lighting

Figure 75-100w per plant when using HID lighting, which you should.

 

And what would be minimum required wattage for CFLs ?

 

I would go with at least 100 watts per plant. you can get results with less light, but your yield will be diminished accordingly, and it will take a lot longer to get there.

 

Hi, I've just installed this...





...works out at 125w total, which I've been assured is enough for two plants in a small space - I've set up a micro grow of about 70cmx70cmx70cm.

Very pleased with the unit (shade and 125w blue GrowKing Lamp) - ordered from Greens Horticulture in Bristol and came in at under £45 including postage (arrived the next day).

Screwed a couple of cup hooks in and used two plug chains to suspend it and allow for adjustment as my babies grow.

I'll see how this goes.

 

Really, so using 400 Watt HPS lights that cost me 240 dollars is excessive for 5 plants?

 

Different lights though - everyone says HID lights are the way to go, but as I'm growing very small and intend to LST then I'm happy to keep the wattage down by using CFL. Guess that makes sense?

 

Im just looking for the best deal here. Im going to Home Depot today Im going to ask for 200 Watt HPS and 200 Watt HID.

 

everyone has to work within their means. I don't knock anyone for whatever attempts they make. I'm new myself, and am building lighting as I can afford to.

for my first grow I used 160 watts of flouros on top and 100 watt cfl for side lighting. vegged for 7 weeks, flower took about 16 weeks and I got about 1/4 oz per plant.

2nd grow vegged for 4 weeks under 160 watts of flouros, and flowered under 400 watt hps. I'm 9 weeks in flower, harvested 2 already, 2 to go about 1 more week. first plant about 1/2 to 3/4 of an oz. 2nd plant about an oz and 1/4. the next 2 will be 2 plus ozs each.

each grow was 4 plants, all other conditions besides lighting and time I started 12/12 were the same. I used one of the worst possible mediums in my ignorance so future grows should put these results to shame, starting a hydro grow in a couple of weeks.

hope my experience is helpful to someone, peace

 

an hps is an hid my friend. imo, home depots overpriced hids aren't the best choice. you can find much better deals on line. I do like their flouro fixtures and flouro bulbs.

 

Well said SmokinJoe, I've noticed on this and other forums loads of people like to knock others and criticise - I'm just doing my best within my means and for my own enjoyment. I'm not running a commercial grow, purely for my own pleasure and enjoyment! I'm going to try a grow with what I have and see what it produces, if it doesn't deliver X volume of bud I'm not going to go out and commit hara kiri!!
