no wucking furries, mate :)

Try other hydro shops or foodservice supply houses. Hydro shops should have 50%. 35% is common in foodservice as a steriliser.

Clonex is not a pathogen inhibitor. Left long enough (long enough for the chlorine in the tap water to flash off, a few days), pythium & fusarium would colonise your aerocloner soln, no freaking doubt. Regular application of H2O2 is the trick to keep it all clean, aerocloner or DWC.

A 1000HPS in a cooltube should raise the air temp passing it by about 6C i.e. 20C in, 26C out. If you pump air through the cooltube faster, the output temp will come closer to the input temp. If your output air is more than about 6C warmer than the intake air, you may have too long a duct, not...

I like reliable high yielders, but there's some I've run across which are flavourless or otherwise deficient. I didn't much like Skunk #1, for example. makes a ton of dope but you really get tired of smoking it. The best plant is a compromise of yield, high, mould/fungus resistance and nice...

Simply Hydro maintains a good comparative reference here. Good move, flood (aka e&f) systems are cheap and dead-nuts reliable. Your watering interval depends on how much water your medium of choice will hold. Rockwool is HIGHLY absorbent, so you'll water that rather infrequently, 1x/day in...

Thanks for that. :) Cracked my first beans in 1979. :) Whether that's true or not, if the two plants are sharing the same reservoir, you'd never measure a difference in the rez per se, particularly with airstones constantly agitating and mixing the rez soln about. If you could stick a pH...

Simply Hydro maintains a nice reference of different sorts of watering systems. Look here. Flood (aka ebb & flow) systems are the simplest, cheapest and most noob-friendly sort of watering systems.

Hygrozyme is made from enzymatic proteins. It is supposed to attack and break down dead organic matter, same as H2O2. However, Hygrozyme isn't always effective and it is incompatible with H2O2. H2O2 will break down the proteins in Hygrozyme just as it breaks down any other dead organic matter it...

Floods (aka ebb & flow) are the simplest hydro systems bar none and really the most practical way to water a SoG op. Flood systems are dead simple to set up and maintain, can't clog with nute salts and are very cheap to boot. Simply Hydro maintains a great comparative reference here.

That's unlikely to be the problem. Root rot is generally caused by overwatering, which drives all the oxygen out of the medium, allowing anaerobic pathogens to take hold and damage roots. H2O2 is the solution. Apply 50% grade H2O2 @ 1ml/L or 35% H2O2 @ 1.7ml/L to your nute tank every 3-4 days...

Dump your tank, mix up new sauce. Small expense compared to the problems you may have later down the track. The point is that vascular plants have no need for sugars. If there was a Great Molasses Lake somewhere, there would be plants evolved to grow on its shores and suck up the sugar...

Ya know what? You're dead-nuts right, that's the most important thing out of any of the threads. I don't even want to admit how long it took me to work out how to properly water RW cubes in cloning. I did a whole thread on cloning in rockwool cubes, pivoting on that very idea of 'damp, not WET...

well done, looks yummy.:) The 'solar lighter' is the dog's bollocks. I TRULY ♥ that shot. :)

O2 to the roots is the name of the game. It's the main reason hydroponics works better than soil. DWC is great because it gets the media out of the way, improving root contact with highly oxygenated nute soln. As long as you plan for DWC's Achilles' heel of sensitivity to power outages, it can...

If you're not using it already, dose your bubblers with H2O2, 50% grade @ 1ml/litre, every 3-4 days. Stops pathogens dead and releases O2 directly in the rootzone when it is breaking down organic matter. If you can't get 50%, use 35% 'food grade' (found at foodservice suppliers for sterilising...

Yep, low water temps probably saved your bacon. Water readily loses dissolved O2 at higher temps. Almost impossible to keep water oxygenated at or above 27C. A UPS for a computer, perhaps upgraded by adding a larger battery, is a veddy veddy good thing for bubbler fans.

Won't SOMEBODY think of the tits? :lol: ...but if you think that was fucking tits, you ought to see this. ;) Really? How do you get the trays to flood when they're stuck to the ceiling like that? :lol: Gravity sucks, you know. ;) Thanks. :)...

No. Flushing means pouring a large volume of plain water (pH adjust to 5.8 ) through the medium, usually to remove excess nutrient in the case of accidentally overdosing.

otta fix it. :)
