for me, not using a computer to control my grow room is like using a horse and carriage to go to the store. no other way makes sense to me. I've seen a few other people online with similar interests in computers. post some pictures, show us what you created. take a chance to brag. I started out...

I was at walmart today getting stuff to change the oil in my car. I was waiting in line at one of the self checkouts when I look over and notice someone left $40 in the machine next to me. the people in front of me just finished, so I couldn't just walk over and use that one without it looking...

obama says no more pet projects. well wtf is this crap? is the military in a contest with nasa to spend more money then the other? $9.5 million dollars to research and develop a heat sink! are they reinventing the wheel or is it nuclear powered...

I've heard of doing this before, but a friend of mine told me he does it with good results all the time. does anyone else put their plants under 12/12 light for a few days just until they show sex, then move them back to 18/6 to become mother plants? I think I have mostly good quality genetics...

what is the closest to perfect way to germinate seeds? it's simple enough to do it the right way, but I recently found myself asking "what can I do to make it better?" I may have just gotten a bad batch of seeds, or maybe the conditions aren't perfectly right. I hope to clear this up then come...

what kind of growth rate are people getting with soil or hydroponics? I'd like to get an idea of how fast most people can get their plants to grow when vegging. I've been getting about an inch a day vertically in ebb and flow. how much faster can I get them growing in my next batch?

what does the exhaust from your carbon filter smell like?? when I first made mine and tested it, the exhaust smelled like carbon. I've been using the filter for a month or so now for veging, and I swear, it smells like fresh cake! it's a very sweet smell. do I not have enough carbon in my filter...

people who you only know online don't count, or we could all say hundreds or more.. so only people you know outside of the internet, how many people do you know who grow sweet mary-j? it started with hearing from one relative that another relative grows big time, high grade, then hearing about...

someone post a reply quick, I need to make sure I'm getting emails ok from this site. I moved to a new server. :bigjoint:

what are some of the worst growing ideas you've seen on rollitup? I've seen someone asking how to clone seeds, and people joke about using candles to grow. what about painting a room with glow in the dark paint? how is that for saving electricity. no bulbs needed, the walls will glow and light...

I can't be the only one who watches heroes. I don't see anyone else posting a thread for it, so here it is. so how was the first episode? it was pretty good. I wish I could remember more of it, but I know it was better then last season. what do you think is with niki? alive and with new powers...

my main grow is indoors, but I've been thinking about trying outdoors too. just plant a whole bunch of extra bag seeds in the woods and see what comes up. I haven't done much research on this subject, because I'm focusing on my hydroponics, but maybe I can get a few quick tips. there's my...

for some reason, I feel like I've seen this question asked on here before, but I can't remember. probably just deja-vu from being high. I had a cherried bowl that got soaked with bong water, then left to dry out. the ashes seem ok now, but it is really really strong. 2 tinny hits and I felt...

I have 2 small rooms, both 4 feet tall, 7 feet long, and 5 feet deep minus walking room, so total growing space is 4 x 14 x 3 1/2. I have an exhaust fan about 200cfm, with a 12x18 inch inline box carbon filter that I made. I'm starting out my first plants under 3 sets of cfl lights, 16 100 watt...

I'm putting together a computer controlled grow room. I already have a working prototype set up and working well for the last 2 or 3 months. here is what I have in the works. feel free to post your ideas or suggestions. the program is open source and free. you can get a full copy for free to...

I'm doing ebb and flow with earth plugs and fish tank stone. I have a dilemma. how do I flood the system often enough to keep everything moist, but not cause problems with the earth plugs? I don't want root rot right at the main root trunk, but if I keep the water level below the bottom of the...

I'm not a beginner, I have done professional web development for a company in the past, and still do it for my own projects, so this isn't a beginner question. also, I'm not looking to compete with rollitup. I like the site, I just want to start my own contributing website with information. how...

everyone needs to rant and release anger now and then. today is that day for me. post your rant for the day. fell asleep on the couch, overslept for work by 2 hours.. had a good sub from wawa, but now I have a head ache. stress from bills, misplaced an 8th of weed someplace in my house and...

I was brainstorming a little bit. I'll need a mini hydroponic system set up for mother plants. I thought about soil for the mothers, but maybe keeping everything hydroponic would be more consistent. here's my idea. not much water is needed for a top feed drip system. just a single small tube is...

I have some seeds started, but I was wondering if this is something I can do.. can I put the plants right into flowering light to weed out the males, then once they show sex, can I take clippings from them and put the new clones into veg light? would that be ok or would it stress the plants to...
