Okay so I'm a first-timer. Growing some AK-47 and some White Widow. My setup is a basic DWC bubbler system. 25-gallon bin with a tray with holes cut in it for net pots, two airstones, 600 watt Mars Hydro LED light, 6" inline fan with filter (my place is dusty and mold is present somewhere), 4" exhaust fan with filter, 24 deep x 48 wide x 60 tall stealth tent. I utilize the Lucas formula (5ml per 10l) of General Hydroponics nutes, add one tablet of CO2 to the res. weekly, maintain pH at around 5.8-6.0. I also use 29% hydropero, hydroguard, and complezym.
That all said...I'm struggling. I'm on my third attempt. My plants have been contracting pythium and dying within their first few weeks. I've done my reading, and I've come to understand that the source of the pythium is the water supply. I'm staring at my latest attempt, and they're wilting noticeably. I use rockwool cubes, pack them in, no light gets into the reservoir, I have the temperature of the water maintained usually around 68-71F. I don't really have any means of artificially lowering the temperature. I simply opted to spraypaint the outside of the bin glossy white, which has done plenty enough to keep the temperature in check. I know it's pythium because I'm seeing browning in the roots. Unfortunately, I was making a novice error and allowing the bubbles to splash water up into the cubes. As a result, the pythium is in the rockwool cubes. I'm certain they're doomed, and I'm about to pitch them.
Now, my question is... am what I considering doing for my next attempt going to be sufficient for sterilizing the water of pythium? My plan is:
After emptying res, splash boiling water onto the interior walls, constantly filling the res with boiling water as well to keep the water temp at least above 200F.
After emptying, clean with 1 parts bleach to 10 parts water, scrub with soft sponge
Rinse, clean again
Rinse
Boil airstones and air tubes, and/or soak them in hydropero
Now for the water to be added: Boil water before pouring into reservoir
Once to proper water-line, cover bin, wait for water to return to room temp
Once water is room temperature, add 60ml of hydropero
Leave h2o2-treated water to sit for 24-48 hours
Add 12ml/gallon of hydroguard (bacillus A.)
Add 60ml of Complezym
Add Lucas-formula-measured nutes
Add Co2 tablet
Adjust pH down to 5.5
Add plants, turn on bubblers to low power so they don't splash water up into the cubes
I'm down to my last three seeds. If this fails, I'm SOL. All I need is just one harvest to sell to get another batch of seeds and to pay my rent for a couple months. If anyone has any suggestions on anything else I could do that won't cost $50+ (I've strained my resources to their absolute limits) to prevent another $%&#ing pythium infection, please let me know, because I am at my wits' end, here.
For example, could I get a UV sterilizing light and expose the water to it overnight to pre-clean the water?
