    Exhaust fan on 24/7??

    Also, don't bother running co2 at night time. They don't consume anything, through roots or leaves while they are asleep. Pick yourself up a cyclestat http://jonsplantfactory.com/products/day-night-periodic-cycle-timer/ and dial it down to the minute when you want your exhasust to turn on, and...

    Exhaust fan on 24/7??

    Ideally you want to keep your night time temps the same as your day time, maybe even a little warmer. Having your exhaust on 24/7 during night hours will help maintain that 50% humidity level. During day hours your your exhaust should NOT be on 24/7, especially if you are using co2. The exhaust...

    Show Off You're Grow Room

    Waste of space, you could cram so much more in that area, and the lights are way too far away from the plants. Other than that it looks pretty tuned in

    Main factors of growing dense weed - please share your secrets!

    1. Room environment: temperature, humidity, and air circulation must all be perfect so that the plants don't get stressed out. The happier they are, the better they'll do. 2. Light intensity: a 1000w will do better than a 600w. If you have 15 plants under a 1000w and 15 plants under a 600w, the...

    humidity advice

    50% humidity maximum, any more than that and you risk getting powder mildew. If your leaves are burning it has nothing to do with the humidity. If you can't reach the level of humidity you desire, go out a pick up a humidifier. If the room is too humid, buy a dehumidifier.

    How much does it matter if u dont change the bulb

    I change my 1000w's every 6 months. You can tell the bulb is junk when it gives off a white light, rather than the orangish colour they have when they're new.

    cutting fan leaves. yes or no?

    Its good to keep the fan leaves for the majority of the plants' life. I prune once a week, taking off certain fanners. Its a very delicate procedure, as taking off the wrong ones can greatly decrease your yield. However, taking off others can increase your yield because it opens up new pathways...

    why is my plant so short??

    The roots are trying to find the bottom of the pot. Instead of you having growth above the soil, the majorty of growth is happening underneath the soil. Not a bad thing, it only takes longer to grow. Once the roots bottom out, you'll notice quick sprouting growth and your plant should shoot up...

    Khool bloom VS cha ching

    Plants don't NEED nutrients to grow. They do a hell of a lot better with nutrients, but they won't die without them as they would without light or water. Also, I never said pruning will make a plant grow faster. Pruning to me, and everyone else I know, simply means to remove certain leaves as...

    How should I run my ne w awesome setup (schedule planning help)

    My setup works out to 15 plants under each 1000w light, so I don't think 10 under a 600w is too much. Also, I think you'll have less headaches if you stick to one strain. I wouldn't jump around with them too much

    Khool bloom VS cha ching

    Nutrients are only a crutch for your plants. Environment, proper pruning, and never letting your soil get too dry are the three main factors that are going to either make or break your plants.

    How should I run my ne w awesome setup (schedule planning help)

    So if I understand this correctly, your plan is to harvest every month. And every time you harvest, you'll replace that empty space with the plants from your veg room that are already 4 weeks old? Like you said, use the hydrofarm panel for veg. (I'd put 10 3gal pots under it). Veg for 1...
