So I come home today and BAM one plant is wilting in my aero system, weird - it had been doing great the day before. They've only been in there a week and a half and most are about 1' tall and incredibly bushy. Then I look at the roots and it's roots are a light colored brown, all of...

I'm putting this here because it seems to be an uncommon method. Has anyone tried a foliar rooting hormone? I see there's a couple of approved brands for this particular use. I ask because the last clones of gg #4 I had took three weeks to get like half inch roots and yellowed up on me...

Hopefully the calcium citrate is viable. The problem with calcium nitrate is to remove the ammonium one must turn it into insoluble ammonium ferric chromate, which has no known use (as far as I know) in and of itself so it's kind of wasteful. The potential problem with calcium acetate...

No doubt that is an issue, but I can't run an orp controller if it's going to dump 20ppm total chlorine into my reservoir either because the ammonium and chlorine complex and lower orp.

There's an entire study named for ammonium reducing available chlorine. I found a synthesis for ammonium ferric chromate which is insoluble. It could be made with just the calnit in solution and the precipitated red powder filtered out. I just can't read German to see the original text...

The trace of chlorine would immediately complex with the ammonia that was there. Drinking water standards, albeit a bit arbitrary line up with the only study I've read in terms of phytotoxicity for chlorine in plants watered via root system (not overhead) in terms of a 4ppm limit. ammonia...

It is the only ammonium I have present, but at 1.0EC I end up with about 5ppm. After it complexes with chlorine I end up with 5-15ppm cl used up by the ammonium. The ammonium in dynagrow is so high I couldn't get a single ppm free chlorine and it smelled like a pool lol. Uv, ozone, etc...

Oops, I meant @churchhaze

Does anyone know of alternative sources to calcium than calcium nitrate that are soluble in an a-b type concentrate stock solution? I would like a chemical something that is unreactive with chlorine, as I'm trying to create a fertilizer that is unreactive with chlorine to maintain a higher ORP...

Help? Lol I was just showing that the zinc hasn't killed it and that it's fine to diy nutes that high in zinc. That is, until I realized this morning there's almost no nutes in the water. It appears my sample pot has some salt buildup and is registering higher conductivity than the...

You're right about the mirrors I think. Nonetheless, I believe you're on your way to an episode of beyond scared straight. Do you really think you can perpetually keep this a secret? You don't think your parents at some time or another are going to smell you trimming, smoking, or growing and...

Here's a test clone I'm running while waiting for others to fully root in bubbler/ensure my self brewed nutes are good. Trying to keep at least links to relevant info here...

Here's the clone on the day three of its transplant into the aero setup. It's running 15 on 15 off but I think I'll switch to 45 on 15 off. It seems to be wilting a little bit due to the small root system and large leaf mass. This wasn't an issue in the bubbler as long as the stem was...

For all the work, time, and money why don't you just stick to growing peppers and buy the weed? I'm all game for the scientific discussion but I hope your dad beats the stupid out of you for real. Albeit again... LEDs produce more light with less heat than anything else, you must have some...

Or add extra parabolic mirrors on the side which I'm assuming that the light source is more than two focal points away and so it will try to focus the light so it must be far enough away from the plants so it doesn't make a hot spot. Not ideal but better than light shining on the floor. Cost...

I believe a parabolic reflector greater than 2 focal points will concentrate the extra light. With a thicker glass such as you're talking about in front of the lens some refraction will come into play as jade mentioned. In that type of lens the light comes from the source and is refracted...

Edit to add: I was being rude because I believed you were saying parabolic mirrors will absorb some of the light in the same way a standard mirror would. This isn't always the case with any mirror/material. I believe the equation is: n1*sin(incident angle) = n2*sin(refractive angle) However...

I apologize for being rude, and you're correct about the headlight being sealed. However I believe that the heat capacity of the thin plastic is so low that it will maintain the temperature of the ambient air and not cool to the point of condensation. If I'm wrong, then applying a spray foam...

Please, if you're not knowledgeable behind the science of what you say then don't contribute anecdotal evidence. In order for light to be fully reflected the angle of incidence must be greater than the critical angle. A parabolic mirror is the only real practical light solution. I...

All my water is ro and uv filtered. The reason I bumped up calmag was because using dynagrow I had to supplement it so I bumped it up to be equivalent. So far so good. It's 15on 15off right now, still a little droopy from the small root system. You can take huge Cuttings in a bubble cloner...
