The plants look great with the exception of the plant that is still in the different nutrients. The nutrients are called sugar peak and we have found their application is best suited for soil based plants and not hydroponics. The nutrients are looking kind of murky in all buckets. There are some fine granules that washed out of the hydroton so it is about time for a nutrient change. All the nutrients will be GH 3 part and I will do a full nutrient change tomorrow. Here are some more pictures. Thanks for the comment Earthy Danky, do you have a link to your grow so I can see what it looks like? I will follow your grow too even though we are in different stages.

I don't have a grow log just yet. I am waiting to get a camera. Right now I have 7 clones growing organically in soil and two growing in a 10 gallon DWC system. I use the 2-part GH FloraNova nutrients with liquid karma, Pure blend metabolic compost, hygrozyme and superthrive. I have a 600w Hortilux HPS. And I grow a unknown canadian sativa that a friend brought back from some kind in vancouver.

thats pretty cool, sounds like you have a good operation going there too. I'd be interested to see your DWC pics when you get them. Also, how do you like the floranova? we were going to go with those nutes but they ended up being a little too expensive for our budget. Then again you only really have to invest once a grow since the nutes are more than enough to last for bubbler systems such as ours.

FloraNova is great... has molasses in it, makes the buds real sweet. I was thinking about trying the bonticare pure blend but I'm not sure their are so many good options. And if this DWC grow does exceptionally well then I am gonna make 3 more and have a 40gal w/ 8 plants. And i'll harvest 4 plants every 4 weeks.

Did a nutrient change today on all three plants. We upped the nutrient formula to the 3-2-1 regiment as per the label on the GH bottles. I also went to GH's web site also and found a handy conversion guide and it says we are right in the target range in terms of PPM. We are going off the "growth" guidelines.

how big did u say that space is ? ive got 2 in a space 1.8m by .9 by 2.2 h , hopen 4 a pound there a bout 6 foot with a week 2 go many thanx

Isn't it day #13? and I would becareful with the ppm. You jumped 1000 ppm in one change.

deftdrummer · #33 (**permalink**) Jun-03-2007, 22:26

..gas..: "The table measures 3.25 ft in width and 4.33 ft in length making the total square footage: 14.07 sq ft."

Earthy, yes I guess technically it was day 13. I did the nute change late last night and was stoned out of my mind so I didn't remember what day it was! Anyways, thanks for the advice about the nutrients. I was a bit worried myself but I did some reading on here and found that most people think beyond 1200ppm for vegging is overkill and is a waste of nutrients. Ours was a bit high at 1350 but I should also make it clear to everyone that our tap water is 130ppm by itself. So factored in, thats 1220PPM of nutrients which I'm not too worried about. After all, its slightly less than the recommended dose for the age of the plants per the label. So far they seem to be responding really well! Stay tuned.

The plants seem to be doing fine. I took some pictures to show the first signs of the roots dropping down into the nutrient solution and also coming out the sides. They are thick and white, just the way they ought to be! You can see the taproot in one of the pictures going down as far as it can. Since the roots have started to drop into the nutrients we will transition to full 24hr drip so that the bubbler can be on to oxygenate the roots and nutrients. We are hesitant to do this too early however, for fear of over-watering again a little too early before the roots are ready to fully absorb the nutrients 24 hours a day. We will probably do one plant at a time to see if it has any adverse affect or not.

Some more pictures from this morning. The biggest plant has the most roots down in the nutrient solution now so the bubbler is on 24 hours. We will switch the other two once the roots develop a little more. The weather has cooled down here a little bit so the grow chamber is a little cooler. We are going to hit flowering at the hottest point in summer so we are going to have to get that extraction fan next before anything else.

I will be watching your grow!The set up is sweet great job.good luck,Peace

hey, neat thread. How does the pump get water to the dripper? I don't really get it.

Earthy Dank · #38 (**permalink**) Jun-06-2007, 03:08

lol yeah how does that work? Drip and bubbler?

deftdrummer · #39 (**permalink**) Jun-06-2007, 03:20

Hey guys, I drew up a little diagram that might help you get an idea of how the system works. Its a rough sketch in fact if I weren't stoned I probably wouldn't have put even that much detail into it, but hopefully it helps. Very simple design actually. And yes, bubbler and drip system.

They are starting to grow faster. Looking good. How big are you gonna let them get before you flower them?

Thanks earthy, they definitely are getting bigger and doing better as the days go on. We are especially pleased with the runt in the back as it was taking the slowest to the nutrients. It is still the only one that doesn't have roots down in the nutrients yet but it will any day now. As you can see the roots are looking great and dropping down into the nutrients. We now have it on a cycle where the drippers turn off at night to let the roots grow a little and to allow some air circulation in the roots and clay pebbles. We have been slowly diminishing the nutrients down to the 1100 & 1200 range by just adding water daily and diluting. To answer your question we will probably flower at about 1 ft tall. Within the next week we will top the plants and I will show that in detail. The tallest is about 7 inches tall so we have a little bit to go yet before topping. Topping is recommended after the 2nd or 3rd node but we will wait until the third gets fully developed before topping since they are just barely at 3 nodes right now.

these are pics from yesterday

Hey deft,
Where did you get topping info at ? Never heard of anyone topping that early . I have read conflicting info on this at a few dif. sites . 6-7th node / some ppl. wait till nodes are alternating etc... I can't wait till nodes alternate tho I don't have enough headroom .
Peace
