a light question

[sweetgreenbuds]

:smokin: ok so i just want some feed back on these enviro lites.
im thinkin of gettin 2 of the 200w as im really intregued by them after doin some readin.
I know they're cfls and most will say stick with mh/hps but apparently they have a higher lumen/watt output than other lites and the light it gives off is 100% par which is grat for plants, right??

and as they are cool running they can be placed right on top of the plants so the lumens arent lost over distance. so guess im just lookin for some feed back form people who've used them as im doin a small cabinate grow, and they sound perfect to get lots of light without the big heat build up.

as always thanks in advance for the great support
peace out:hippy:

enviror light are just a flat CPf thats all and the net is the normal watts I think its 18 watts.
Watts is watts and thats it when it comes to cpf.
Now normal tube florsents the exposed bulb to the plant is greater do to disign.
A fulll service ballast (not wattsavor ) a full service bulb ( not wattsavor)
You would see a better responce to use full service system.
And the bottom line , if you know what your doing is
Grams/watts/ months or 1000 grams/1000 watt bulb months If you get .5 grams per watt month you doing real good. Note time is part of the division.
Hids provide a higher output per watt of usable spectrum. Noting that if someone says Blue or red spectrum which is only part of the spectrum put out by the bulb.
If you doing it to have fun go for it, but if your doing it for product , pot. its totaly your thing.
The busted for having fun is the same as growing good size plants.

ok so i was goin to go for the 2x200w but after a bit of thought i think i'll go for a 400w mh/hps but will that be to hot in my 2'x2'x8' grow cab????

[lmdesade]

If you've got 8' of height, a 400 hps is a better choice. I like farmtek cfl's for growing mums and small flowering areas. Yet, If you have that much height, there is no point in using a cfl unless you are going double decker. Don't!!!
At 100 watts of HID per square foot, you can do some amazing work.

cheers man just got a case of the noobs knees if ya know what i mean. so as it stands im buildin a 2'x2'x8' cab from mdf, mylar lined, with a 400w mh/hps. a decent vent system, änd running dwc in a large container with 4 airstones and a seperate res to help temp and ph control also fitted with a circ pump between res and main tank. im also gettin a ph meter, tds meter and a temp/humidity monitor.
was thinkin of installin a co2 system but i've spent this months hobby cash. plus i'd like to see the results without co2 first so i can see the difference if ya know what i mean.

this is only my first serious grow but i no longer things by half and am researching every item b4 purchace. i dont plan to grow for another 3 months and then only plan 2 raise 1 plant but am spending the time scouring this site and others to plan and prepare every thing so its perfect in every way then thats a fairly good place 2 start from. i know im bound to run into probs along the waybut have massive confidence thanks to this site.

so thank you all for this much so far and a masive thank you in advance for all the help ive gotten so far and the help i know i'll need and recieve in the future. any feed back or advice as always is gratefully recieved:hippy:

With 400 watt HID lighting you will most likely need to vent to the outdours. Also the big fans to move air will not be stealthy, if that's important to you. What about odor control?

And by the way, everything will NEVER be perfect.

[sweetgreenbuds]

cheers opie exactly the feedback i need.
stealth is of some importance but not 100% if ya know what i mean. im thinkin abouta 4" duct comin from the cab to an inline ducted fan (can i put this in a styrofoam box, 2 keep sound down?) and at you recommendation i think i'll be then routing it through a filter block and then out the window.

if my unit is completely sealed incl the air inlet and im using the carbon filter how effective could i expect my odour control to be? plus any recommendations on fan size given the size of my grow cab and allowing for maybe 6' of ducting, i saw a formula to work it out some where in here but cant remember where.

stay cool all you beautiful ppl

peace out:hippy:

hey cheers for the link rhizome v useful. according to that link a 25 cfm fam would suit but the only 1's i cam find that small are pc cooling fans and i think i'd prefer something with a bit more beef so was thinkin of something along the following lines: a carbon scrubber at least1.5' long mounted on the roof of the grow cab with the 4" pipe connected to a bath room extractor fan which, mounted on the outside of my cab is rated at 90 m3/hr which roughly works out at (ball park figure) 40cfm. i think this should work out sweet.

on another point i'm going dwc and just went down the pet store and got my air pump and am a lil concerned that i aint producing enough bubbles. the pump is rated at 73 gallons/hour (275 l/hr) if any1's had any success with dwc could ya please post and just tell me the rating of ur air pump,cheers

peace out

[sweetgreenbuds]

ok so movin into my new place sooner than expected so gonna start puttin stuff together real soon:thumbsup:. the box will be close to the window, like 8", so was thinkin of instaling a regular extractor fan in the window ducted to a carbon scrubber mounted in the roof above the light.
the light will be a 250w cfl for veg and 400w hps for flower.
i managed to pick up some serious seeds bubblegum so im bouncing with exctiement.
and the last question(well nearly) is what nutes should i get, ive heard some people rave about foxfarm as its organic (i think:smokin and im all for that as i hear it also yields slightly higher. but im not sure i could source this as im not in a position to order it and as it cant show up on my cc bill so might have to go with gh nutes which i know are good and available:jointsmile: sorry im rambling but what addatives should i get with which nutes im still a little vague in this area, i know to keep it basic in veg just water for first 3 weeks then 1/4 strength nutes then build to full but i'd like to give them a little kick in bloom so any comments or links'd be great

cheers guys
