Acclimatization is required, and patience.

In my case no acclimatization was needed. Four month old and three weeks into flower with HPS 430 and ZERO problems.
I've gotten several cutting from others. They all use floro. So a 5 week old cutting under floro would need to adjust before full 400 CMH? Once again in my case not so. Under floros into CRM.
Because I may have gotten away with something I'd still follow Gator's advice "unless you're feeling lucky.........."

I love bubble cloners... Nice...

SS that simple bubble setup will root your girls nicely.

the macgyver of growing;)

very nice.:goodjob:


I can't take credit for it. Saw it on another forum when I was looking for DIY bubble cloners.

I'm using a thick aluminum pot because if I set it directly on the cement slab floor, it keeps the water nice and cool.

The clones in the bubbler are looking *great* today. They never missed a beat, actually.

According to some pics I saw, this bubbler produces long roots, so maybe they could go directly into hempy buckets? or use some intermediate container and grow them bigger first?

Coco retains water so well that I'm thinking there shouldn't be too much drama until the roots touch down.
 
Re: 420 Cannasumer Reports Competition - GrowLEDHydro 300w LED vs. 400w HID

well is ur little clone containers Hempy? is so how do their drain with the coco? if not maybe trying a little Hempy style cup and see how it drains with pure coco would help us understand why their should be hydroton in the res. but i would think its gonna sponge up and be water log


Why indeed? Coco coir cannot plug a drainage hole, only slow it down.

A 10 qt bucket of wet coir will keep a 32" flowering plant hydrated for a week!
Problem with a big bucket of coir is compression from the weight of water.
Perhaps a 50/50 homogenous mix; a matrix of hydroton, with coir filling the interstices. :idea:


The mini-hempy cups drain fine, but yeah, that much wet coco weighs nothing compared to 3 gallons. Thanks PG!

50/50 hydroton/coir sounds good, but that weekly watering sounds really good, lol.

Guess you can't have everything.

I haven't seen that product before, thanks!

Some of the growers here are using these "air pruning" pots and liking them.

ya check out that site theirs some good info.. read on the 4" rule.. i bet those little air pots would do great for clones or seedlings.

i my next grow i am thinking about doing a few coco air pots right next to my hempys to see how each one stacks up against each other.

but this company seems to know their stuff about air pruning

Hey SS, did that particular cloner use aluminum also? That looks like an anodized aluminum pot, is that correct?

The reason I ask is that aluminum toxicity is a known factor for stunting growth, particularly in roots:

Acid Soils and Aluminum Toxicity (PDF)

Hede Study said:
The primary response to aluminum stress occurs in the roots. Aluminum-injured roots are stubby and brittle. Root tips and lateral roots thicken and turn brown. The root system as a whole is affected, with many stubby lateral roots and no fine branching. Such roots are inefficient in absorbing nutrients and water.

Acidic water also tends to leach more Al into solution. Not really worried about the tin foil used as a light trap (if it's not in direct contact with the water), just the pot itself. Less of a problem if it's anodized, but still...not sure I'd take that chance.

Same reason folks don't use copper or brass fittings in hydro systems (Cu and Zn toxicity, respectively) - the plastics used are largely inert. Also why I never cook spaghetti sauce in a copper pot...
---

Lots of studies done on Al toxicity in relation to soil acidity also; for more reading:

Nutrient Deficiencies and Toxicities


Hydrofarm Site said:
Root stunting is characteristic of calcium deficiency, acidity, aluminum toxicity, and copper toxicity. Some species may also show it when boron deficient. The shortened roots become thickened, the laterals become stubby, peglike, and the whole system often discolors, brown or gray.

Aluminum Toxicity Tolerance

Dissolution of just a small fraction of the aluminum compounds in soils can result in serious Al toxicity to susceptible species.

A glance into aluminum toxicity and resistance in plants

Abstract

Aluminum toxicity is an important stress factor for plants in acidic environments. During the last decade considerable advances have been made in both techniques to assess the potentially toxic Al species in environmental samples, and knowledge about the mechanisms of Al toxicity and resistance in plants. After a short introduction on Al risk assessment, this review aims to give an up-to-date glance into current developments in the field of Al toxicity and resistance in plants, also providing sufficient background information for non-specialists in aluminum research. Special emphasis is paid to root growth and development as primary targets for Al toxicity. Mechanisms of exclusion of Al from sensitive root tips, as well as tolerance of high Al tissue levels are considered.

Again, this (toxicity sensitivity) is also species and strain dependent, and your anodized pots may be fine - but I prefer plastics myself.

Cheers,

Probably more typical than I was selectively remembering, Old Goat: no probs with common sense . I get real ugly leaves that came with the cutting, but I shouldn't blame the light.
I don't actually lose plants unless I let them dry out. My 400 was an instant hit with the floro starts it got: a few days to put out roots, then 12s. A few yellow leaves at the bottoms got plucked and wah la: beautiful!

I'll have to find the website and check. It was a metal pot, but not sure if it was aluminum.

Thanks for the heads-up and the info on toxicity to roots. The pot I'm using is anodized, but I agree that it's not worth the risk. I just wanted a good conductor for the nice cold garage slab, but I can still do that with a different material.

:lot-o-toke:ho ho ho isled i con or a rich mans toy i use honest sunshine and just cropped nice outdoor grown white widow in UK no daft bills and good smoke to boot oh what joy but with winter coming i am thinking more about led or hps
light grow indoors so i is really looking to see the results on your grow bye bye georgey
 
Re: 420 Cannasumer Reports Competition - GrowLEDHydro 300w LED vs. 400w HID

The setup for the grow is coming together in my head.

Hempy (the person), is using hydroton in the bottom up to the hole, and pure coco above the hole. He said the coco had problems draining without the hydroton. I don't understand why, but I'll take his word for it.

SS, I just found this thread because of your guidance... like some one said at the very 1st this also needs to be in active journals, at the least. A grow like this needs prominence, both for 420 and for input.

I love the detail that's going in here. Thanks to everyone for pitching in. Some of it makes my head spin :grinjoint: Ok, most of it :tokin:

SS, your attention to detail is noteworthy, thankyou. Your prowess in pot gardening isn't to shabby either :thumb:

I'm interested in LEDs, but really why I'm here is the hempy thing, the OC+, and the coco.

The last twist I read from Hempy was that he put perlite to just above the damn hole, then coco. I have a link for that if you want it. What I thought I understood, was that he felt coco stayed too soggy below the hole, because it held water so well. The perlite at the bottom helped the coco above drain a little more than just a pure coco bucket.

It kind of makes sense to me cause I made a hempy/perlite bluish to go cup for a clone, and I can see that h2o does sit at the bottom. As a matter of instance, when I first filled the cup with water, it raised the perlite 1/2" off the bottom of the cup, and I couldn't push it back down. That perlite was locked in tight. Real tight. There was water at the bottom, though. Perlite has settled back to the bottom after a week. Maybe just an interesting phenomenon?

Any way, water stays below the 2" hole as visible water, and water that I could pour out. In my 3gl perlite hempy pots with flowering girls, there is moisture an inch below the surface 2 days after I water. Even chunky perlite seems to wick, coco has got to suck it up.

When I've taken the clones in perlite hempies out to clean them up, and I tip them, water comes out the damn hole. I don't think it's commonly called a rez for nothing, and coco down there after a while could be a sloppy dang mess.

Mr. Hempy also waters every day in flower. I want easy, but I also want plants like Hempy grows:

Something's gotta give :)

Gonna try some coco variations, but I dunno if a 12 oz cup can correlate to a rose pot. And, if it takes work, I'm willin' :blunt:

I wonder what that big gnarly beauty looked like with her fan leaves.
Lollipopped naked like that, she sure is something!
I'm curious about the lights that grew colas top to bottom.
That's a 5 gallon bucket she's in, isn't it?

:welcome: georgey!


Yep, can't beat sunshine for cost and efficiency. I have a few lowryders going outdoors right now for that very reason ;).

You won't get the same yields indoors, but you can certainly grow some nice plants.

stay tuned and we may get to see a couple of tents stuffed with Pure Power Plant buds. Now wouldn't that be nice? ;)

appreciate your input on this Horse, and I'll bring it up to admin.

I love the detail that's going in here. Thanks to everyone for pitching in. Some of it makes my head spin :grinjoint: Ok, most of it :tokin:

we have some very educated and smart peeps participating, and some of the discussion is over my head also, but that's OK, we all bring different gifts, talents and knowledge to the table.

SS, your attention to detail is noteworthy, thankyou. Your prowess in pot gardening isn't to shabby either :thumb:

My OCD has it's benefits when it comes to attention to detail, lol. Hanging around here at 420Mag and absorbing much good stuff is what I credit with whatever success I've had as a grower. If I wasn't able to interact with other growers like I do here, things would be very different.

I'm interested in LEDs, but really why I'm here is the hempy thing, the OC+, and the coco.

Pretty sure that's going to be the setup for this grow, but I'm probably going to go with Dynamite purple instead of OC+.

The last twist I read from Hempy was that he put perlite to just above the damn hole, then coco. I have a link for that if you want it.

I'm thinking of going with hydroton or perlite to just above the hole.

What I thought I understood, was that he felt coco stayed too soggy below the hole, because it held water so well. The perlite at the bottom helped the coco above drain a little more than just a pure coco bucket.

coco retains a lot of water, so makes sense that it would work better with something else below it to help drainage.


It kind of makes sense to me cause I made a hempy/perlite bluish to go cup for a clone, and I can see that h2o does sit at the bottom. As a matter of instance, when I first filled the cup with water, it raised the perlite 1/2" off the bottom of the cup, and I couldn't push it back down. That perlite was locked in tight. Real tight. There was water at the bottom, though. Perlite has settled back to the bottom after a week. Maybe just an interesting phenomenon?

Perlite will float in small containers when you do tests for wicking, etc. I had that problem too. In a larger bucket, however, it settles down nicely and doesn't do that.


Any way, water stays below the 2" hole as visible water, and water that I could pour out. In my 3gl perlite hempy pots with flowering girls, there is moisture an inch below the surface 2 days after I water. Even chunky perlite seems to wick, coco has got to suck it up.

coco wicks and retains water much better than perlite, but it doesn't compromise aeration, which is the main reason I'm using it. Extended watering frequency without compromising anything to get that.


Mr. Hempy also waters every day in flower. I want easy, but I also want plants like Hempy grows:


Something's gotta give :)

yup ;)

I wonder how long he vegged that monster, lol. That does look like a 5-gallon bucket, but I believe Hempy said he has grown huge plants like that in hempy buckets half that size.

That thing has gotta be the biggest indoor plant I've ever seen. Would love to see the grow setup that produced that.

Between poison ivy and their dam helicopters
I'm denied birthright resource
That's OK on this fine day, we've great lamps to grow with
Of course

things will change, hopefully soon,

The PPP mom is doing great. There's something about 6500k.

I ran into a mag deficiency with these clones because I didn't prep the coco with some cal/mag after rinsing it. The lower growth shows it, but the new growth is very nice after I switched to RO water supplemented with cal/mag and PH'ed to 5.8-6.0.

For nutes on this grow, I've decided to go with Dynamite in the purple bottle, which is a controlled-release fertilizer that you apply once at the start of the grow.

It's not a "mainstream" nute in the world of growing cannabis, but I honestly think it can work better for me than anything else, so I'm going with it.

The OC+ rocked my last grow, and I think the DM purple may perform even better.

Yesterday, I added a tsp of Dynamite prills to each 5" pot by poking some holes into the coco and dropping the prills down in there.

So, from here on out, all they are going to get is water, supplemented with cal/mag if necessary. If they aren't developing well down the line, I may consider adding another product, but otherwise I'm going to just use the DM, because I want to see how it does alone.

Six of the clones are very uniform in size, and two are smaller. I'm going to put four in each tent and split them up so things are fair and equitable.

Going to transplant into hempy buckets, veg them a few days longer under the LED and HID, and then LST them and flip them after new shoots have developed.

Things could change a bit, but that's the current plan and I should have the comparison grow fired up very soon.

:thanks: for your patience peeps,

we're almost there ;)
 
Re: 420 Cannasumer Reports Competition - GrowLEDHydro 300w LED vs. 400w HID

that mom looks great!

Bro your gonna love the DM! its doing great for me, i love it! on my next grow i am gonna ditch the OC+ to because what i see in my grow its not even close to the DM with my setup. i will be very interested in how it vegges though; since i skipped that phase. i would also love to see how it dose in coco since thats gonna be my next growing method. but i do think ur gonna be very happy with the purple DM, i feel its truly amazing from what i see with my girls. IDK bro maybe its my temps or something but the DM is making the OC+ look bad on my gro. ill post pics this weekend of each girl and show you guys. i am just hoping the OC+ is just making them bloom latter or something, because somethings up? worked great for you so i dont understand? do u think ur girls took longer to start budding using OC+? I just dont understand? 4 DM plants are doing great and the 2 OC+ ones arnt?
