Before we get all wound up about DO matters and the facts, do any of you have any idea exactly how much dissolved oxygen is really necessary in order to prevent low oxygen insults for canna rhizomes and beneficial microbes in hydroponic life support systems? By the way, testing water quality DO...

They say you need to keep track of your PH and PPM in DWC/RDWC grows and you got to buy these meters and test Ph and PPM in the res water. So, what brand Ph and PPM meters are popular and how much do these meters cost? Why can’t you just look at the plants and roots symptoms and just guess...

Oxygen (O2) is absolutely the most vital elemental nutrient needed continuously by all aerobic people, plants and microbes. To eliminate confusion, elemental oxygen (O2) is not air. Air is 4/5 elemental nitrogen gas. Air does contain a small amount of elemental O2 (1/5 by volume). More air...

Hydrogen peroxide (H2O2) is no doubt a great disinfectant and it's cheap. People have been disinfecting minor cuts and abrasions effectively for years with it. It's even used by hair dressers to bleach hair blond. Is the fungus the culprit that causes the roots to die and rot or is the fungus...

Didn't mean to stray. The post looked clearly like an advertisement to me and I was just wondering how much he charges for his product... that's all.

Question: If you pump 5 times more air with a giant air pump, will you get 5 times more oxygen and 5 times more nitrogen that a smaller air pump will deliver? Just wondering, if a little air is good, then a lot of air is better and air is 20% oxygen. So logically a giant air pump that pumps 5...

How much do you sell your home grown marijuana for... how much $ for 1/2 pound? Will you ship it to Louisiana? Need more information.

Your personal opinion please: What do you consider the optimal DO saturation that should be maintained in res water throughout the growing season in order to eliminate any low oxygen crisis like root suffocation, sick roots, dying roots and so on? I see you do a lot of testing. How do you...

Yes, air stones do have issues, but those stones are cheap and disposable too. Air stones make big bubbles, medium bubbles, tiny mini-bubbles, micro-bubbles, all sizes of gas bubbles. When the pores occlude they make no bubbles. Many growers seldom admit they have a problems with ambient air...

How did your O2Grow oxygenator work out for you now you have some experience and DO testing behind you? Did the O2 generator maintain DO Supersaturation continuously throughout months of the growing cycle as advertised? In your opinion is the cost worth the stealth, increase in DO Sat., better...

This is no challenge of wits at all, this is pure horticulture science and technology for profits and fun vs. "reading the leaves" so to speak, that's all this is. Great looking sticks, what do you sell 1/2 oz. of those buds for?

Well fatawa, even the least savvy, beginner DWC hobby growers very seldom has any problems with root rot and fungal infestations so they claim. Everyone hobbyist DWC pot grower knows that it’s really hard to suffocate Rhizomes in res water. Killing the roots really takes an exerted effort, gross...

BRAVO…Hey cannabeans you are definitely the brightest grower on this block for sure when it comes to oxygenation, how and why test dissolved oxygen in res water is so vitally important. Keep in mind that the vast majority of hobby growers do not know the difference between ambient and elemental...

Speaking of oxygen generators, electrolysis type... have you seen this one - http://keepfishalive.com/faq.php Same company makes O2Grow
