Have 8 plants that are starting to have light green to yellow new growth and the oldest leaves on the bottom are yellow with green veins and dying. On the most dead ones, it seem the veins toward the tip are no longer green. My best guess is that they need magnesium but this is my first grow and...

Ended up going with the attic. Used thick painting plastic to section off an area about 3.5X5X4.5H, with a pop-off sealed door. Put in a 400W hps. put one fan venting air out through a vent in the roof then another sucking in air through 6in ducting that is spliced into the house ac duct just...

nothing, huh?

That makes zero sense...

Same here. Soil might stay slightly moist but I only water every few days. Its only on a couple leaves and they seem to be groing fine otherwise.

These ladies are about 3 weeks from seeds. They are fem WW in 2 gal pots with miracle grow soil. I have 8 total but 2 showed these signs a couple days ago. Doesnt seem to really be getting any worse or spreading to other plants. temp is around 80F under FLs with makeshift tinfoil reflectors. It...

Have already started but I think it may turn out ok. Problem now is that a couple of them are getting some weird marks on them. they look like very tiny rips through the leaf. gonna go read up...

Hadnt thought of that...

would prefer not to spend much other than lights and nutes but am willing to give them plenty of time. attic is pretty much the only option. shouldnt be too tuff to get stuff up there, just dont know about the heat in a couple months. also will prob only be able to check on them once a day and...

Im thinking something like this. Im just gonna section off the attic to make the room so it could be comparitively bigger so that I could have fans inside and wont heat up as much but still have smaller overall inlet and outlet air. perhaps an inline instead of the fan.

Ive thought about this but most ive seen are fairly expensive, at least $50. Id like to use hps but im concerned about the heat up there. might not be so bad now but will be in a couple months.

Im also wondering if I could rig a small room up there out of plywood or somthing and use a standard household fan jimmy-rigged to blow air in a hole or tube in one side and out another hole in the other side. Then maybe put a bunch of ona in the outgoing hole/tube, ore a home made carbon filter...

Thanks for the advice. Im considering cfls now but im actually a little confused. I know I can use 42w spirals in a standard medium base but am I right that the 105 or 150w such as ecoplus cant be used in those? I would go with those if I could but seems a little expensive to have to buy...

OPH Wow! ok so I'm gonna have to do something about the smell for sure. Ive seen some of the home made carbon filter instructions, my only concern is the price of actually pumping air through them. Any cheap suggestions? Szech I dont know much about power bars. Where can I get them and at what...

thanks for the reply. How do you have yours set up? I wanna say our attic is pretty sealed from the house but has a few vent to outside.

While this is a nice thought, these rules are FAR from basic. Though many scientists believe xx/xy is the type of system responsible for sex determination in marijuana, many others still disagree. One thing is for certain: sex in Cannabis is strongly influenced by environmental factors. This is...

how much noise do the HPS make?

Thanks. Yeah, keeping it pretty quiet. The only real closet space available is about 3.5ft x 4.5ft. but its a sliding door. might have to see if I can do something there...

Hey, guys. First time growing and first post. Just started and Im in need of advice on a few things. Let me explain my situation. My roommate and I decided (originally for fun) to do a grow. We've got 8 fem. white widow going. 5 are a little over 2 weeks and 3 are about a week behind. The...
