You can see these ones air pruned directly in RR for a few days with very rapid growth, fast as can be. The rate is maintained when submerged as the roots don't experience any period of reduced access to air. Those pruned tips are already exposed to flow and ready to explode into it. I just to...

Prune the tap root. Air prune or snap it off when you see it. It won't get damp off. This seedling is ready to be submerged and will not exhibit slowed growth from it. The explosive lateral root growth helps them emerge and break surface even sooner, so snip it the second you see it or set it...

Yeah, it's a long post, but it's a complex topic and there seems to be a few different trains of thought that don't seem to quite resolve in practice, and are just left open ended, for those with more experience to simply know. Why does my "P" seem "kind of high", if in fact I am adhering ot...

That's because the tubing is a resistance to air flow, and so the more tubing you have the greater the resistance to airflow. It then stands to reason, if you have all different lengths of tubing, you will have all different resistances to airflow, and the air will seek the path of least...

Dead forum.

Right so I played around with the nutrient calculator a little more just to see what lower doses of my maxi mix looks like, more in line with how it's being used. It really seems to shift the numbers around a fair bit. So yeah I wonder if it's better to hold it at a specific EC like 1.2 and a...

Hi, I'm not sure if I'm screwing myself here as my original simple soup gets more elaborate and it's my first grow. I'm using 1:6 grams of maxi gro and bloom respectively, pre mixed at that ratio and I just bring the TDS up to what the plants are using, and maintain it at whatever rate...

There's a wave floating around of people saying the tea doesn't multiply fungus unless it's on the roots. an's whore erich schmidt video on youtube and maybe another tea guy who sells his brew may have mentioned it as the correct way to use mycorrizae and Heizenburg at rollitup adapted his...

Same experience as others mentioned here. Citric acid as pH down in DWC = completely unstable. Even while adjusting it I found it was susceptible to mad swings... "bounce". I read it's a source of carbon which feeds bacteria, so that's not good for stability, and that its' also a "Weak" acid...

That looks like an interesting product, probably because like some of the other ceramic "micro bubble" stones, that are so damned expensive, they're likely subject to a better manufacturing method, producing a more uniform product, not only across the part itself but the manufacturing spread as...

mmhm.... yeh. I went with the GH dual diaphragm pump because it was supposed to be quiet..... it isn't really. But the piston based pumps are not known for quiet operation at all. Valves and pushrods are just going to be noisier. I had to build a housing just to muffle the noise from the GH...

Thanks for the blender spam. Back to the subject at hand though. I wonder if the airstone also might be too large for the pump capability. These chinese manufacturers and importers, which is all of them it seems, rarely if ever offer proper specifications. How the hell can you properly match...

They're all roughly the same because they're all setup identically. Same line lengths, same amount of water, and from the same common manifold which is not like the stock abhorrent contraption. I'm running 2X GH dual diaphragm pumps, feeding both of the outputs from each one into a glass jar...

Hi, I have a number of buckets in DWC, two air pumps, and one to two large cylindrical air stones per bucket that are all fed from common manifolds, one per pump. There is a fair bit of overpressure from the manifolds and all the line are the same length with the same water levels, so back...

You have to ask yourself how a clown like that gets that kind of free advertising. Cons like him know how to work the levers, and we'd be mindful to ensure their little courses don't become mandatory under any circumstances.

Would have to know more specifics about your setup. Safe to assume from your post that you're growing in soil or other medium, not dwc? So if you're talking about the first kind of flush, where your goal is to prevent a toxic built up, there are different ways to go about it from what I know...

What are you talking about man, your post doesn't agree with his at all. He said you can get an expensive brand name tent cheaper if you get it used (and probably damaged). You're saying you got a brand name no-name tent for 70 dollars. If it's a 5X10 tent that retailed for 260 there's no way...

Oh for sure. Wouldn't it be so great if I could not only go to a brick and mortar to see the products, but actually one that demonstrated them such that you could make a truly educated decision, and even stood behind their products. Alas, t'aint the reality du jour at all. Maybe some of them...

Yeah well, "fairly quiet" means a lot of nothing, no offense. We really should be pressuring industry to give us quantifiable information in that regard since most of us don't get to test them and stealth is often a huge factor. I was originally looking into that type of pump given their...

All the same, it deviates from the intent of the analogy, which is that you have to address the source of the issue, rather than the symptoms of it. That's always the effective and optimal route. If you just patched bandages around a knife, left the knife in place and called it fixed, it will...
