Is this at your parent's house?

Hi I've been growing in my closet now for about 2 months without any security worries.I use one light (400W hps). Last night I noticed a helicoper flying over my house multiple times for about 20 minutes. I do live in a busy area in the UK close to the city so I figured it was nothing to be...

Inline fans can range in terms of noise. You can pay more for silent ones. I use one of these with a silencer: http://www.aquaculture-hydroponics.co.uk/product.aspx?productID=237&categoryID=8&subCategoryID=224 It's in my bedroom in a small wardrobe and I can sleep with it fine but it...

To thrive your roots need access to oxygen just as much as water. For this reason it is necessary that you adhere to a wet-dry watering cycle: Day 1: Water from top allowing a run-off from the drainage holes. Day 2: Let dry Day 3: Let dry Day 4: Check and water if top few inches dry, not...

Sounds like you're ready to get started!

If you use a vent cover for your intake it wouldn't look as suspicious and you can run your exhaust out the top like this: Can't take any credit for this though, It's somebody else's!

Thanks UF, I hope you found it useful.

Hey everyone, I found this awesome video. It's excellent for anybody wishing to build a large, purpose built indoor grow room. Takes you right through from preparing a room to harvesting your crop. Best I've seen yet. Online Video: How To Grow Cannabis 'A Dutch Video' | Veoh Video Network...

What's the temp?

He means he topped his plants to promote shorter, fatter plants.

Very good start for those wishing to get a bit deeper into the physics of growing. I suppose a next step would be to prove how the grow bulbs we use relate to the sun's photo properties and in turn how that affects plants.

Cheers man, I thought it'd involve some corners. Time to get the saw back out I'm thinking. I definitely want as close to 100% lightproof as possible. Peace.

Just out of interest, I thought everybody could post in this thread to say what strain they are growing at the minute. And, also post a couple of pics to see how it's going for them. I'll start it off: I'm growing Sensi seeds' skunk #1 at 4 weeks vegging.

Yup that does sound like a good idea. The only problem is I'm quite limited to space in there and not sure if I could fit it all in. But it's something I'll do when I get a bigger cabinet. Greg green says in the Cannabis grow bible that the room must be completely lightproof during flowering...

Yeah seedless that made perfect sense I just wasn't aware it happened. I'm not sure about the cooltube idea though. Have a look at my current ventilation: Sorry about the annotations, I hope they aren't patronising. I just wanted to show exactly what was what. I was just trying to...

Thank you seedlessone, I will try to bring that tube down like you say, It might be helpful if I stick an oscillating fan in there too. Sorry can you explain what you mean by alternating nodes? Yes, I was going to start flowering when my plants were at 30% of my total height . They are...

Hey This is my second grow. setup: Closet grow with air cooled 400w HPS, 100mm RVK fan+carbon filter, passive intake. Using 6x3gal pots with my own compost/perlite mix. Canna terra vega+bloom nutes. My plants are vegging and about 4 weeks old from planting seed. The seeds were...

A bleach is anything which 'bleaches' something and usually refers to a mixture as in domestic bleach. There are other types of bleach too such as hairdressing bleach which uses H2O2 (hydrogen peroxide) as a 'bleaching agent'. Lots have chemicals have other names depending on their intended...

To quote: "[the plant] should flower and display its sex — however the plant must be mature enough to present its sex. An immature plant will not show sex because initial calyx development is not photoperiod-related. Plants normally mature around the forth week of vegetative growth because...

Do you want to use a whole room for one plant? If you can't afford a HPS lighting system then go for CFLs. Major toke has had some great results flowering with CFLs. Place multiple around the plant. I assume the fan you are referring to is an oscillating desk fan type? If so this will be...
