I'm a noob to hydro (except for all the reading I've done) so I put one of the long thin blue airstones in my 18 gal reservoir (for a flood table) like I was told. I've been reading everything I can find about the purpose airstones but I'm still a little confused. Pardon me if my questions are...

Well I'm planning to fit 24 plants in there SOG style so it could definitely produce a good chunk of bud IMO. I want to make it the best quality I can, so I have no problem implementing some CO2 if it is worth the investment. Am I likely to run into other problems when I seal the room? It...

Assuming I can keep the temps under control using a/c would you think the set up I mentioned would work out? Basically my main questions are: Is it possible to aircool the lights without affecting the CO2 level in the grow room? Do I need to bring any fresh air into the room or would maintaing...

Would the ducting I mentioned runnning through the lights not keep the temperature down enough? I was assuming that if I aircooled the lights it would be enough to keep the closet the same temperature as the room that it's in. I plan to have that vent sucking air from outside the room, through...

Thanks for the link. How would I keep my reservoir clean if I wasn't using H202? I have and airtone too, but if I go more than 4 days without adding H202 brown stuff starts growing in the water.

I'm using Pure Blend pro bloom. This is my first hydro grow so I'm just the nutrients that the guy at the hydro store pawned off on me. I just realized it says "premium natural and organic plant food" which concerns me because I'm using H2O2 in my reservoir. Seems like I'm probably not using...

So even with the venting you think that the lights will make it too hot in there? I thought one of the added benefits of CO2 is that you can keep the temperature in the 80's. To me it sounds like CO2 is more than worth it (people claim it can even double growth/yield). Or is it just plain...

I'm growing in a 5 x 4 x 10 foot closet. Right now I have one 2x4 flood table and I plan to add another with a 600W light over each table. The lights are air coolable and the only opening in the closet is a 2 x 8 doorway. Its a small space (~200 cubic feet) so I figure I'd seal the doorway and...

BTW I'm using a flood table if that makes a difference, and I'm using tap water which comes out at about 500 ppm (ECx500).

Any recommendations on what nutrient levels to use during the fowering cycle (either at 0.5 or at 0.7)? I've been trying to look this up but it usually doesn't say which measurement they are using.

I'm a little confused about which measurement people are talking about when they refer to the TDS in their reservoir. I am using the Bluelab Truncheon nutrient meter which shows the ppm in both EC x 500 and EC x 700, so I have two different ppm levels. No one ever seems to mention which one...

I'm trying to decide if it's worth it or not to buy a ph meter. Right now I'm using the general hydroponics tester kit for my hydro grow with no problems. I can keep my water at about the right ph according to their color charts. However, I've heard that these test kits are not very...

Just wondering how often I should flood my plants in sure to grow media and for how long (in both 12 hours of light and 24 hours of light). I've heard 6-8 times a day for 6-8 minutes but I don't know if that's for veg or flowering. Any other words of wisdom about the sure to grow media would...

Good point. Just hear a lot about keeping mother plants. Are they just for people with bigger grow rooms?

I want to use the sea of green method, so the clones will have no veg time (This is the way Al B. Fuct grows his). I don't think they will be big enough to clone before they are too far into the flowering stage. How big does a plant have to be before you can take strong clones from it? If I...

I live in california so I can buy clones from local clubs for around $15. My flowering room isn't huge (5X4) and I plan to have a sea of green type grow so I'll have around 16 small plants in that area. I'm guessing that'll be around $120 a month for clones (I plan one buying 4 every two...

Just wondering if there are any problems using rubbermaid containers as resevoirs. Its $90 for a 30 gal resevoir from my local hydro shop, but I can get a 30 gal rubbermaid container for $10 at target. Any opinions on the benefits of using commercial hydroponics products over other less...

I have been doing research for a few days and finding conflicting/unclear information so I am posting all the questions I have about setting my grow room(s) up. I am planning on setting up a flood table with a sea of green type grow. I have a 4X5X10 foot closet and a 3X2X6 foot closet to work...
