AK-47 in E&F - rockwool/clay medium (First Grow Log)

[subzero]

Icb.

I use a 1 m2 nft table (gt 100) in a 1.2m2 tent, 3inch rockwool cubes on a spreader mat. 6 - 8 plants veg until good root system (10 days) then 12/12. 2x 400w son t agro lamps air cooled. 775 grams dry last harvest. Jack the ripper.
Thats it.

hey sub,
i was thinking kettle...hhhmmm...res, part of the well pump, i had no idea and when i saw you only had 14 posts i thought maybe you were a noob making up names for things until i read through your post and realized you knew your shit. once i saw (for making tea) i reread your first post and had a good chuckle...but yeah, not quite as funny right now. ill go hit the bubba in a few and see whats up with that. i dont know many people that drink tea and the ones that do call it a tea pot. most people i know, in cali anyway, drink coffee.

i used those grow bags for a while when i hand watered and never had much root system grow through the holes. i have a few friends that use the coco mats under 6x6 cubes and they love it. but they say that they dont use that method in small rooms where they cant get to the other side of the trays because they cant move plants around to inspect.

sounds like a cool setup. so 800w total in a little more than a 3x3ft area 6-8 ladies with a 10 day veg. hhhmmm.
now some veg faster than others but i normally do 9 per m2 (3 rows of 3) under 1000w with a 10-20 day veg and get about 600-750g
(the sour d i get is almost no veg, 11 week flower, 800-900g) sounds like we get about the same but you use 200w less than i do and likely have an easier time controlling heat. i have a lot of big coco filled root balls to get rid of and you have 8 3x3in cubes and a mat to dump? im thinking i want to try this method out at some point.
so your 400s are right next to each other? what neuts?
sorry about all the brain picking but im very intrigued with the way things are done across the pond. my wife is german and if we ever move over there i'd like to be informed on the way things are done there. i guess the US looks at lighting and growing the same way we look at cars, bigger and less efficient is better.

We drink coffee too but we boil the water in a kettle before we add it to instant coffee, same with tea! Your right, you cant move them at all but can easily see the roots under the cover. 1.2x1.2 is allll most 1.5m2 but with nft you get absoutly explosive growth if you haven't tried it.. do. If you want some ideas give me a shout. You do need them in a tight space when they are mature because they will fall over otherwise. lack of support is the only problem. canna aqua nutes until I went ro (they put chloride in our water here that does not evaporate off also pesticides from the local farm land and lots of estrogen tooo yuk..) Now vitalink max 2 part soft water (very clean nutes MJ specific for ro), and pk 13/14 for 1 week 3/4 strenght as soon as you see the buds spiral, if they have formed a cola its too late. I had a giggle at your "hot hallway" statement! Scaley kettle AND a hot hallway! fucking stroll on! whats he gonna do???? :stoned: We had kettles in canada too. oh yea agro bulbs produce about 430watts each new so we are pdc, yes i put them about 8 inches apart side by side in reflectors not cooltubes. They dont like you growing in germany! have a look at some uk hydro sites, things have really come along way in the last couple of years. oh and the mats i am refering to is like a thin layer of fiberglass before you put the resin on, (i'm guessing you still have surfboards in cali dont ya?!)

Sorry bert, we'z a bit off track here now.

Peace.

Hey guys I don't have much time to talk because I'm in the middle of a raid that I was late for because my internet was down due to a storm but I wanted to say I had some comments but I'll have to to em later.

With my other plants that I've tried, the roots grew out the bottom, but not very many, and non in the light. All this gear I have was all recommended to me at a time where I had honestly not done any investigation due to paranoia so I went into this whole thing kind of blind and now I'm trying to pick up the peices.

[bertoxxulous]

To expound on the discussion of my grow system. I kinda like it from what other grow systems that I have seen. Now, it still remains untested for me if the root issue is really going to be a problem because I've fucked up my other 3 grow attempts so the plants were in much less than favorable conditions and root growth could have easily been stunted. However, there is a good solid 2 inches of hydroton in a bag that is close to, or at least 8 inchs in diameter. So, from my standpoint I would assume that there is enough room for root growth. I am a nub to growing however, so all my assumptions could be based on a false sense of logic, so don't think I'm arguing, I'm just trying to shed some light on to my way of thinking about things here.

So now you guys have seen a few pics of my F&D setup, what would YOU recommend as the best solution for growing here? Please be very specific for my benefit (I.E. 4'' rockwool cubes, etc.etc.). To state again, based off some recommendation from other folks on this site, I place 1'' rockwool cubes on top of about 2 - 2.5'' of hydroton in 1gal. bag (approx. 7'' diameter) and the filled hydroton around the 1'' cubes so that only the tops of the cubes are showing. The bottom of these bags have 4 wholes on 4 sides of the bags. I have the bags positioned just so that the top of the water level barely touches the bottom of the rockwool cubes. From my understanding, and from what I'm using, this is the best possible solution with what I'm using, but from the way you guys are talking I'm using least optimal stuff, or is it more a preference thing?

:clap: On a side note to this post, it seems my PH and nutes have stabilized after this weekend and the plants seem to look bigger and more healthy every day. I can only try and hope.

No, don't get us wrong your set up looks great, it WILL work fine, there is no best set up, everyone has their own techniques and tricks that they tweak over the years. We were just really comparing how things are different in the uk to north america and sharing a few ideas. I just assumed the roots would grow out of the bags and into the tray. If this is the case you should cover the roots. Alot of people dont get on with rockwool, personally I love it. If everything is looking healthy just keep it up, you will succeed.

All the best

hey bert,
very happy to hear things are going well!:thumbsup:
its most definitely a matter of preference. there are so many types and brands of mediums, watering methods, lighting, and you can use them together in different ways.
just general advise that i give to every person i help get going is even though you are told 5 different ways of room setup and growing methods its best to find the guy with a method thats easy to follow, has step by step instructions on what to do and where the plant should be, consistent good yields...., and most of all will be there to answer any questions, and then follow his method to a tee.
ive had a few people take most or some of my setup and then use things from another friends setup and and then the other friend wont get back to them about questions and i can only really school them what i know and use, the next thing you know things get real bad.
having said that i think your setup looks great. i dont like hydroton myself but i had some good yields using it. back then i vegged in the small rockwool cubes (croutons) and tp to hydroton in 3gl mesh bottom pots. not sure if those are the cubes youre using but its hard to clean it out of the hydroton and starts to get nasty. i think i listed a few things i thought were great ideas from sub. i think youll do great this run and maybe work with this setup over the summer then go bigger in the fall when its not so hot. gotta go for now sorry.

Well. I thought things were going ok and now it looks like I'm having a deficiency, Iron or Magnesium possibly? You guys take a look. Yesterday I did a full drain and refill of the reservoir and also cleaned it out, which was filthy. Lots of sediments at the bottom this time...more than in the past. This time I'm going with 30gallons all tap, no brita water, and let the water sit out overnight to evaporate the chlorine. One interesting thing I'd like to point out though is that after letting my tap sit out overnight it dropped in almost 30-50ppm down to about 260ppm. So what I did was add about 120ml of Ionic Grow and 80ml of CalMag (for the deficiency) in 30gallons of tap that set out overnight with an overall ppm of [email protected] and 5.9ph. Also, I'm having a hard time right now keeping the temps down in the tent...today as an exampled peaked at 80% in the tent. I also believe this particular bean doesn't like heat more than the last grow attempts I had and has really reacted negatively as soon as it starts getting hot. I'm going to be putting in airconditioning this week so I hope that'll help cool the room down.

Here are the photo's from the end of the second week in the system. Notice the white/yellow at the tips, its alot worse on the new growth:

are you using air stones yet? if not you should be. a cheap must have.:thumbsup:
sub should know about the ionic but i think i remember him dissin the calmag . i myself use calmag...and lots of it. through late veg and stretch phase i keep it around 3-5ml/gal or about 1ml/l for preventative but you can use it up to 10ml/gal for retroactive. sub...??? i dont know maybe its just GH but before calmag i had a lot of dead plants...just saying...i dont know this ionic stuff so i cant say. also, with GH flora late veg im at about 800ppm.
i think they look great, but i see the pale color too. what are your ppms supposed to be in aggressive grow with ionic?
is that PM on the hydroton in that one pic with the toothpick? :wtf:

was the temp 80f or the humi 80%?

all in all i have to say if i saw whats in those pics i would have upped the ppms too.:thumbsup:
but get some bubbles going in that res like yesterday. :thumbsup:
in fact i just stopped by my buddys place and he was cleaning his res, 5 weeks into flower, for the first time and i was amazed at what one air stone could do...ill try to load the pic of it...
keep up the good work:rastasmoke:

[icbh707]

also, is there a fan on them?
im not sure about your light (got any pics of it?) but i try to keep the small ones in the middle and the large ones on the outside. are you going to top? or lst or anything? how much more room do you have to raise the light in those tents?
