East Asia: A Cultural, Social, and Political History

The best you can get!!!

From special brews to disinfecting roots. Nothing compares to this simple formula and nothing works better. I was skeptical and am kinda blown away with how well it worked. I almost trashed my plant and then figured I'd give Hydro guard a try. Definitively worth it!

after just a week and my DWC has perked up and this week it grew a foot i know its a veg week supposed to grow but it just seems so much healthier and happier with this little change added to my water every week

I'm new to Hydroponics, growing leafy greens in a NFT system and was amazed at how fast one unhappy plant can get root rot and spread it to the entire system AND how fast this stuff can turn things around. Talking less than 24 hrs to see noticeable improvements. Can't imagine not having this as part of my system.

This product was delivered on 3/13/23. If it is good for up to 2 years after the date on the bottle, that would mean I only have 5½ months of guaranteed results instead of the 6 months it’s guaranteed from after opening. From the hole in the top, it looks to me that this bottle might have already been returned once…

The media could not be loaded.  This really helped my rootsystem bounce back. I would definitely recommend using it for first time grower or experience grower because it really helped make a difference in my plants growth cycle.

Jan. 12, 2020 Update: this is a product for organic nutrients/organic supplements NOT SYNTHETIC nutrients. For those that need questions answered like me but didn't have any answered on these reviews, so here's mine. Does this work in a DWC HYDROPONIC system using synthetic nutrients such as General Hydroponic Performance Pack? No! Why? General Hydroponics nutrients are all synthetic. The do carry a organic series but come on, if your growing inn hydroponics, just stay away from organic nutrients. Do they work, some do but it's not with it. Growing in soil, use organic nutrients not synthetic. I recommended UC Roots for hydroponic systems, not hydrogaurd which is meant to break down organic compounds. You don't have organic compounds in synthetic nutrients, if you use this in DWC hydroponic systems, with synthetic nutrients, you'll kill your plants over time. I can't review on how this works in soil or with organic nutrients shop this is not a bad review or a negative comment. I didn't read what my buddy actually gave me cause cause it's sold in the same container, after the fact I realized it was something else, hydrogaurd. Just read the labels...I've read so much negative comments about how the dates are off or scratched off removed etc, I just ordered another bottleand it better be right! If it is I'll post a great review.Update: Can this be used with general hydroponics performance pack NOT organic? I'm seeing that this product is intended for organic nutrients, but what about none organic? Did I really waste my money? Or would I be able to get a refund or exchange it for a clear res or skunklabs use to make res clear and it was the best ever, but it's disappeared now. Any suggestions?

could not get rid of root rot, not with 34% h202, not with 15ppm of chlorine, change outs did not help. I had high chlorine levels in the system which did keep PH stable, but plants would not eat the rot was not effected just kept the water clean. I then added the last of the h202 I had left to neutralize the chlorine, and do what ever damage it could to the rot. about 24 hours after since there was plenty of work for the h202 to do it most likely had all turned into water\oxygen within the first 24 hours. I then without a change out added 2ml gallon of Hydroguard, then a about 1\2ml gallon every day after for about a week. The plants almost instantly started eating 30-40ppm per day, and the water was dropping again although I had clear indication that the rot was still there as the PH would drop 7-10 points first day then slowly got better maybe 5-6 points etc, but became very stable after several days only raising 1-2 points as it should if the plants are eating good. I think some have success with sterile and some with bacteria like Hydroguard.I found a product called sag fungicide its a different strain bacteria then Hydroguard, but the same species but extremely concentrated for a fair price i will be testing it when my HG runs out. UC roots the recommended product was not the right choice for me. as I don't know if I could have added enough to keep my system clean. also I have no light leaks I'm very experienced and knowledgeable I understand these things, also my chiller is oversized and rez is at 67 degrees. first time trying beneficial bacteria and I love it, it seems logical too its like putting 1 billion mosquito into a sealed room with idk couple 100 squirrel's lol they have no defense.

Quite good

Was required for my Asian Studies course. My course actually asked for the Pre-Modern East Asia (up to 1800) but since I know I'll be taking another course that continues the course content, I didn't want to pay $120 for the first volume and then another $120 for the second volume, especially since they have the same content.From what I've seen on the content so far, it's neatly organized and concise. Would recommend to other people who are interested in learning about East Asian history.
