Blue Widow & Sweet Deep Grapefruit 400W Coco Grow (Tropf Blumat)

I'm sorry I don't know what foliar feed solution is, do you mean for the vegative phase or something?

Thanks for linking me to your forum link from the gallery, will sub for this one. I am myself on my 2nd grow, and 1st in coco.
I myself just set up my grow if you're interesting this is what I use;

Strains: 2x Black Sugar , 3x White Widow x Big Bud , 2x BubbleGummer , 2x Emerald Green (Norden seeds, have not grown this myself yet), 1x Lowryder X from "norden seeds" It's a strain a guy here in Sweden started making I'm not sure how, I have grown it once before in 6.5L soil plastic pot and got 1 ounce from it.
Lightening: 400w MH/HPS /w cooltube (1 GIB Ballast PRO-V, GIB XTreme HPS bulb, GIB MH bulb, but I am not certain yet if I will use 12/12 from seed or veg 1-2 weeks)
Tent: DS90 II tent (3x3 feet)
Ventilation: 300 m³/h ventilation fan with carbon filter, I have a RPM-regulator to make it less noisy
Watering system: Trumph-Blumat dripping system /w 50L tank at the moment. (It's a passive system using a tank elevated higher than the nodes, I recommend it. It's kind of like AutoPot but with drippers instead.)
Pots: 10x Airpot 6L but I upped the bottom so there is about 4.5-5L of medium inside
Medium: Canna Coco Plus+
Nutrients: Gold Label Coco A+B, Roots, Ultra MG, Ultra PK

Currently 7/10 seeds have shown. I accedentily killed one seedling, hopefully it was not one of the Black Sugars .. I forgot to mark them up properly so all I know is wich ones are LR X and Emerald Green.
I can get more information about the strains from norden seeds if anyone wants it.

wow that's a nice set of plants you have there, thanks for sharing all of your info.
so could you explain a little more about your blumat reservoir setup? i have my reservoir about 4 feet in the air at the moment and it works really well, i guess the part where you said "(It's a passive system using a tank elevated higher than the nodes, i recommend it. It's kind of like AutoPot but with drippers instead.)" kind of confused me a little.
Oh and one more thing about the blumats... since this is my first time using them i'm just going by what people say on the forums and so far it has all worked really well... my only question is whether there should or should not be any runoff? at the moment i have mine dialed in to not have any runoff but everything still stays moist and the plants are responding well to it so i figured i was doing it right.

Here is a pic of my reservoir that i mentioned above....
let me know if you have yours set up in some other way that might be better... as of now i haven't had any issues with this method but am always open to new ideas... especially from somebody using some of the same products as me.
thanks again!

Thanks I created a thread, link is last. Currently mine is also 1.2 meter (4 feet) up from the floor, but it could be lower. I had a furniture where i put it on, ill take a picture you can see it below. Well what I meant was that it's necessary to have it higher up than the blumats, my pots are maybe 10 inches high, so the resevoir should be atleast 15 inches from the grounds I think. The higher the better I've read, but as long as none of your hose goes above the lowest place in the reservoir, it's all good. And so your setup is very nice, no problems with the reservoir.
Regarding the "It's kind of like AutoPot" I mean't that the water is regulated at each pot (every blumat) or in autopots case the aquavalve in the tray, and that it's passive by using gravity.
I hope you understand what I mean, I'm perhaps not the best at explaining things.
About run-off, I am honestly not sure myself since it's also my first time using them. But I will ask a guy on my national forum about this. I don't get the feeling that there should be any run-off but now that you mention it, perhaps there should be? Maybe someone with more experience can tell us. Right now my girls are small and I just transplanted them, so they don't need the whole pot being watered, but I think later when they've grown a little bit you might need to regulate so there's some kind of run-off to be certain there's water in the whole pot.
Anyway, I will look into this aswell. I'll post if i find any good answers!



EDIT: Here's a link to my journal: https://www.rollitup.org/grow-journals/497030-10-plants-400w-mh-hps.html#post6806227 With my new profile.

cool, i think we are on the same page...... as far as runoff goes, i noticed that my sweet deep grapefruit pot was dripping a little with runoff but after an hour or so it had stopped so i didn't mess with it. hopefully somebody will chime in with some info on the runoff question.

Yeah Right now I'm just hoping my girls don't die from underwatering .. going away til sunday!

im sure they will be just fine.... i left mine alone for 3 days and came back to wider plants and perfect working drippers.
i think something like a huge clog would be the only thing that would sabotage you but i wouldn't count on that happening.

so this is just going to be a quick single picture update but there will be more to come tonight/tomorrow.

I have a question that hopefully somebody can answer....
the plant on the left (sweet deep grapefruit) is showing signs of slight curling or "tacoing" on a few of the fan leaves.... they aren't very noticeable but you can still pick out a few spots in the pic.... the blue widow on the right doesn't have this problem so it kind of has me confused... i don't believe it's heat stress since the other plant would probably do the same thing... maybe i'm just worrying too much. I actually noticed some slight curling about 5 days ago and it hasn't progressed or anything.

any ideas?

so can somebody help me with a question i have?
is it ok for these plants to be as close together as they are?
im sort of wondering if i should move them apart a little bit or not.... i've noticed some people doing grows where they have plants spaced as far as i do and their grows seem to do fine...

I am pretty sure it doesn't really matter, however if you space them enough to never cover each-others fan-leaves I guess that's possibly a bit better? I doubt you'll see any difference though. The bulb you have should be able to penetrate a few leafs down anyway.

yeah that's what i was thinking... i'm really not worried about it one bit lol.

oh and here is an updated pic at 28 days from seed... SDG has taken really well to the topping... the blue widow isn't too far behind.

Looks great I just came back from my days away, one girl looked like she had been underwatered, and it turns out the drip-hose was too pressed by having it on maximum -, but when i just pressed it on the sides it went from _ to O and water came out. Hopefully it won't die.

should be fine, they tend to make speedy recoveries from underwatering. i have a new pic update that ill be posting in a few hours

here they are... pic was taken exactly 32 days from seed

Cool. Are you still in the vegatative stage? I am running 12/12 with the MH-bulb right now, will switch to HPS (10% blue or something) in a few days I think. The MH-bulb is specced at 54000 lumens, and the HPS at 115 000 lumens... I guess the HPS should be better even tho it's not a lot of blue light.

Edit: I changed the bulb now, I hope it won't disturb them that I opened the tent a bit for a minute or two.

By the way, is that insulated ducting you have working it's wonders? I am very annoyed by fan-noises when I try to sleep, so I might buy a few metres of it.

yeah im still doing veg at the moment, i wont induce flowering for another 3 weeks when i switch to my hps. right now they are 1 ft tall since i topped them above the 4th leaf set a while bak and it helped them to branch out rather than just stretching up.
the insulated ducting works pretty good, i am using it more for keeping the temps more stable since the ducting runs like 10 foot until it gets to the flange at the ceiling... my exhaust fan is in the attic so i cant hear it anyway but the heat from the light was radiating through the regular ducting and heating the room up a few derees more than what i wanted. i have noticed a difference in the noise also, it took away a lot of that "whoosh" sound caused by the suction

here is an updated front view pic

Cool, I am planning to possibly move from my tent to a stealth-cab instead, but still maintaining 400w etc.

Your girls will become huge girls, looking forward to that I am off to calculating on my cabinet and thinking of ideas to keep it all silent...


About the 400w HPS i changed to, the specs are

GIB FS XTreme 400 W ger:
58 000 lumens
128 000 phyto lumens

I think it's a decent bulb, havent let me down yet anyways..

you should have no problems with that bulb. I even had good results with a cheapo 15 dollar bulb that came with a reflector that i bought a long time ago. right now i have a 400w hortilux super HPS enhanced spectrum bulb waiting for 12/12 that i'm pretty excited about using, i've heard good things about them and i think that these 2 plants are worth it. it's funny how all of these places online charge right under 100 bucks for the damn thing but amazon had it for under 60 lol.
i'm about to head over to your journal to check out the new pic you uploaded.
peace out!
