I trimmed off a lot of the lower branches and the biggest leaves on top that were shading the little lower leaves. Now it doesn't look so bushy and green, but hopefully this will produce more buds. Also did some topping. Will probably force the flowering phase next week sometime.

A little more pruning and the plant has been growing too. It's turning into a "Sea of Green" (or SOG), meaning that there's a layer of leaves at the top of the plant closest to the lights and lower leaves pruned off. This maximizes the amount of light going to the plant's leaves, since there aren't any lower leaves that would be in the shade. Had to raise up the lights a bit today, since the plant has been getting taller. It's around 16" tall now.

Here are today's pictures:

Dude, I like what you're doing here. Subbed. This is very interesting. So you use that fogger thingamajig instead of a drip or spray? Interesting. The thought of trying that route has occurred to me, but I was always hesitant. It looks like it's working pretty great for you. I'll be checking this out.

You're micro-system is very cool. Only thing I would add? An easy add that will increase the size of your plant significantly? Get another air pump. Get two. Make it so that it's a swirling cauldron of oxygen bubbles in there. The cost of two more pumps and stones and the added power use is worth it. If it looks like a ridiculous swirl of bubbles in your res, your plants will react with ridiculous growth and speed.

That's kind of a harsh trim job, but you did it correctly in my opinion. I did a similar chop job on an OG I did earlier and it looked just like that only a little taller. The extra light and energy to the tops is worth the sacrifice.

Thanks, man. I was hoping someone would comment on my grow. Yeah, the ultrasonic fogger works great for me! It doesn't need a timer like a sprayer system does, which simplifies things a lot. One fogger unit is enough to completely fill the air space in the res. There are 2 minor downsides to using one: 1) It sterilizes the water. So don't use nutrients that contain live microbes. I use AN Voodoo Juice, but don't put it in the res, I drip it into the net basket at the top, using an eye dropper. 2) The fogger heats up the res water a bit, up to around 75-80 degrees in my tub. So the water can't hold as much air bubbles. But I believe that the fogger more than makes up the difference in oxygen feeding to the roots.

I will definitely take your advice and add at least one more air stone. That's a very good idea, especially since my res water is a bit warm. Thanks.

Thanks. I was scared at first that I chopped off too much, but the leaves grow surprisingly fast. I never did this before. Probably should have done some topping earlier, but I'm still learning. Probably will begin the flowering phase tomorrow. The plant's over a month old now.

I see, the fog is oxygenated and a good portion of the roots need to be exposed to air to absorb it. Cool. Maybe you should keep your bubbling where you have it then? But if you have the room for it, I'm sure another airstone in there WILL NOT hurt.

You just switched to flowering, right? I wanna see how they do in the more demanding grow phase. Looking good. Will stay tuned.

A month? That sounds about right. Yes, I always go through that after a severe prune job. Like, "Lordy look how skinny and naked they look now." But every time, chopping just seems to anger the plants and they grow even harder... and you gotta chop again next week.

Though you missed your chance to top them, aggressively removing the lower growth will def help in the end.

Yes, a good portion of the root system is above water and they divide into fine little hairs. I'll take a picture this weekend when I get around to changing the water. That's when I'll finally switch to the flowering phase.

I did add a second air stone today, so there are a lot more bubbles in the water. Nice tip. I think it will help a lot. I don't know if it's my imagination, but the plant seemed to drink a lot of water afterwards.

When I do change the water this weekend, I'm thinking of pulling the whole plant out of the res, lid and all, and putting it in a temporary bucket of plain water while I wash out the res to get out all of the sediment. I'm a little bit worried about damaging the roots when I pick it up, though. I'll drain out as much water as I can first, so they won't be so heavy. Any opinion on that?

Letting them sit in the plain water while you wash out the tub is an excellent choice. I would make sure there's a bubbler running in that temporary soak water. Letting them sit in oxygenated water will act as a flush and your plants will love you for it. I wouldn't be too worried if you damage a root strand here or there. When handling, a little damage is always expected, but the roots are a lot stronger than you might think. At the end of my last grow, I practically needed a hack saw to cut through the main root column to get it out of my tub.

Great to hear dude! Hey, I just read through your latest grow journal and saw the massive root system that you got coming out of those 6" net pots. Looked like a blonde girl's long hair combed out and hanging down. Mine aren't that thick coming out of the pot yet, but they're almost filling the res, which is a 10 gallon Rubbermaid Roughneck tote. I'll post a pic this weekend. Just remember for reference that my net pot is only about 3" in diameter.

By your root pics, it appears that you were picking up an entire plant, roots and all, out of the water. Now I'm not worried that my whole root mass will snap off at the bottom of the pot when I pick it up.

One question I have: How do you conceal the noise of that strong air pump. I had bought one of those by accident and when I tried it out, it sounded like a little jack hammer (slight exaggeration).

One request: Can you post an explanation of the design of your system, even if it's simply a photo of a hand-drawn diagram? I'm only on my second grow, so I have a lot to learn. Looks like you have a water chiller outside your box and an external water tank?

whoa, nice follow-up. I really enjoy sharing as much info as I can. That's a big part of the reason I finally started posting at RIU.

Here's a funny story: When i was first getting started, I actually used to suspend the plants on their platform by four light yoyo's while I pulled that massive tub out manually, having to disconnect all the hoses (there weren't as many back then, but it was still a bitch) to wash out the tub. This was not practical with plants this size so I knew I had to think of an alternative quickly. My final solution was a tub re-design where I could just lift the lid, pump the old water out, and leave tub, plants and all stationary. This is the best way to eliminate any shock during flush/water change time. I also realized it's impossible to take the plants out after I started getting into training. there are these shelf clips running all along the sides and back of my cabinet which I use to tie down angry branches. As for cleaning out the tub, I run fresh water for 30-45 mins between each water change and that serves to clean out all the pipes and roots automatically. Automation is my thing. Great for stoners.

I would recommend getting a small pump, a free power head, not one of those intended to stay put with suction cups, and use that to suck the water out of your tub while leaving your plant and its roots right where they are. Taking it out and letting them rinse in a second bucket is okay for now, but you got a plant quickly gaining size and already filling a ten gal bin with roots. I wouldn't recommend taking the plant out when the roots are really heavy in the bottom of the res.

The air pump. It's loud as hell. I know. I mentioned it in an earlier post. How do I conceal it? I don't. I have it sitting by its rubber feet on a cinder block. This minimizes the noise from the vibration, but it is still pretty loud. But with the root development and speed and power of budding that has resulted, worth the noise and then some.

I can def show you a diagram of my setup. That would be kind of fun to make and waste more time. Yeah, external res of plain water set to a pump on a float switch inside the main res. Float switches are NOT expensive online and when you set up an auto-topping tank, you will wonder how you ever lived without it. The chiller, on the other hand, is not so inexpensive. It was something I had my eye on for some time, but struggled with frozen water bottles trying to avoid spending the 300.00. It was painful on the wallet, but when it arrived and I hooked it up, all the pain vanished.

I'll post a simple diagram in my journal as soon as I can.

Oh, Edit. I realize you don't have the robust circulation of the water from a sprayer system, but if your tub isn't getting too mucked up, it should be okay for you to drain the water with a small pump like the one i described, refill it with fresh water, and just let them soak in that while you sort of wipe the sides and whatnot.

Wow, that's a lot of helpful advice already. I didn't realize that your system was so complex. The photos of the outside of the res made it look deceptively simple. The float switch and external tank for topping off the water automatically is sheer genius. If only I could find a way to automate pH adjustments, maybe I could leave my plant alone for a week and go on vacation. :-)

I actually do have a water pump that I used on my previous grow to make a hose-less sprinkler system:
[video=youtube;MZVYF7LCnAQ]http://www.youtube.com/watch?v=MZVYF7LCnAQ[/video]

But I never could figure out a good on/off timer schedule. It turned out that it wasn't the sprinkler that was at fault, but some asshole sold me a bottle of bogus nutrient solution over the internet. (Was supposed to be Advanced Nutrients Sensi Grow, but was clear, not brown like the real thing. Live and learn. Waste of 2 good seeds and 2 months of work.) Anyway, I might cannibalize the sprinkler for the pump someday, but right now I'm happy just dragging the res into my shower and opening the spigot.

Hey, I did lift out my plant with the lid still attached to the net pot, the whole thing together, and it wasn't a problem at all. My wife only told me to put slightly warm water in the other "temporary" tub so that it wouldn't shock the roots like cold tap water might. Anyway, the roots weren't as heavy as I thought they'd be so as long as I patiently let the water drain off them before lifting them all the way out. When I later took them out of the temporary tub, they left behind some crud that had been clinging to them, so that cleaned them off a bit.

I took a few pics of the roots today after changing the water and adding flowering nutes for the first time (Advanced Nutrients Sensi Bloom A&B). I'll post them later tonight. Right now I only have 4 gallons of water in the res, which seems to be ok as long as I check it every day. Not sure if that's best or if I should use more. Of course I also changed the lighting schedule to 12/12 and replaced the fluorescent tubes with ones that are 3000 K. I hope that does the trick. I'm really eager to see some flowers blooming now!

Dude, that blue sprinkler tub in the video looks great. Why aren't you using that? Or are you using it for something else? Your pvc/sprinkler rig is more complex than mine. I have the cloner tips, while you have the spinners. Looks really cool. You could totally grow monsters in that.

As promised, here are the pics I took of my roots today:

These are some thick, gnarly roots! Kind of remind me of horseradish. Remember, the part that stays above water gets nutrient-enriched fog. Not sure why they look like this, though.

I just wanted to try something different because my first grow was a flop. So I decided to do something with a fogger. I think that fog is maybe even better, because the water droplets are microscopic and easier for the roots to absorb (so I've read). I might even try propping more root above the water's surface for a while to see if it's better. Anyway, less stuff in the tank to get tangled in the roots than when I used the sprinkler, and no special timer is involved. The only timer I use turns stuff on & off along with the lights. I keep the bubbles going all night, but the fogger & fans get turned off. I don't believe that the plant feeds when the lights are out.

Yeah, you got the 'radish roots' alright. Looking very healthy. It depends on the strain from what I've seen. Some plants grow a column of fewer but much thicker cords, giving you that radish effect. Other plants grow many, many smaller strands (like mine) giving it the blonde chick effect. Anyways, what you really gotta look at is that root mass developing in the body of your res, sir. It looks pretty big already and it's just gonna fill up that bin in a hurry during flowering fyi. What you got here is a plant responding well to mostly dwc, tho. I'm sure the mist or 'smoke' nutrients hitting that exposed root column of yours is helping, but she's drinking mostly from the pool. when she starts sizing up during the first aggressive stages of flower, I can see those roots filling to the point where they mold themselves into the shape of that tote. Yeah, you're gonna have problems picking that thing up in the near future, bruthah.

What? How was your first grow a flop, bro? That tote you designed looks top notch. Can I have it? Lol. No, seriously what went wrong?

I see about your fogger theory and you're probably right, but it looks to me like that bitch is spreading her nets in the pool, yo. I want to see a picture with so many bubbles in there that it looks like the roots are boiling. Just keep putting more air in that water until you say to yourself, "Man, that looks like a ridiculous amount of bubbles." --and see what happens. If you lower your water level like you're thinkin' about trying, make the water/oxygen ratio even greater on the oxygen side by making it boil and keep hitting it with the fogger, I bet you'll have results worth noting.

Edit:

BTW, If i were a superhero I would be Oxygen Man. Straight up.

The tote & sprinkler were good, but the real problem was bogus nutrient. That's what killed my 2 plants, not the other stuff. But I thought the fogger would work even better than a sprinkler for the reasons I described above. If the roots in the res bulk up and rise out of the water, then there will be more of them exposed to the fog. I want to experiment with that. My air pump is about maxed out and this grow cabinet is in our bedroom closet where my wife has to hear it while trying to sleep. So I can't add more air than I have making bubbles. I think that forces me to trust in the fog. I'm not planning to lower the water level, just considering whether to prop up the roots higher so more of them will be exposed to fog. Eager to see what happens.
