Hydroponics

hi i am use a dwc that i bought from homegrown hydroponics called a flower chamber i am useing rockwool in a net pot i was told the net pot end should be in the water is this right.if so wont the rock wool get to wet and drown my plant?also it has 2 vertically mounted cool blue spectrum 20w is this anuff can't but put flors over plants mounted on sides.thank you for your help sorry so long

Today is the 72nd day of flower... I am planned to clip within the next two weeks. Should I be extra concerned?

I was also wondering if the fact that I have no sort of CO2 intake to the room would have an adverse affect on flower density?

I'll try to get some pics to attach so you can see it.

Well then, I can tell that you are growing a sativa-dominant strain, if it takes 85 days to ripen. And they will fill out in the next 2 weeks. Sativa buds grow more elongated and stretchy, and tend to look kinda stringy compared to a fat, dense indica.

At this stage, you can only let her ripen, and harvest what she gives.

Yes, calmag and kool bloom can be used together.

Rockwool should be wet, and not allowed to dry out. The beauty of rockwool is that it holds a lot of air even when saturated. Those flouro tubes are not enough light.

out of curiosity, can you make a clone with a single branch of the plant with only one set of leaves?

That's how I take all of mine. Of course, I remove all of the leaves except the top 2.

thanks potroast why do i use cal mag/what is its purpose and what flors should i get

Hey Potroast, i am ready to plant my clones that are in 3" rock wool cubes into hydrotons and individual pots in my table. I have read that some people plant the cubes 1/2" above the flood plain and flood 3x a day and some say to plant the cubes so the flood plain soaks up to the center of the cubes and flood 1-3x a day and flood once a week from the top. Could you tell me which would work best in my flood and drain table? I am using a 400w Super HPS and CO2. You can see my set up in my journal.

hi potroast i saw Mr greens video he said he use's some kind of water that has co2 in it that he sprays is plants cents i dont have a co2 setup i would like to know what kind of water this is can you help"he called it bubbleing water"

Nearly got to be club soda. That is water with co2 in it. Dont taste too bad with some good vodky and a twist o lime neither.

i just bought some differint flors one is called sunshine from ge full spectrum 875 lumens the other is for plants and aquarium 750 lumens red and blue spectrum are these all right for seedlings and when do i swich to my 600w hps also should i use both kinds of flors or just one kind my cabinet was already built with flors monted vertically one on each side my cabinet is 3 ft wide 2 ft deep 4 ft tall

I was thinking about making a hydro system. Is it worth it?

Well I think it be ok if it aint too complicated..the po po's dont catch ya and your Mama dont find it. I would have a plan to keep the preacher outta the grow room too. Just trying to cover all the bases here.

I'm sure this has already been addressed, but how much do you think it would cost to build a hydro set up like the guy in the "I grow chronic" video? Not including seeds, those vary way to much to account for them.

how good is bat gano??

I always flooded up to the bottom of the cube, and drained immediately. You'll need to experiment with your setup, and make adjustments as you go.

Apparently, not very valuable to the bat.

Potroast...

I am brand spanikin new to growing (actually only reason I decided to grow is my old connect died, whatcha gonna do right?) So anyways I figured since I had to start I'd rather start with dro, but have been reading a lil bit and it seems harder to grow this way... would you say I should start here or not, and if so what would you advise for a newbie with a modest budget?

Check out the grow FAQ's, there are answers to so many of the questions that you will have at first.

Personally I am doing DWC (deep water culture) hydro and I was not a member when I started. There are so many things on the grow FAQ's and they are all divided up into categories so that you are able to get specific about your question. When you are having trouble finding answers there or want a second opinion on methods or processes described search threads and start your own to find other referance...

happy growing!

Always good advice to read up a lot first, but I always advise new growers to start with dirt growing. It is exponentially easier and will give you the best chance of actually harvesting some bud. Once you've harvested some bud, you can decide to try a more advanced growing method.

Dually noted Potroast... Thanks

New grower , with wilma 10 pot drip system ,canna vega,canna flores, airpump for nutes , nute heater , 600w grolux 200w cfl,40w grolux flourescent 4ft , tap water gives a high reading poss an 8 but i have ph up and down .
could realy do with some help on temp cf readings(what ever they r ) ph ,cf (cf whats it mean ) O and got a blue truncheon to test every thing . please help .

Recently I decided to upgrade from two 3'x3' tables to six. In the hopes of consolidating equipment and saving space I decided to use a smaller res with a separate pump and timer for each tray. This way I could get away with a much smaller res and wouldn't have to worry about structural support for the tons of water it would take to flood all the tables simultaneously. Hopefully I will be able to do more frequent reservoir water changes without wasting nutes as well. So I ran all of the drains to a single line and cut tubing to length for each table, the longest being 12 feet and the shortest three. Problems. Each table fill and drain in different amounts of time. So I decided to run a separate drain to the reservoir for each table thinking that the long drain tube and numerous tee sections where impeding the flow of water. So now I will have twelve separate hoses running to the reservoir. I need to make sure that each tray floods and drains in the same amount of time. What I am thinking about doing is cutting 12 hoses all to the same length, the length of the longest run needed and then coiling the shorter runs and ziptying them in a loop. Would this help to keep all of the fill and drain times the same?

As for the tables draining slowly, I think it may have been partially due do the tubing I was using. I was using black rubber hose with a relatively unsmooth inner surface. I pulled it all out and bought black flexible pvc. Hopefully the smoother inside surface will allow more water to drain quicker.

On another note, I attempted to fill my tables with lava rock and after unloading 300 pounds of it into the tables and trying to rinse it, I realized that it was just too dirty and gritty and would be causing frequent problems with the irrigation tubing. It only took me eight hours to everything cleaned up and the lava rock out of the op. Back to square one. So heres what Ive got: a bunch of plants in six inch rock wool cubes. Maybe I should just set the cubes in the trays and go without any other medium. I dunno where to go from here.

Wow, Seattle, it sounds like you should switch to decaf.

That coiling of the hose idea is wacky, and probably won't work like you think, but I got a good laugh about it. The only way that I know to solve the uneven filling problem is to fill them until each is overflowing. That means adding an overflow drain to each bed, and another drain hose. The overflow drain is set higher, so it only drains when the bed is full. Then the pump shuts off, and the rest drains out the low drain.

Rockwool cubes are not best suited for flooding, especially 6 inch cubes. If you simply put the cubes in the beds, and flooded, you would need to flood only a couple of inches, and only once per day.

You can reduce the amount of solution required to flood by putting "spacers" in the bed where you don't have pots/plants. A spacer can be a brick or rock, or a plastic container filled with water, anything that will take up space so less nute solution is needed.

hey potman listen..im doing this hydro unit with ebb flow etc etc and ive bought also the co2 tank kit as reserch told me it could be good for plants(ive tried the cheap baking powder method and it worked) so i figured i would but a good 1 for my big ass new room..could i use it directly in the water connected to the ph controller to mantain good ph levels??? , because i think (and also some have told me) that roots dont need co2 and it could be irrelevant to use it that way....
should i just diffuse it infront of a fan just to create co2 for the plant leaves
or should i 'waste' it on ph matter? (although i think ph is the biggest matter )

also i was thinking of buying a 3 slot nutrient feeder Aqua Medic : Freshwater Catalogue : Dosing : Reefdoser to brag about how hi-tech my shit is!!! (Actually because i suck in this shit and i want it to be easier for me since ive got a big budget to spend on something that might not yield!! lol ) would you reccomend it??

......one last thing , i currently am on the 3rd starting week of a single female plant its a white widow female sensi seed... when the leaf is small it has a rich green colour..then as it ggrows it loses the colour (as in light green not pale) ..is that why they call it white widow? or is it because ive got a problem???
