Dave's Dual Area 51 Grow

[The Gator]

Hopefully she pulls through. Seems like you have hit every possible scenario in this grow. I think your adapting to the changing situations well though, keep it up! hope everything gets better.

 

[foreverflyhi]

Good luck on fixing the problems, sounds like your on top of it, live and learn.

As for the light mover, thiss is my second scrog with it, as of now here it is with one 190 in a 2x3.5x5' on a light mover, moving about 1.5ft each side from the middle,

I havent flowered this scrog yet, but when i do ill probley add extra light.

Interesting setup there, Yoda. It looks like you have 2 nets for your SCROG. Why 2 nets? I never saw that before.

OK, it also looks like you'll be using one light for 2 plants. I assume that the smaller plants are only there temporarily? Looking good. I might want to try that. Do you have a thread for this grow so that I can follow it?

And do you have any info on the light mover that you're using? That might be perfect for my closet.

So far it's too early to tell whether the h2o2 fixed the problem or not. No signs yet. It's possible that I went too far and damaged the roots. I saw lots of little fine roots floating in the water that detached from the root ball last night after rinsing them with plain water, so it must have been a little traumatic at least. I think we'll see pretty soon if it was too much.

The lesson in all this is to keep light out of your res! The less it's exposed to light, the less chance of getting root rot.

Today I added Voodoo Juice to the res water. Voodoo Juice promotes root growth.

Eh have a couple journals, but non aactive currently, do try to post pics every now and then.
Yes small plants are moving into a bigger pot/diffrent room.
And yes two screens, these sativas stretch like crazy, two nets will do the job on holding them up with more even canopy, i think captain has a journal with two nets.
Light rail 3.5 newest edition i believe. Stay away from old ones unless u have motor skills.

Thanks for the Light Rail link! Looks like a good American company.

Looks like you have to screw a 2x4 to the ceiling to mount the Light Rail onto. Is that how to do it? I couldn't find any instructions on the web site.

Dead, rotten roots:

Lusinda barely ate or drank anything for a whole week, so I figured she’d die if I didn’t do something drastic. So I took a close look at her roots and saw how gross they became.

I think what might have happened is that the hydrogen peroxide wasn’t diluted enough when I sprayed it into the root ball last week and I didn’t rinse it out right away. So yesterday I ripped out a bunch of the dead roots and rinsed out the remaining root ball about 5-6 times until the water stayed fairly clear. Then I added some Voodoo Juice to the other nutes again to promote root growth.

Lusinda’s lower leaves especially took a beating…

but her buds actually grew a little:

Another problem is that Lusinda’s main branches swelled around the strings that I used for training her:

Now I know about those soft bendable ties for plants. I’ll use them next time for LST.

One of Tabitha’s tops grew up to the lights again. I’ll probably need to clip it off.

 

[The Gator]

That picture you took of the branch swelling is probably one of the most interesting things i've seen. Is this something that can occur often or does this occur in certain circumstances?

Have you considered just supercropping the tall branch rather than clipping it right off? Can't be any worse than clipping it off, and would probably save the branch.

Hope it all turns out well, D! That Tahoe OG is a leggy thing, isn't it?

I just bent it over, so it's still there. The branch kinked, but I think that top will survive.

That Tahoe doesn't know when to stop growing! Sheez!

It's not good and shouldn't happen. I should have used something else to tie around the plants without making a knot like I did with that string. Someone told me about soft garden ties that are made for this and I'll start using them now. I never knew this would be a problem until I saw these branches.

RIP Lusinda

Had to put her out of her misery the other day. She was still not taking anything in through her roots and was dying a slow death. Here’s what she looked like:

Her lower leaves were being canabalized.

I harvested the little buds for making canna cookies. I actually got a nice rush from smoking the finger hash from this. Here’s what she looked like after plucking off the fan leaves:

I like the result of topping 3 times early on. I got 6 main branches that way.
These are the garden ties that I’ll use next time:

That really sucks, Dave. My condolences. Hope the cookies turn out good!

Root rot was the main culprit. Then I must have been too aggressive killing the algae with h2o2 that was a bit too strong. Next time I'll try to prevent root rot by sealing up the little cracks that let light in the res. I might even use a tri-meter that hangs in the res all the time, so that I won't have to open it up as often.

I think that the string-ulation didn't help at all, either, so the wire ties will prevent that from happening again. Someone should have hollered at me about tying string around those branches. I was never an indoor gardener before and didn't know the dangers of doing that.

Note: I was surprised how stinky the plant was when I cut it up, even the bare branches gave off a lot of odor. LSD is one stinky strain! And I like it that way!!!

in my experience growing mushrooms, peracetic acid was
much more effective at sanitizing than hydrogen peroxide by
itself. it wasn't any more harmful than h2o2 as long as proper
precautions are taken (ventilation mostly). it can also be made
at home by mixing 3% hydrogen peroxide and 5% acetic acid
(white vinegar) in a 1:1 ratio.

The United States Environmental Protection Agency first registered peracetic acid as an antimicrobial in 1985 for indoor use on hard surfaces. Use sites include agricultural premises, food establishments, medical facilities, and home bathrooms. Peracetic acid is also registered for use in dairy/cheese processing plants, on food processing equipment, and in pasteurizers in breweries, wineries, and beverage plants.[5] It is also applied for the disinfection of medical supplies, to prevent bio film formation in pulp industries, and as a water purifier and disinfectant. Peracetic acid can be used as a cooling tower water disinfect, where it prevents bio film formation and effectively controls Legionella bacteria. A trade name for peracetic acid as an antimicrobial is Nu-Cidex

Thanks for the tip, Indie! That's cool information that I never heard about before. I haven't read the Wikipedia article yet, but I take it that this stuff is safe for contact with plants? I mean it won't burn the roots, will it? I think that the h2o2 that I sprayed on Lusinda's roots was only 6% h2o2 by itself and that definitely hurt them. So that's why I worry about it.

here's what i dug up on using it in a hydroponic system,
peroxyacetic acid is a longer name for the same stuff.

ABSTRACT
The goal of this research was to evaluate the effect of different doses of peroxyacetic acid on the productivity of watercress (Nasturtium officinale R. Br.) cultivated hydroponically using a constant nutritive solution. Green chemistry in protected horticulture seeks compatibility with the environment through the creation of biodegradable byproducts. In hydroponics, appropriate doses of peroxyacetic mixtures deliver these byproducts while also oxygenating the roots. Watercress producers who recirculate the nutritive solution can use these mixtures in order to increase oxygenation in the hydroponic system. The experiment took place between August and December 2009, beginning with the planting of the watercress seeds and concluding with the completion of the sensory panels. A completely random design was used, including three treatments and four repetitions, with applications of 0, 20 and 40 mg L-1 of the peroxyacetic mixture. Measured variables were growth (plant height, leaf length and stem diameter), yield (weight per plant and dry matter) and organoleptic quality (color and sensory panel). The application of 40 mg L-1 of the peroxyacetic mixture had a greater effect on the growth and development of the plants, which reached an average height of 29.3 cm, stem diameter of 3.3 mm and leaf length of 7.6 cm, whereas the control group reached an average height of only 20.2 cm, stem diameter of 1.9 mm and leaf length of 5.7 cm. The application of the peroxyacetic mixtures resulted in an improvement in growth parameters as well as in yield. Individual weights achieved using the 40 mg L-1 dose were 1.3 g plant-1 in the control group and 3.4 g plant-1 in the experimental group (62% yield increase). Sensory analysis revealed no differences in organoleptic quality.

Peracetic acid (PAA) has potential as a disinfectant of low environmental impact for glasshouse hydroponic systems and other horticultural applications, but can have phytotoxic effects. This study examined the physiological effects of PAA when applied hydroponically to tomato plants. Plants treated with 0.5-5 microgams ml PAA over several weeks exhibited a reduction in size of all vegetative organs. During the first 2 h of PAA treatment, plants also exhibited a transient wilting, with increased stomatal resistance, and reductions in transpiration and CO2 assimilation. The toxicity of PAA to roots was apparent from increased leakage of root electrolytes, reduced oxygen consumption, death of root tips, and collapse of the internal tissues. The shrivelling of PAA-treated roots resulted from loss of water to the shoot in the transpiration stream, as the effect could be eliminated by removal of the shoot and sealing of the cut stump. HgCl2, a reagent known to reduce the hydraulic conductivity of root systems, caused the same root shrivelling effects as PAA. Long-term growth of PAA-treated plants was dependent upon the replacement of taproot systems by adventitious roots, which, initially at least, displayed greater tolerance of PAA. In aqueous solution, PAA exists in equilibrium with H2O2 and acetic acid, both of which were individually toxic, but acetic acid exhibited a syndrome of effects distinct from those of PAA, while the effects of H2O2 paralleled those of PAA more closely, suggesting that oxidative rather than acidic mechanisms were primarily responsible for the phytotoxicity of PAA solutions.

those two articles contradict each other, lol. IMO it's worth a shot
because the hydrogen peroxide didn't work and it damaged the
plant roots, striking out on both counts. if it damages the roots but
works that's still a step in the right direction.

and here's a pdf on it as well.

Interesting... Obviously, concentration matters. Maybe the article that mentioned plant damage used too high of a concentration. I would guess that it's no more harmful than h2o2 when used at about the same concentration, but I wouldn't bet an expensive plant on it, not without more confirmation.

h2o2 usually does work against root rot. I've used it to clear it up before. But thanks a lot for this info. I'll keep it in mind and maybe make some to use for sterilizing my equipment.
