Things progressing nicely... stretch almost over...

Flat,
how's your ventilation? got muffins below the bulbs and venting up top? looks like you may be suffering some heat stress.

The muffin fans on the lowest speed is your best friend in vert, i had to learn that the hard way but having them on the lowest setting made a world of difference.

Yes,with really good results..
I've done much flood cloning and seed germinating...

You can go from seed/cutting to harvest, all in the same pot,as far as im concerned..lol...

What was your strategy? Did you take a really large cut? For some reason it hasn't worked for me, but perhaps I'm impatient or I need to add humidity or something. The veg spaces are kept at 70 RH roughly, so I figured that would be sufficient, though I could add a piece of tupperware on top to add humidity and create a little microenvironment w/ near 100% humidity.

I've just been cloning in coco + solo cups under a humidity dome so far with great results, but I would rather just use purely Napa the whole grow and not have a random 16 oz chunk of coco in there.

Yep I've got the Honeywells underneath them and the ventilation on top. No heat issues at least according to the thermometer which is placed just above the leaves... at most 80 F. I'm extracting air theoretically at 500 cfm (in actuality probably closer to 250 cfm, and my space is 250 cf). Room is also temp controlled and will blow in cold air if necessary. She looks healthy to me, but I'm nowhere as experienced as the grow gods on these sites...

 

[flat9]

I know, by the way, everyone says "lowest setting" but I've kept them on medium. The reason being that when I put my hand on the ceiling directly above the lamp I couldn't feel any air coming up at all even on medium speed, so I figured it'd be best to use the fastest speed possible that doesn't bounce off the roof of the tent.

for what it is worth flat9, i wasn't happy either with the air flow in my tent. I took an 18" square piece of ?? 1/2" plywood and cut, with a hole saw, a 6" hole in it. put it inside the tent at the tents center. and with 18" pieces of 2"x2" pine between the roof horizontal poles and the plywood. then cut a hole in the center of the tent using the hole in the plywood as a guide. fan goes outside the tent sucking from the 6" hole in the roof of the tent.

my logic being that heat rises the plywood and 2"x2" boards give a 2" 'dome' effect to the tent, where heat would rise and collect at its' highest level, exactly where the fan is. i didn't like sucking from one corner of the tent where a 6" exhaust hole is provided by the tent company. i do use 3 of those little personal fans $5-$8 each. one is mounted low on the wall between each plant. they stay on 24/7 blowing up and into the wall as well as a 4th fan on the floor in the center of the tent, on the bulb. ive been very happy with the results.

I had great sussess with taking a lager cut 6"-8" taking the lowers off and leaving the top 2 sets of leaves.

Cut the bottom at a angle and dip in cloning powder/gel.

Make a hole in the napa with a finger almost to the bottom and place the cutting...
6-10 days later...Bam,new growth 95% of the time.
No hood needed... Your micro environment at the plants height will be around 80-100%.. With 90 minute floods...

The smaller cuttings took longer to get going and I found
a hood for the 1st 4-5 days made a difference...
(for smaller cutting)Simple clear cup over the cutting...

Smaller cuttings having about a 80% success rate and taking longer to get there...

If you go back in my Vert show this season you will see
that I even took a broken branch and with no prep,
placed it in a pool and though it took 10-12 days.
It grew as well...


Ultimately,
I came away with using buried 1L air pots and DIY air pots in the larger containers and as the cutting grew,I simply moved the air pot into a new container or veg area...

You can wait till fully flooded and wiggle the plant a little and it will come out clean but the less stress,the better IMO....

Good luck Flat... Im sure you will figure it out...

 

[flat9]

Smart idea. I think I'll try punching a bunch of holes in a clear solo cup and bury that (16 oz instead of the roughly 32 you were using... hope it will work). Imagine this will help keep the little ones stable....

Yep I've got the Honeywells underneath them and the ventilation on top. No heat issues at least according to the thermometer which is placed just above the leaves... at most 80 F. I'm extracting air theoretically at 500 cfm (in actuality probably closer to 250 cfm, and my space is 250 cf). Room is also temp controlled and will blow in cold air if necessary. She looks healthy to me, but I'm nowhere as experienced as the grow gods on these sites...

hey there flat9 she looks healthy to a point, that being said you can see a lil bit of stress in the boating of the leaves, I would have to say from my own opinion that is either from a PH swing or over feeding. It looks like the plant is more sativa leaning with thinner blades and stretchier nodes from my experience with sativa's they tend to be finicky eaters and don't need no where near the PPM's that more indica dominant plants would be accustomed to.

also you say you are running 500cfm in a 250cfm area ? Is that 500 cfm's loaded or just the base stats on the fan? If your running a carbon filter I would cut your cfm rating in half on the fan and go from there if your still pulling 500 cfm's loaded then your ventilation is fine thats right at the 2x/min that you want. Hope this helps figure out whats going on besides for the boating of the leaves she looks nice man keep up the great job

thought i'd share my 30 days of growth...

there are images in between but i can only load 5 at a time

 

[flat9]

Looks great grow4flow! Mind sharing your feed and drain tube setup on here? It looks like you're using D9's, and I bet some who aren't near a hydro shop would greatly appreciate it....

... actually it looks like barb fittings on the return, but nevertheless the PVC feed would be appreciated.

 

[TerpeneTom]

Question: Those sowing cannabis within PPK's, will they experience greater efficiency regarding H20 allocation/location and hydraulic redistribution because of the inherent tap root (opposed to clones).

Does this apply for all grow methods regarding Seed vs. Clone propagation?

Am I not understanding the function of the tap root? There any validity to this?

Thanks!

 

[Garhart]

Very nice looking plants !

 

[hotboxes]

Looks great Grow4flow. Just wondering why you went with such a small diameter return line? This being said wouldn't you want to return the water faster than its being pushed in? I know that flooding the medium in this system help a lot, but if the bottom containers can't drain the water back to the control rez for complete equilibrium they could overflow depending on how long you are flooding for. Just my thoughts looks great never the less, super clean looking set up keep up the great work bro.

 

[Grow4Flow]

flat9,
You are correct, those are 3/4" barbed fittings. The feed manifold is made up of 1/2" PVC and 1/2" ball valves to control the flow at the tub. each tub is fed from the single 1/2" pvc pipe coming from the pump. i can take pics later when lights come on.

Garhart,
thanks.

hotboxes,
Thank for the words. The return (3/4") is larger than the feed manifold. The return water is only going to move as fast as the res can be drained since the res level determines the level of fluid in the lower bucket of the module.

I have ran it for a week this round before adding the clones and the fill/drain times were pretty consistent at about 82 seconds for a complete cycle. I use the ball valves to slow down the fill to the tub which now floods with nutrients 1/2" above the media in about 45 seconds. This time though, i filled the tail pipe with 2 inches of lava rock to add to the drain speed and hopefully build some beneficial. Not sure if anyone else has experienced this but after a week of running my media has changed color and there is a film on the surface of the media, benies maybe?

 

[flat9]

Does anyone recall what D9 used? I think he had some sort of electrical conduit and what not, but I'm not sure...

hey mate that looks really nice and clean what veg time is that from the exploding growth of clone to bush?

how long are you top feeding for on each pulse? does it saturate the whole media when u feed from the top with that periscope stylee top feed, does it just all trickle down one side leaving air roots at the other side, keep up the good work mate

 

[Grow4Flow]

Sqydro,

Veg time was 32 days from rooted clone, feed time is about 45 seconds which pours into one side of the pot and fills until the nutrient is 1/2" above the media.

The feed force creates a hole in the media where you can see the roots but at this point it doesn't matter as there is so much shade.

Another thing i forgot to mention is that i do not use Vert lighting, i use Adjust-a-wings with DE socket kits and Gavita Double ended bulbs which is the best lighting i have ever used so far, i am actually getting better penetration through the canopy firing at 600W than i did with vertical bare bulbs. I don't think i will ever go back, i will be firing at 1kw soon.

Yeah that is beneficial bacteria created from washing water over the lava rocks, it's a really good thing D9 and I talked about this before since he used to run bio buckets and that system depends on BB to sustain growth. The only issue we thought might happen is if you would get enough draw on the rocks to wick enough liquid up into the medium.

 

[TerpeneTom]

Why is this a phenomena experienced specifically with lava rock? Is it due to the improved flow? Not because of the surface area, correct?

nice one so the full media is soaked saturated each pulse this must make them explode then any feeding needed inbetween can be taken from the wick its self

bennies inhabit lava rock cos its so pourus and gives them great space to breed, there essential in RDWC if u wanna make a filter or even put some in res and boom got ur benny colony in there i used to make benny tea for my RDWC was amazing root balls were insane no airstone heath stylee

anyway back to PPK........
