Id say dubious06 answered your question, but even with holes, you can still kill a plant by overwatering it. depending on your soil mix, it could retain water. And if it doesn't drain properly and/or retains water, your water could have trace elements that could be bad or stunt the growth of a...

those look good. just remember your yields and veg time will be greater than indoor since your relying on nature controlling the light. but then again it could be less if you don't take care of them properly.

LuciferUk, how's your grow? I've been looking at Kannabia seeds, but haven't seen any true grows.

How are the plants doing? Id say your best solution is to get vented hood that you can hook up to fan to pull 80-90% of the heat away from the bulb and allow for better light placement and eliminate/minimize heat problems. To start, don't waste all that electricity on the 400w for the first...

you can always buy a fan controller that has a thermostat (http://www.plantlightinghydroponics.com/cooling-thermostat-for-ventilation-fans-p-1488.html). There a bit pricy, but due the the extreme cold you will be experiencing, it might be worth the investment. you can even get backdraft damper...

you will need at least 2 vents. 1 to allow air in and one to allow air out. if you do this, you still need to have cooler external air entering the bedroom and grow room. But this also depends on the size of the bedroom. if it's a small room, keep a window cracked or the bedroom door open.

the only way you can keep the same humidity is to have a vented hood so that you can have a separate intake and exhaust for your light. this will allow you to keep the same internal humidity (give or take a few %) levels as your external levels. A cheeper way to do it is to ad a bowl/jar of...

can you post pics?

fdd2blk, Nematodes is one of the people who commented in this post. as for "Beneficial Nematodes", they would only help if fungus gnats or other pests are present in the soil. the pot's do look large (I agree) but you can't tell how tall they are, it looks like they barely have any soil, so...

funny how people get all high and mighty around here. I'd say since no one knows your soil makeup, you could have several problems or just 1. Overwatering, PH is off, Calcium deficiency, Magnesium deficiency .... you'd know overwatering when you see it. the plant will begin to droop and if...

Depending on your budget and tent you will need: •*1 inline fan (Canfan, Eclipse, Elisent...) - I'd go with a 6" minimum for any of the the tents out there. the one you're linking to is really only there to help keep air movement up to speed. the CFM on these drop down to almost nothing if...

I would have stayed with the 400w. it cost a bit more to get setup correctly for that size of a tent, but well worth it if you want to cover the whole area with a respectable amount of light. Not to bash on 250W, but you won't get the same exact results or quantity that you would with the 400w...

I would say you should have gotten the CFL(s) yesterday. those girls are going to keep stretching. depending on your grow space, this can be a bad thing. They are looking good, just the low level of light the incandescent is give off will not do all 7 plants justice. They are spending their time...

any of them if you're on a budget. can you keep any of them cool and keep your room temps down? if anything you can find a few complete systems (hydroasis.com is one company that i can think of) from know companies if your worried about anything resinraider said.

well it makes 120cfm (you said you have a 120cfm fans on each side of the hood). Basically you're not increasing the speed of air, just trying to keep it continuous within the hood (120cfm) and being fed out of the exhaust fan. Basically your using 1 fan as a booster fan. if it is not a cool...

go as big as you want. if you don't have the proper ventilation you won't be able to control the temps of a 400 or a 600. So it all comes down to your setup, not just your grow area. Temp of air going into the grow room, filter CFM, fan CFM, Cool Tube/Vented Hood, etc... all these factors come...

that's a heavy scrubber. it probably weighs 10-20lbs. are you sure it's 80? you should be able to find a joist or support beam (stud finder) that you can put some eye hooks into and support it with cords. as said in other comments, higher up and directly above your lights will pull the...

you should be fine. just do a few temp reading before you buy this stuff. what ever the hight and low temps are can help with determining the fan. if you can exchange that air at about 200-250 cfm than you may see temps with HID lights (400/600) that range from 3-25 degree differences from...

you may just need to keep it in veg until you can afford to properly vent your grow area for flower. it will always smell, depending on how good your smell is, and those around you, it can be hidden for only so long when flowering. you can always donate the plant.

you'll know more in 2-3 more weeks, but also keep looking at your trichomes. You can also get a rough judgment based on the flower time for your specific strain. differences can be weeks or even longer (month).
