Dozens on #roulette are very misunderstood, Simply betting any random dozen will get you the same results as using a strategy.

 Understanding dozens nature and how they don't chop no where near as much as a 1/1 is the key to winning on dozens constantly, the cons are you'll never be a millionaire from it … good luck is a thing of the past.  Test it all here on our free roulette  trigger tracker tool https://gamble-galaxy.com/tv10/triggers.html

Flood and drain, air stones waste of time?

Hi guys,

I am running flood and drain with 100L (26 gallon) reseviors. I have airstones in all my reseviors. But reading up recently there is a lot of debate about wether this is a good idea (introduces airborne pathogrens and other nasties). Should I stop doing this? Is a move to small recirculating pumps the best alternative? Do I even need to worry? Will the constant flooding and drain be enough to keep the reseviors well mixed and airated?

Thanks for responses.

How concentrated to make Nutrient Solution in my 13 Gallon RDWC Reservoir for One big Plant?

I am modifying my Power Grower RDWC systems to have a 13 Gallon Reservoir. And in general my tendency has been to make my PPM stronger then what they actually consume nutrient wise! I have done this because they don't seem to burn and because they can consume the whole entirely of the reservoir in one day at their peak flowering cycle. In Veg my plants can drink as high as 1400 PPM which seems crazy. But as soon as I flip the light cycle this drops to about 600-700. .5 conversion And I...

Is AISI-302 stainless steel good for the reservoir with nutrients?

I am wondering if AISI-302 stainless steel parts are suited for permantent contact with the nutrients? It is because I am thinking about using a non return valve which in the reservoir which has AISI-302 grade parts. I don't know how aggressive the nutrients are to metals and if this kind of stainless steel might bleed toxic stuff into the reservoir.... Any idea? April 22, 2019 at 04:01PM Read more about this fix

How to correct Rising pH/PPM runoff

Okay so this is my first run with Hydroponics. I have been running a top feed drip line system. I am running my girls in 6 inch rockwool cubes placed in 7 x 7 pots filled with hydroton. There almost 28 days into veg from seed. I've begun to notice a couple rust spots on my girls nothing too major. I figured starting a little nute burn. So I backed off the nutes a little. I've been keeping track of the runoff and two of my girls now" the ones that are showing the rust spots and a slight droop...
