Thinking of starting a small weed grow (in Holland)

I want to grow a few (5-15) marijuana plants and I have some questions. Does the plant die after a single harvest? Or can I get multiple harvests from one plant? If so, how many times? Would one of these PURple lights be a good idea? Or is that a little over the top for a small grow? Would people in the area smell it if I hook the airflow up to my chimney? Do you recommend ordinary fertilizer or should you have special stuff for MJ?

you can reveg a plant after, i dont know how many times i have only done this a few times myself and each time i have revegged them once, i assume you can do it several times but its better to start with fresh baby clones (or seeds) instead of working with old grandma with a death wish
i HIGHLY recommend the lightening, im looking to invest in some nurturelite growlights myself one of these days,
I use a dutch brand called biobuzz for fertilizer, i highly recmommend that too, but there is plenty of good choices of fertilizer , and in holland all the best brands are availble, there is a reason i take my car and drive down to amsterdam everytime im ognna buy new grow stuff
people may smell it, it gives a good odor, there are ways around this, ie active carbon air filters

Thanks. Two extra questions: Can anyone post a picture of a male and female plant in the stage where the males haven't produced pollen yet? What is the average yield I can expect per plant?

I heard that plant loses some potency after third regeneration, but as always some strains do better than others. Try a few different strains. If the ht air rises out of your chimney, then there shouldn,t be a problem with smell. Make sure the rest of the chimeny (except top) is airtight if possible. I use canna coco a/b for vegative growth and ionic bloom and ionic boost for flowering. Also hormonal growth enhancer (super-thrive) and sea-weed extract throughout whole grow cycle.

Thanks for the pics.
I've read that cannabis grows in long straight stalks. But I've also seen pictures of bushy plants. How do I make them more bushy? By cutting them or something?

PURple lights will help keep temperatures down i small grow room. HPS is still recommended by most growers i know though. If you cut of the top of the plant when its on its 3-5th set of leaves it'll put all its energy into the side shoots. It all depends what works best for your space. If you don't want your plants too tall top them at about 12" wait a week and then start flowering, if height isn't a problem then just leave them as is and flower at 12". Topped plants need more horizontal space. About 2 weeks after you start the flowering cycle cut off all the stunted side shoots from the bottom of the plant, leaving only 4-8 of the most healthy looking shoots, this way you'll get maximum growth for these healthy shoots. Do this especially when regenerating plant as they can get way too bushy.

And for ventilation, what kind of pump would I need for a 2m3 grow cupboard?

For ventilation use something like this :- http://www.screwfix.com/app/sfd/cat/pro.jsp?cId=100593&ts=09155&id=71740
You'll need two - one to blow air in at the bottom and one to suck it out from above the light. Doing this with a oscilating desk fan to circulate the air should be all you need. And get a quite one. It'll drive you crazy if its too noisy!! (professional ones are available but at 3x the price!!) Carbon filter may be a good idea, see how it goes. Mine don't have too much probs with smell.

PS- using a PURple light will really help any heat problems. You still need fresh air coming in to the room at least 1/3 of the time(eg. 20min/hour). If temps don't rise above 25oC you could probably get away with more lighting. Your size grow space will produce maximum harvest with around 600w of light, but not if temperatures are too high. If ventilation is good 1xPurple light and 1 or 2 100w CFL lights should give good results - upto 20 oz!!!
Let us know what method you decide on and what your eventual dry weight is. If you get 1g/watt of light used you've done well.

or just use a blue nurturelite for vegging and purple and red for flowering thats what i want. Nurturelites are sweet,and much more cost effective on your electricity bill.

It's per harvest. Even if things go badly you can still expect 0.5g/watt. Its a good way to gauge how well your doing. I had a tiny grow room once with temps of 30oC+ and cheap nutrients, and still got 0.6g/watt!!! (600w light and 340g dry weed)

Wow, I'm gonna give a lot of free weed to my friends then 
How many harvests can I expect in a single year?

it depends on you really... if you have enough space dedicated to the grow you can astablish a cycle that produces a harvest every two weeks or so... depends on what you're looking to do really!
you should consider having sparate grow spaces for mothers (to take clones from) along with the vegging plants and a saparate room for flowering
if you have enough moms you can constantly produce clones and keep the cycle going...

I want to keep it to a single room and want to keep my energy needs low. I don't want to grow for sale, just for me and my friends. I'm thinking about putting one male outside in the garden and harvesting pollen. So I can do a seed run and store a lot of seeds for future use. Or would cloning be a better option?

cloning is the FAR better option IMO...
find a mother plant you like and stick with it... after a while you'll want to try another strain anyway so you get diffrent seeds!

Ok it would help if i knew what strain you are growing but in general total crop time is 12 weeks. You need 3-4 weeks vegitating and 8-9 weeks flowering. This means you'll get at least 4 harvests a year. Here's how you can make that 8-10 harvests a year without using another room:-
A shelf above the main grow area can be used to clone cuttings and germinate seedlings. It will allow you to double the area of your grow space and is an invaluable storage area for plant food, spray bottles and other gardening supplies. This area stays very warm, and no germination warming pad will be needed, so this arrangement saves you $.
Hang a light proof curtain to separate this shelf from the main area when used for flowering. This will allow constant lights on the shelf and dark periods in the main grow area. Velcro can be used to keep the curtain in place and ties can be used to roll it up when tending the garden. Black vinyl with white backing works best.
Now you need light. A couple of shop lights will be fine if you just want to start plants inside and then take them outside to grow in a small greenhouse. They can be purchased with bulbs for about $10 each, or without bulbs for around $8. Try to find them on sale. Use one Cool White and one Warm Light type bulb in each to get the best light spectrum possible for plant growth. Do not use expensive Grow Lux type bulbs, as they do not put out as much light, and therefor do not work as well in most situations (go figure). If Cool White is all you can find, or afford, use them. They work fine, and are by far the cheapest.(About $1-2 each.) SHELF GROWING
Shelf gardening with fluorescents may be the trend of the future, since the materials are so inexpensive, and easy to obtain. Fluorescent lamps are great for shelf gardening. In this system, many shelves can be placed, one above the other, and fluorescent lamps are used on each shelf. Some shelves have 24 hour lighting, some have 12 hour lighting (for flowering). Two areas are best, perhaps with one other devoted to cloning and germination of seed.
Shelf gardening assumes your going to keep all plants 3 or shorter at maturity, so all shelves are 3-4 feet apart. Less light is necessary when you have plants that are this short and forced to mature early.
One drawback to a shelf garden like this is that it is very time consuming to adjust the lamp height every day, and it is harder to take a vacation for even a week with no tending of the garden. This applies mostly to the vegetative stage, when plants are growing as much as an inch per day. Lamps on the flowering shelves are not adjusted nearly as often.
Normally, the lamps should be kept within 2 inches of the tops of the plants, with the plants arranged such that they get progressively taller as the end of the lamps go up, so that all plants are within this 2" range. This is an ideal however, and if you do go on vacation, adjust the lamps so that your sure the plants will not be able to grow up to the lamps within that length of time. If enough flourecents are used to completely saturate the shelf with light, the spacing issue will not create spindly plants. They will mearly grow a little slower if the lamps are not very close to them.
Source:- http://www.nirvana-shop.com/info_growing_guide.php
This shelf can go about 1m down from ceiling height and needs to be wide enogh to contain the pots your going to use. It shouldn't effect your other plants as they won't grow to this height(except maybe near the end of flowring for some plants)

Probably gonna grow White Widow. For growth I'm going to use an energy saving PURple lamp. It's 200W and is supposed to equal a 600W HPS light.
Your suggestion about a shelf for the clones sounds good. But I could also grow them outside the box with a small light. Clones don't give of a lot of smell, right?

Cloning is good but keep growing a few seeds to try and find your favourite plant to use as a mother. Not only do different strains have different characteristics but each plant is an individual. So genetic variation applies. Keep looking till you get a perfect balance between THC levels/grow time/harvest/disease resistance etc. Then clone this plant, give clones to other just in case your mother dies. There are also ways to get seeds on just one branch of your mother, check out the grow guide link in my other post here.
