One week ago I took a DOT preemployment UA and a rapid screen pre employment UA at the same time, as in I took two cups in the bathroom with me. Passed the rapid screen and got the job. I'm already out in the field working that job and got a call that my DOT drug test had a problem and couldn't...

New to the ebb and gro system. Was just wondering with 55gal of RO water for a 48 bucket system, how many ml should i have to add to raise my ppm to 600. Im using canna nutes and was looking at their feeding schedule and according to their schedule it would take somewhere near 500ml but....it...

So hypothetically if you were going to start a grow op in a 3,000 sq ft warehouse with 30ft ceilings and around 2000 amps of available power, which grow method would you use. Money for equipment isnt an issue, im currently in possession of 40 1k lights a/c units etc. I already have my plans...

I am designing a new grow room. In the room will be 8 4ft x 4ft tables with between 15-25 plants on each table. My question is obviously 4x4 is a small area for a 1000w hps but if money isnt an issue which would you use? I dont want to have 1000 watters if they aren't going to yield much more...

These ppp plants are about 10 days into flowering after vegging for ~30 days. They are under a 150w hps and anywhere from 125-250w of cfls. The temp in the room never goes above 86, and there is co2 supplementation in the room. I transplanted these plants after a ph soil problem about 20 days...

I have been thinking about an overall general question about heat vs light. Currently i have a 150w hps flowering 5 ppp plants. Currently the temp. in the room sits around 78. I have the ability to add about 200w of cfls that i used to veg with. But the temp in the room rises to about 86-88...

Two weeks ago my plants showed signs of a ph imbalance so after some research i transplanted from MG soil to a better soil with a ph of 6.7. I watered them using water around 6.0 to 6.1 and they immediately showed new growth and started growing very quickly. 6 days ago i switched them to the...

I planted 5 germed seeds 18 days ago and I have been having slow growth, due to what I believe is a ph problem. I have the seemorebuds book and it talks about how the MG soil has a ph around 5. I have read that elsewhere on these boards as well. I was adjusting the water accordingly assuming...
