This last grow I had a slight problem with mold. I think one of the (several) contributing factors was due to inadequate exhaust/filtration. My grow room is about 9ftx5ft with about 9ft ceilings. I have a 8" vortex fan exhausting air that is approx. 750cfm or so if i remember correctly. I...

yeah the bud and bud formation look normal. I will get pictures in a few hours when the lights come on. I stopped my oscillating fans for a few days while I was solving my PM problem. The trics are clear/cloudy so I know its got a little longer to go.

Thanks everyone- It most likely is PM then, because I had a PM issue that I just dealt with. I sprayed a few days ago heavily with serenade. That particular plant was infected with PM. Temps are 74 with humidity in the 45% range. I only water like once every 3-4 days and I am in soil. i had a...

I just started the 7th week of flower and I noticed a couple problem plants. The bottom of the plant and inside middle look great, nice and green, and smells sweet. the top of the plant does not smell pleasant at all. The bigger fan leaves are yellowing (not crispy ) and are all pointing down in...

Thanks for the advice, I was actually more curious If i needed any others fertz, or is this 1.8-.1-6.6 enough.

nute help, Im bout to feed, thx

Do you have pics of your mg deficiency ?

My girls are in veg, and most are getting close to 8"-10" tall. Im about to transplant into 3 gal soil buckets. Right now they are in pretty small containers. I have hardly given nutes at all (foxfarm ocean soil) , until a very light feeding this last watering. new growth seems almost neon grren...

which of the 3 options would you choose? Next grow I will add (1) more 400w as these produce ZERO heat.

Right now I have 24 girls under (1) 400w ceramic metal halide. They are taking up a space of about 2x2 currently. At what point do you think I will need more light, or do I already need more? This light has a broad spectrum, but i am worried about the lumens, as it only puts out about 40,000...

Regular tin foil- Brilliant!!! Its cheap as hell (recycled is omly $1 for 25sq ft). I cant beleive i didnt think of that lol.

No white actually?

Yeah, i used the cheap $2 per roll duct tape and it was very helpful at identifying the cracks of light, lol. Its just too thin to keep out light, but i figured with the caulk already it would be fine. I will most likey just use the foil tape, it just a tad expensive so i was going to see if...

I built my room in the garage using 2x4's and drywall. Unfortunately, neither the ceiling, or the floor was level, and after i put up the drywall there were a few spots with light still seeping through. I caulked the top and bottom of the room where the light comes through, but the caulking is...

This is a ceramic metal halide that connects to a hps ballast http://www.hydro-techn.com/seattlehydroponics/ceramic.html This bulb was recommended to me by my local hydro shop for veg. Last run I used a 1kw HPS hortilux eye for veg because i did not have $ for a separate veg setup. Everything...

I need to replace my Hortilux eye 1000w hps. I do not have a separate lamp for veg, my last grow i just used the hps for veg and flower. I was wondering how these dual spectrum bulbs are, and if anyone has used them? They combine both enhanced M.H. and Super H.P.S. to achieve strong peaks for...

Im in the same boat- I have 1 light, and I am hoping for 2lbs. I plan on vegging 12 plants until they are about 18".

IMO you are going to need quite a few clones- 5 days is a very short veg. I bet they only get about what, 6" before flower? Seems like you would need like 30. I dunno, its all about genetics. Are you in hydro or soil? I did a little over one elbow dried with 12 girls under a 1K in a 7' x 2.5'...

Awesome, sounds good! How long do these charcoal filters last, about a year?

Thanks for the input- You think a 4" for intake would be fine? I think its only around 150-200cfm or so, or is that too big too?
