raise your Ph to about 5.8 now and they will have more nutrients available to them at this cycle of life.

There is a chart in the FAQ section that will show you the different nutrients available to the plant at variable Ph levels.

Charts & other stuff you can use

Hey Deft ,
Hope I'm not a pest .
Also in response to Freewheelin's q's about both systems being intergrated = If airstone ever clogs you have dripring , dripring clogs you have airstone . Plan B type thing , is why I did it w/ mine . If neither ever fail = 1 way oxygenated root sys , -n- happy happy girls .

I'm at 5 weeks now w/ my virgin run of dwc / drip combos w/ only 2 buckets and I'm blown away w/ results . I bet 3/4 to a full LB. per bucket if it keeps getting denser - never done the strain before ?
Peace
Crispi

Thanks Zandor, your wisdom is always much appreciated. I will make the adjustments. Do you have any good resources that specifically tell what elements MJ needs during all phases of growth? This would help myself and probably others in maintaining the correct pH at all times.

Crispi, no need to feel like a pest I enjoy anybody that takes interest and is willing to contribute to the thread, after all if it were just me talking nobody would benefit cause I'm no expert. By the way what you were saying about the dual system backup is an excellent example, I never thought about that but it makes perfect sense. Thanks crispi

WoW this is a freaking Awesome thread. i am going to be trying out the bucket pretty soon. (Noob) and this is a great reference to look over for my 1st grow. thanks!!

Now for the questions hee hee...

On the halo's then was something mentioned about salt build up. could you use distilled water to prevent this? or if the tap water is too harsh?

you have the water cycle set 15 every 2hrs. when are you going to switch (or recommend) it to 24hr?

deftdrummer · #55 (**permalink**) Jun-12-2007, 21:26

5150 thanks for tuning in and thanks for the compliments. Regardless of what type of water you use you will still have salt buildups. This is due to the nutrient solution staying when the water evaporates. Also, I am no longer on a 15 min every 2 hours watering cycle. We are currently on 24 hour drip systems since the roots have dropped down into the nutrient reservoir.

Hey Deft ,
Heres a link to the current pics. I spoke of . These homemade gizmos rock bro. , 4 of these buckets will fill my 11 x 12 ft room I bet . Can't wait to see how they work out for you !

We topped the biggest plant yesterday so here is a picture of the topping site. Now the plants are all the same size and we will top the others in a day or so also. We topped just above the 5th node and there are several potential bud sites below it.

Hey, Deft...just wanted to say that I really like the thread. Great log. Great build. Great consistency with your info and lots of awesome pictures. Thanks for showing me up.

Good stuff, man. Will be watching the whole way for sure. Your plants look excellent as well.

Hey green fog thanks! This is my first grow log and my first grow that i'm trying to be detailed on, I figure if anything goes wrong along the way at least people will be there to help rather than just posting a random thread somewhere in hopes that someone will help me out. I checked out your grow and it is very similar to mine except for the soil(?) We have 3 mothers under a T5 also, I think your grow log was pretty comprehensive, I actually looked at it a few times before making this one and it gave me ideas. Thanks for checking it out I can't wait to get some knock you on your ass chronic from this grow.

TheGreenFog · #60 (**permalink**) Jun-13-2007, 16:36

Well, I'm not sure if you're sure you looked at the right one. In the JOURNAL, there is no soil used. It is rockwool with hydroton rocks in a dripper/ebb & flow system. In fact, I am trying to get a second log up...been trying for a while. I'm just such a perfectionist, that I wanted to make a short pictorial video of the first grow to start off the second one, but that is taking WAY too long, so I'll probably just throw it up there and smack the video onto the end of JOAMM I when I get around to finishing it. LoL

Be cool.

Off topic but the bike in the pic is that an R1?

Looking into trading my dirt bike in for an R6

Back on topic Still a great thread going to save this thread so when i start have something to compare to.

deftdrummer · #62 (**permalink**) Jun-14-2007, 03:25

5150 it is a 2007 R6

06-14-07 Day #24 of Veg.
Cab Temp: 82F
RH: 49%
Nutrient Temp: 75F
PPM: 800-1050
pH: 5.7

We lowered the pH to 5.7 so that it will rise to about 5.8 towards the evening and then be lowered again. The root systems are healthy on all plants although the stunted plant doesn't have that many roots coming out the bottom yet. We will top the other two plants hopefully in the next few days.

6-16-07 Day #26 of Veg.
Cab Temp: 83F
RH: 55%
Nutrient Temp: 79.5F
PPM: 934-1025
pH: 5.7

Although I don't seem to notice, the pictures tell me the plants are getting bigger every day. We topped the other two plants and should be on schedule to flower within the next week or few days depending on growth. The heat here outside has been in the 100F range daily for the past 4 or 5 days. Hopefully it will cool down a bit and give the plants a break. I topped off this morning with just water that was cool from the tap. This should help a little bit with the heat. We are planning to get the other exhaust fan very soon so that flowering will have a nice transition and hopefully it won't be so hot. We are shooting for a 4" centrifugal that will serve as nothing but an exhaust fan. Sorry about the pictures, not sure why they are so dark but you can see the topped sites clearly.

xcrispi · #65 (**permalink**) Jun-16-2007, 16:58

Sweet ,
Watching the undergrowth explode from topping is almost as much fun as watching them flower = 6-7 headed monsters . Weedhound just got like 8.5 oz. from a single plant this style .

It is almost time for another nutrient change. With the next change we will do a 2-2-2 mix of the GH 3 part which is recommended for the transition from vegetative to bloom phase. We will also start flowering at this time.

5150 · #67 (**permalink**) Jun-18-2007, 16:08

they are looking good

06-18-07 Day #28 of Veg.
Cab Temp: 82F
RH: 49%
Nutrient Temp: 78F
PPM: 1100
pH: 5.5

Today we made some changes. First the foremost, we switched to "transitional flowering" by doing a nutrient change with 2-2-2 nutrient solution. We also swapped out our 400W metal halide bulb for our 400W HPS bulb that simulates the fall light spectrum. It is quite a bit more orange in color that it emits. If you have a 400W light you can do this as long as the other bulb is also 400W. This is the closest thing you can get to a switchable ballast without spending the big bucks. At the same time we also did some routine maintenance; cleaned off the protective glass on the light and also wiped out some of the dust and bugs that collected inside the hood and calibrated our pH pen, and as it turned out it was .2 off. It was also time to raise the light a bit so we did, and it is about 6 inches higher than the plant tops.

Our little fan was no longer adequate so we cleaned off our other oscillating fan and put that in the grow tent. Now we have some good circulation! Due to the new light spectrum it is a bit difficult to get good pictures but I tried my best.

In addition to all this we also took some clones since we didn't want to be left without any clones of the grandaddy purple cause after all, we paid good money for it at the cannabis clinic. Since we are switching to flowering this was one of our last days to take clones and the donors are good and healthy so why not? We took two clones from each strain including the mothers in our mother chamber making 6 total. It's a shame, but we will probably be killing off our mothers that are in soil in order to make room for the clones we just took. And naturally, we will wait until the clones have rooted before killing them off. The strains are: goo, grandaddy purple, and rhino. It will be truly heartbreaking to kill our current mother plants but we believe it is for the better, and after all thats what they are there for. We got some smaller pots so that the plants only get big enough to take 1 or 2 clones from max. This will also enable us to have all 6 in the mother chamber at the same time without space issues.

For those that are new to cloning the process is simple and I have taken some pictures to illustrate. We went with rockwool due to its ability to retain water for days at a time before being soaked again and also because when properly cleaned from the start, rockwool offers nice soft medium for newly established roots to probe through.

First, we took all 6 rockwool cubes and put them in a pot of tap water over the stove. Some people believe only distilled or reverse osmosis water is the way to go with with clones, which is probably a good idea but we have never had any problems with tap water. You want to bring the water to a good boil for at least 10 minutes to make sure you get out all the particles out. We like to boil for this length also because it makes the rockwool nice and pliable so that the roots have an easier time and at the same time it kills any bacteria that might be pre existing in the rockwool. Be sure to let the cubes dry naturally for at least a good idea before cutting any clones.

Next, we chose sites on all donor plants that had nice small growth with few leaves since they have an easier time getting root generation under way. This is because clones with less leaves and shorter stems don't have to pull water and nutrients as far up the cutting or to as many areas. We used a clean razor blade of course, and scarified the very bottom of the stem. In other words; lightly scraped the razor along the stem all the way around. Once scarified you dip the stem in a rooting hormone; which usually comes in a powder or gel form. We use earth juice gel rooting hormone which is actually rather expensive at $10 for 1.5 fl oz, but it will last you forever.

Once dipped, simply place in the rockwool cube and place in a humid warm environment under low intensity fluorescent light and you're golden!

i learn something new everyday.

i think that is a good idea to boil the water and add the cubes to kill all the bacteria. never know what could be in there.

also from what i have read before about clones was to pick a nice healthy long stem to cut.

this info is valuable for the newb who wants to clone thanks!!!!

deftdrummer · #75 (**permalink**) Jun-19-2007, 17:17

yeah, you are right 5150 long stems are good but only to a certain point. I have found that long stems are great for making sure you can get them far enough down in the cube but that's about it. Just a matter of preference I guess.
