Update: Thanks everyone for your advice. I switched to 18/6 and saw considerable growth in just 8 days, more than 24/0. I'm a believer now. On the first of January, I switched to 12/12. Here are pictures as of last night... 1. Three of the four remaining plants 2. My best plant...

The soil is brand new. Why flush it?

I tried 18/6 one day and I switched back to 24/0 because the plants were sooooo droopy when the lights came back on that I decided to stick to 24/0. Do plants really need to so-called "breath"? I've heard people saying they vegged faster with a constant light source. Your results?

The plants were lined up 2 rows of 3 when they were in the cups. Like this: O O O O O O ...with a single incandescent 100W bulb hanging in the middle. I always rotated the cups, but the plants grew at different speeds. Should I put up 4 walls of reflective material for light reflection and...

I really don't think it's root lock. Here's why. I seeded them in styrofoam cups for 1 weeks w/ M.G. moisture control. Then, I tranplanted into 1 gallon pots with M.G. M.C.. I saw that the roots had already made their way down to the bottom of the cup. They grew in the 1 gallon pot for 3...

The attic is anything but hot. It's connected to the outside and it's very cold where I am now. I'm worried about my plants being too cold when I switch the lights to 12 off. (Like lower 50's) Should I be? I think the lower leaves shriveled when I kept them under the incandescent because...

... I have left to veg these bad boys? I germinated the seeds mid-November and kept them under a 100W incandescent bulb until the start of December when I switched them under a 400W HPS light system. Always 24/0. So, 2 weeks under 100W then 3 weeks under 400W HPS (w/ blue spectrum added)...

Why type of PH tester do you have? I like it.

Help me out guys. Here are today's pictures. The leaves feel kinda crispy. I've turned of the HPS light for now. What's could possibly be the problem?

That's what it is pretty much. I've also noticed the slow leaf growth. I don't know if it's the strain or my growing technique. Probably the latter. One small bulb is not enough for 6 of these babies to photosynthesize. Anybody have any recommendations?

That's our insulation. It's extremely shredded newspaper. :smile: The attic is about 75 degrees (room temperature), and it's well ventilated. I don't think that's the problem.

Hi everyone. I'm on my first grow and everything's going nicely so far. I germinated my seeds mid November, planted them in small cups with Miracle Grow Moisture Control, and let nature take over from there. They sprouted in a few days and I held them all under a 100 watt incandescent light...
