6ft tall x4ft wide x 1'6" deep HELP

thats wat im workin with i plan on using CFL'S. i wanted to get 10 of the 23 watt 2700 lumen and 10 of the 60 watt 6700 lumen? i dunno the exact wattige and lumen...oh and i planed on having them on y-splitters or something...and how many plants could i fit i plan on having short plants maybe in red plastic cups i dunno yet

k so you want 10x23 watt and 10 x 60 watt = 230 + 600 = 830 watt....

do yourself a favor and buy a decent 600 watt light. it will cost you a little bit more but i guarantee you will be 100x happier every grow from this one on

23 watt are around 1600 lumens(70 lm/W). 42 watt is around 2800 lumens(67 lm/W). 65 watt is around 3900 lumens(60 lm/W). 105 watt CFL is around 6700 lumens(64 lm/W).

The lower the wattage, typically the higher efficiency. Down to 13 watts, below that it usually dips again.

Measure the cup's diameter, divide by the width&length of the grow space. Use that many cups. The more the better. Figure males and disease/pests will reduce your numbers by at least half.

You could probably fit several dozen 16 oz cups in that space. Just be sure to get the opaque cups, and not transparent cups. Roots die from direct light.

Realistically you could cover 4 sq feet of seedlings with a couple 42w bulbs, or four 23/26w bulbs(this would be better). Assuming reflectors are used.

ya i will be puttin some kind of reflecting material in there, any suggestions?...yes you are right i would love a 600 watt hps or something but i cannot get one so its outta the picture...TEATREEOIL wat do you think would be an average yield off a little plants like that considering the lighting i want?

hey do you guys think a 400watt hps would be too hot for this space? also im gna have a 400watt mh

i wouldnt say so man its a pretty decent size space.what fans do you plan on using?

ya u deff want to use fans...and when it comes to yield. it depends on more than just lighting. Nutes,soil,water,ph,strain, position of lights...all kinds of stuff all affect ur yield...and also it depends on how many plants u fit in that area.

If i were you, i would either use 2 150w HPS or 2 250w HPS. I would also make 2 DIY Cooltubes and have them in-line with their own fan.

You can get the Pyrex bake-a-rounds for about $15 bucks on eBay, and check stores like home depot or lowe's for "outdoor security lights to get the HPS's.

That space is just too big for CFLs...

i agree that is alot of space...u prob wanna go with something big and nice. unless ur only gonna use a small area of that area to grow in.

Use CFLs for side lighting, but I'd use 2 small HIDs instead of on big one. Since it's not square, and most systems these days are designed for squares, you get better coverage with the same amount of light. More ideal for a SOG setup.

i was thinking to grow small quick plants in dixie cups n hopefully i would get pretty dense nugs from the 400 watt hps. i was talking about talking the hps out and putting the mh for flower, isnt that good?

Swap your HPS for MH during flower? or did I read that wrong I wouldn't do that, HPS is for flower & mh for veg. (course you can do both with either bulb but id stick to what there spectrum is good for )

ya ill second that usually MH are for veg and HPS's are for flowering the color spectrum of HPS's are more red which is what u need for flowering and MH color spectrum is blue...which is good for veg but double check the bulbs color temp and make sure.

ya i guess thats wat it was i had it backwards. wat do you guys think a yield would be of a plants that is vegged for 1 week then start flower? and consider they will be in dixie cups.

are you talking from seed? or clones? If there seed unless there autoflowers they won't start to flower for close to a month (or once sexual maturity is reached which can be less time on some strains)..

You should be able to fit a crap load in there. Yield will depend on your plant genetics & amount of light those babies receive. With a 1000w hps or son agro type bulb in a sog 1oz per plant is possible. (it is a mix bulb that is part mh & hps)

But genetics have a lot to do with it. 1 strain might yield 1/8 off a sog plant & another strain 1oz per plant.

i was thinkin seed. ya i wanted to grow flavors like mango, blueberry, purple or something

That was a suggestion to start out. Figuring half them die(by your or otherwise). That's 2x the space for new pots to transplant into. But having as many as possible initially will ensure as many as possible choice plants make it to flower. Which could increase yield significantly.

Use CFLs, screw HPS or MH. If your going to do small plants, CFLs are able to provide more than enough light. With CFL's you you have more control over the placement of your lights, you can create a canopy of lighst and just flower way more smaller plants, you'll still get dense nugs and high quality if you do it properly. You would get more bud with HPS but, your initial setup will cost at least 3 X more than HPS, and you should be able to do it with less watts, saving you money in the long run.

TeaTree, sounds like you know your shit. I'm interested in what you were saying about the smaller watt CFL's being more efficient. I just find it hard to imagine. The amount of lumens they put out are greater per watt, or whatever, but don't you want that power so the light can actually immerse the plant. Personally I recomend to stay away from 23 watts and less, just because I find plants need to be within about 3 inches, or less. I'm not saying your wrong, just curious. Do you personally have lower watt bulbs?

i have 23 watt bulbs...12 of them...and my plants seem to be doing okay. alot of the problems iv had hasnt been because of my lights but more of me screwing up...iv heard what he said was true...but im not sure yet either...ima bout to order some high wattage bulbs cus i cant find any around here and see how it goes. but i would see what hes saying cus like ur adding a whole another bulb instead of having the same amout of power in 1 bulb...so naturally u can place them in different areas better. letting u spread ur lumens out well to cover ur whole plant because some parts of ur plant cover other parts. so if u think about 1 spot on a plant...where if u had 1 bulb no light would get to it because light is coming from above it. so then u have another bulb sorta on the side and then that 1 spot now has light. so in the grand spectrum of it...if u have less bulbs at higher wattages then ur covering less area of ur plant with light..whereas if u have the same amount of watts in lower wattage bulbs u can cover more area. I dont know if im making sense here but what do yall think?
