Neem oil is totally safe as long as you don't use it a few days before harvesting. Just spray the plants down with water after the mites are gone.

I've used dry ice but there isn't any way to regulate it. I would just leave about 20lbs in a cooler with the lid slightly propped open. I would replace it as soon as it is all gone. It's not the best way to add CO2 but it's fairly easy and cheap.

You CAN do it that way but I would just transplant them normally. I would only do it that way if I couldn't pull the plant out of the pot without damaging the roots that are sticking out.

No, not usually. T-5's usually put out more lumens with less heat. When it comes to flo. tubes, bigger isn't always better.

I don't know anything about that bulb but I can tell you a few things that I learned about flowering. The further along the plant is into flowering the slower it appears to grow. You should see a big improvement within the next 20 days but it'll be very gradual. Only in the beginning do the...

5x2x? So um, how much height do you have or am I missing something?

I started off very simply and ended with a pretty close setup to yours. I didn't have nearly enough ventilation but I made due by having the lights come on at night and the AC on full blast. It's great that you started off with such a nice setup. My system consisted mostly of a 400w HPS...

You can use the hps as soon as you want to. Start off with the light about 2 feet above it and then gradually lower it. Just be sure that the temp stays right and if you notice burning raise the light back up.

I had always used tap water but I used a tds meter. The water was about 380ppm but the pH was almost at 7.0. I mostly used Fox Farms products so the pH was just right after getting the ppm correct. I used 800-900ppm for plants in soil and about 1200ppm for the hydro. Then again I raised or...

Do you have a fan blowing air across the plants?

If you have to, it shouldn't hurt. I've started flowering my plants anywhere from 6" to a foot without any issues. I beleive that the 6" plants had only 3 pairs of nodes. Some were in soil but most of them were hydro. For the hell of it I think I flowered some 4" plants and they turned out...
