the plants like hydrogen peroxide. Makes a big difference with yield too! Great product! Thanks DO!
