This is my first try at hydro i grew in soil for a while. I have 12 drip system the pots are only 3 inch. i grow under a 600 hps in a 4x4 area iam growng white rhino snow cap and blue venom. I would like to get at least 2 ounces per plant. Is it possible in 3inch net pots.
My first hydro grow.I have a ebb and flow system,plants in rockwool and hydroton rocks in 6' pots.The plants are ak-47/lowrider fem....I have a 400 watt mh light and am using sensi-grow and bloom for my nutes.My main question is how often to feed aday...They feed for 15 or 20 minutes when on.Any help?

That depends on how big the plants are. If you've had them in a seperate veg room and they're ready for flowering, you can water 4-5 times a day during the12 hr light period. If they're new babies and they're staying there from start to finish, start with once a day and watch for droop. When they request more water, give them another feeding . . . and so on.
6' pots huh?

Thanks Gator, those pots you're using are the exact same ones I used for my first grow and the roots ended up very tightly packed in, unless I let the plants grow too tall. How long/large should I let plants get in this thing, last ones were cut down at about 3.5ft tall.

im having trouble with mine. i bought a 2000 dollar system and the temps are getting pretty high. if i keep it closed i get around 88 and if i open it, im only getting down to 78. That is with the lights on. when lights are off i can get it around 70- 75 which is all good... i have my a/c running fool power and it is 67 in the house. what can i do to control temp with it closed! i cant keep it open

Need a little more info. Do you have an enclosed light hood? How big are the exhaust and intake line? Do you have a fan on the intake? What "system" did you buy for 2k?
Get that heat down FAST. Keep an eye on your humidity. Mold can develop rapidly.

They will survive at 88 degrees. It's not ideal, but it will work. I've grown in warmer. You may also want to just add Co2. It will help the plants deal with the heat and grow with more vigor anyway. Win-Win.

No it's not ideal at all. If you're seeing 88 when it closed on a normal day, you'll easily see 90+ when it gets warm outside. That kind of heat causes the humidity levels to skyrocket. MF'in Mold!
If Co2 helps solve that, wonderful! I'm not running it YET, but I will be very soon. Most important, make sure you're using an air-cooled hood and you've got a good source of fresh air.
This is not a cheap hobby when you want to do it right.

What difference will it make what temperature it is outside? He's stated he's running his A/C and keeping the room it's in at 67 degrees. I'm assuming (because we don't have the information yet) that this $2000.00 is self contained - closed unit.
There are a lot of ways to get temps down and they should be kept reasonably low (mid 70's), but the range for growin really is more like 72-90 degress.
I would stop running your household A/C at full blast to keep the temps down. You may as well go out and buy weed then. You're cooling an entire home because you need one little space cooled. Get an A/C unit JUST for this.
And please post more info about your setup so we can have a little better idea what options you may or may not have.
Pictures would be ideal as would a link to the MFG's website or an online retailer who sells it.

I haven't seen any $2k self-contained units. I've seen a lot of tents though, and you can easily spend $2k+ on accessories. Waiting for more information.
This is a hydo thread, so I'm going to assume that's your plan of attack. What stage of growth are you in?

Hey what up everyone, i've been wondering about this question is i change my res every other weak; i always add water to the res every day when i see the water level has fallen, is this a terrible mistake on my part? Am i diluting the nut solution? Should i not worry about it and just change res every other weak like i have been just don't add water during the weak. Any help would be appreciated

Posted by laserbrn:
When I start from seeds I feed them PLAIN water for ~ 2 weeks. By then they are on about their 3rd or 4th set of leaves.
Veg feeding Schedule looks like this....
Week 1: 0 ppm
Week 2: 0 ppm
Week 3: 200ppm - Start the 3rd week with 50ppm. Increase by 50ppm each day until 200ppm is reached.
Week 4: 200ppm
Week 5: 300ppm
Week 6: Increase by 100ppm each day until you reach ~600ppm.
Week 7: Flowerin' time. Whole different schedule.
Some people like to pump the nutrients faster, but if you look through all of my past grow journals you will see WHY I do it this way.
Now, this is a basic guideline for what I would call "safe growing" and a good start for a first timer. This is a minimal feeding schedule and will should give you healthy plants, but not all strains are created equal. And that's where things get interesting.
Using this basic guideline I can work on determining my plants needs without risking burning them and slowing my progress.
I am looking for these indicators in veg:
1) PPM is rising as the water level drops - Too strong. Need to add water and lower the PPM. The plants are taking up more water than nutrients.
2) PPM is falling as the water level drops - Too Weak. Plants are taking up more nutrients than water. Need to add more nutrients to keep the plants happy.
3) PPM stays steady as the water level drops - We are in the right zone.
That again is another basic guideline, I then have to look at the plants....
1) Lower leaves are starting to yellow and overall the plant looks a bit "pale"
-Pleant is underfed and she would really like some more nutrients. Don't need to be drastic, she's just a hungrier breed.
2) Plant is REALLY dark green and starting to get "The Claw". The leaf tips are beginning to curl under. - She's overfed and has too much Nitrogen. Back off the nutes for a little bit. Overfed plants aren't happy.
You'll get the hang of it over time, but it's best to start out with less.
Recap: Change your water every 7-14 days (depending on the size of your reservior). Small reserviors need to be changed more often. Get a TDS tester. This measures the ppm (parts per million) in your recipe. Watch the levels and adjust according to your needs.
