Exhaust should be able to completely replace all the air in your growspace within 15 minutes. If your room is 8x8x4 you have 265 cubic feet of air. Venting your growspace completely every 5 minutes is preferable, keeps heat down, gives more breathy shit to the plants. A 50CFM fan will replace...

Reefa - Neem oil is the standard treatment for killing spider mites and fungus gnats. Just killing only the adult creatures won't do it, you have to go after the larvae and eggs as well otherwise they'll just come back. Neem and a bacteria called Bt destroy fungus gnat larvae and eggs. Use a...

Sup dude. Get in your bunker cuz I'm about to drop a bomb called knowledge. "Bacillus thuringiensis (Bt) - is the best known of several bacteria that are fatal to caterpillars, larvae and maggots" "Neem - Most effective against caterpillars and other immature insects including larvae of...

Don't reuse soil. -High Times -Jorge Cervantes -Brown Dirt Warrior They say adamantly to not re-use your soil. Anyone can argue that you can re-use soil. . . . . . but you're going to argue with those names? I'm going to say they're right. They say don't ever ever do it because of bugs, fungus...

Wide spec is giving exactly that. A wide spectrum of light. Its putting out what your plant needs, but less because its producing other types of light. Your plant can't use the middle range of Kelvin, and energy HAS to consume wattage. If your bulb is throwing out 4000 kelvin range, thats energy...

Listen to the smart people lance. Don't grow 2 root systems together. If you want to use the same tub/pot put some kind of divider in, you won't regret the decision. Sift/mix the dirt while its wet, look for dry clumps. Happens ALOT with cheaper soil and dry pockets won't leave. If you don't...

Um, yeah buddy thats an air filter. A window unit blows outdoor air into your house so of course it has an air filter. WHERES THE EXHAUST?!?!?! Unless you have a real crappy AC unit cold air should be coming out there. Is exhaust cold?

Those are wide spectrum bulbs if memory serves. Is there a specific Kelvin range listed? Check out the CFL subforum on the "indoor growing" board, that is going to give you the information you need to get weed from your plant.

Without a picture I don't know. I think you're saying the growing tip died? I had a few newly rooted clones under a CFLs and one bulb slipped a bit and burned the top. The first section of the growing tip was brown and died. Is it crispy and is there a green center? I watched them for a bit...

Rubbing alcohol and epsom salt, cleans pieces like a dream.

https://www.rollitup.org/newbie-central/247213-cheap-easy-zero-mod-closet.html Hang your reflector with chain. Find a ceiling stud and drive an eye bolt, loop the chains through it. I grew in a closet similar to you once upon a time, I think the link above will be really helpful. At least it'll...

I used to smoke rez. . . . in a day long past. That shit is gross dude, throw it away.

Mike, people do 16/8 14/10 12/12 over the course of weeks when they are easing plants into flowering. If you have finicky sativas its usually a good idea, you add 1-3 weeks on flowering but plants reach better potential. Moving your light to 10/14 near the end of flowering is supposed to improve...

Wanted to check your journal before it gets deleted. So you know, males usually look like glorious plants because they normally grow more vigorously than females. When I throw bagseeds outside for shits and giggles I rip the huge ones early, they're always males.

Hey Kode, When you're not busy spamming bad information could you tell me where you saw an air conditioner with an exhaust filter?

AC exhaust? Does your fridge have smelly exhaust? Your AC drips because the cooling coils collect condensation. An AC unit is just freon with a condenser and fan. Peace

If you're doing HPS I'd just flower right away. Vegging to a foot or two is easy with a few CFLs, its less money than buying a 400W MH bulb (I'm guessing your ballast is electronic) Another option is to buy a Son Agro bulb, its a 400watt HPS that has an extra 30 watts of blue light incorporated...

Jorge Cervantes says only remove leaves that are over 50% dead. Your leaves are hurt, but still alive. Leave em on. I think I'm seeing leaf curling due to overwatering. That would really make sense to me, time release MG releases nutrients every time its watered. Green won't be burned by MG if...

-Buy socket splitters for your shoplights, they're 55 cents and saves you 6 bucks on another fixture. Double your lights. -Buy a inline booster fan @ home depot, lowes, etc. They're 20 bucks, far less quality than an inline fan but you don't need quality. Put the inline booster fan in the center...

Length of veg doesn't matter. Expect your plants to double in height during flowering, start when half your space is used up.
