    Racerx's G13 3000watt recirculating DWC grow

    Well things are back in swing finally after a month long hiatus. Its been a fresh break, but all good things must come to an end. We have drastically altered the design and orientation of our larger hydro room and are very excited about the changes. They should make for an even more controlled environment and there is considerably more space to move around.

    If you didn't see the previous setup, you can check the link here http://boards.cannabis.com/hydroponi...-grow-log.html. We have gone from 16 buckets down to 12 and have shrunk the size of the canopy. All the lights have been moved in approx 9" to better light the smaller and more dense canopy. There is no longer a central space, this is one rectangle that is about 7 feet by 6 feet. We are utilizing a screen with a frame, however the type of screen is undecided. We are going between 2"x4" and 4"x4". Ideally I would like a 3"x3" but I am having trouble locating such a thing. I like the smaller area, but it does require more work. We still have our reservoirs in the closet and we are still running the 500gph pump as well as the 35 watt single airpump for all our air needs. The airpump sits near the A/C unit in order to draw as cold of air as possible and there is a cardboard deflector that helps direct cold air at it. However...one thing I do notice is that the intake for the pump can have a 5/8" hose put on the end and can draw air from farther away. Obviously will decrease efficiency but I never noticed that.

    The next big change is the new window box which is only 4" off the wall and made with much sounder materials and a 2"x4" wood frame. This allowed us to mount our window A/C higher then one normally would so that it wont be blowing directly at the canopy but instead up at the lights and above the canopy. We have gone from a 7,000 BTU A/C to a 10,000 BTU unit that has a working recirculating feature, allowing us to exchange no air with the outside (outside air is used to move the heat thats made from the compression). Quite nifty. We have also built a box for our 50 pint dehumidifier. This box allows us to either vent the hot air produced out of the room or allows us to direct the hot air to the top of the room so that it even disperses instead of concentrating on one area. It will also cut down on the noise.

    A 6" CanFan still cools our 4 750watt digital HPS Lumatek lights, and while this is a bit overkill for the area, our 600s are in use elsewhere and hey, the more the merrier. We cut the energy from over 6000 watts to 4200 watts. Going much smaller this time as its just personal stuff (about to go into knee surgery soon so I need as much as I can get; painkillers make me vomit). A 5 foot tall carbon filter with a 10" CanFan Maxx keeps things smelling neutral, but I have yet to need to use it cause of the sealed room. Umm, what else... I guess not much in the equipment area. The room is controlled via an IGS-220 environment controller which handles temp, humidity, and CO2.

    The clones are a G13 cross, which I was very excited to get ahold of, although I hate not knowing what it was crossed with (as pure G13 does not exist anymore since it was a clone only plant). My last G13 cross was devastating and the fastest growing plant I have ever seen. Less then 2 weeks of veg and it ended up 3.5 feet tall and yielding ounces and ounces, and it even traveled 50 miles in the back of a SUV halfway through flowering! They came slightly lanky, but very established. We will probably aggressively top them once they are fully adjusted to the buckets which are at about 550ppm-600ppm with Hygrozyme and a very light 1:1:1 ratio of GMB. Our other hydro room has 4 NYC Diesel clones that came to me huge! They were done in small flood and drain tables with hundreds in the Rockwool squares still connected to eachother. They were much bigger then I would like, but so it goes.

    here we have the first 2 pictures illustrating the 10,000 BTU A/C and the dehumidifier box and the experimental 8" netpot. We decided that we wanted to experiment with the difference between a 5.5" netpot and an 8" netpot, to see if the increased room for root mass and root ball has any benefit. I dont believe it will with our setup because of the already aeroponic environment.

    The other 3 pictures are another closet featuring to 600 watt digital HPS and 4 NYC Diesel clones.

    To finish it up, a pic of the clones, a pic of the massive bubbles (the #1 thing to make your plants magnificent), and last grows finished product.

    Happy gardening. comments, critique, advice, always welcome

    Question: what kind of airstone do you use? or is it that porous tubing?

    man this grow looks awesome. I wish I had the space/money/time to make something like this. I can't wait to see where it goes.

    Have you considered hanging your lights vertically between the plants KBS style to get more bud from the side branches?

    I use a typical 6" airstone. I use them because they keep the sound down. However they dont provide any grow advantage as an open ended line. I have considered hanging lights vertically and its in the cards for the future but I would prefer a larger place to work in. This grow is a screen of green so the growth will be very regulated, just big nugs. Our A/C works well but we cant be running it all the time and vertical lighting would require more work by the A/C because the ambient temps would be atleast 8 degrees higher then they are with aircooling.

    We do a pretty massive under growth trimming when going into flowering and 2 weeks into flowering. This keeps nice airflow and focuses growth to the top nugs. This is all personal stuff, I dont sell, and everyone knows the best stuff is the big main colas. I am shooting for around 1/2 gram per watt of really really good stuff, but if this G13 is anything like the last strain I grew, i should be able to beat that.. Our last grow in this room went well, but some specific mistakes were made and affected the outcome to some degree. Those have all been addressed and there should be very little hiccups this time around. The extra space will save much frustration and hopefully less likelihood of contamination.

    PS. If I didnt mention it before, I use a 35 watt pump for the buckets and a 12 watt for the 2 reservoirs. This keeps things really bubblin. In my small 4 bucket closet, we use a single 35 watt pump to power the res and all 4 buckets and they really rage it.

    nice. as for vertical lights i meant to say put them in cool tubes but alas.


    Screen of green eh? that has the potential to be a lot of work. How do you plan to do that? individual screens for each bucket? just curious.

    i've never grown on this scale but i really think vertical lights could yield as much or more than scrog. From what i read about g-13 it looks like a good candidate for kbs.

    but hey man it's your grow so have a blast.

    Too sweet R/X ,
    You got no idea how long Weedhound and I have been waiting for someone to do a crazy monster W/F -DWC scrog . I thought Just -a- Seed talked for a few about a 1000w. hps cooltube scrog but you've got it topped maybe .
    I had visions of a frame like your talking and maybe a big ass piece of chainlink fence ?
    We'll be watchin
    Peace

    yeah when I say screen of green, I dont mean like a perpetual garden sea of green. I just mean that there is one very large 7.5x6.5 foot screen over the 12 buckets. They will all be harvested at the same time. It looks like a sea of green, like a bunch of small plants but in reality its 12 plants spread way out. Get me? You will see soon enough.

    xcrispi, Ive been waiting to do this for awhile and I am excited to have an easy way to control growth. LST is fun but only for a few plants, then it gets to be way too much trouble. Soon as I see roots coming out the netpots I will rest easy. Until then, I am always uneasy. The G13 are doing great, but my NYCD came to me really big and lanky and they are not fairing as well.

    I have thought about the cool tubes Cornelius but I figure if I am going to do vertical lighting, I want to do it without any air cooling. Thats the best way to do it in my opinion.

    Thanks for the kind words guys. I just got a new digital camera today so things should be coming in with much better focus.

    Ive had great experiences with these air diffusers. Generation II Sweetwater Diffusers, 2
    I pump a sonic pro 2.9 psi air pump through one of the sweetwater 9 inch airstones in a 10 gallon rez. Under a 1000 hortilux, a big bushy girl fed with good nutes,67 degree root zone, and that many bubbles, 2 inch massive colas are the result. Make sure to get the elbow MNPT fittings and Heavy set weighted air tubing doesnt hurt either. Peace

    I will bet any amount of money that an open air line will give the exact same results. Airstones are 99 cents. I can replace em anytime I want. They dont require cleaning, just replacement. Thats why I dont spend any money on diffusers or anything like that. I currently have been using the same airstones for a couple grows. Havent cleaned em. Still bubbling like mad. Frothy water. I am going for 4" massive colas.
