Thread: a light question

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

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????

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

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.

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

Noob's guide to growroom set-up : a work in progress

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

ok so movin into my new place sooner than expected so gonna start puttin stuff together real soon. 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) 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 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

I highly reccommend Fox Farm. They are organic-based, not organic. Pretty much the same, but not quite.

NO!!! Don't kick em in the blooms! J/k felt the smartass comin out in me, sorry.

Either nute choice will do you fine. As far as additives--pick your poison. All I'm using right now is Earth Juice Catalyst with me adding extra molasses. Seems to do the trick for me. Also, just in case you were wondering, there is no one-absolute-best bloom booster. Some might be better than others, but the fert competition is fierce. Good news for growers! So again, pick your poison there as well.

Keep us updated!

firstly think i'm gonna go with foxfarm nutes if i can get my hands on em cheers opie

and cheers also for the heads up on the bloom booster pro gro all info shall be rewarded with pics along the way
was just tryin to have a sneek peek in the cuboards of the pro's

Glad to assist....

ok so just got the go ahead for my new place and as soon as i renovate the place im good to start.
so another few questions bouncing around in the brain firstly, will a standard bath room extractor fan be enough to vent my grow cab through a carbon filter?
second, is a passive intake (just a sealing flap on the side) ok to use in conjunction with this.
cheers guys and may plentiful bounties be bestowed upon you all

Can't you get an inline for similar cost...compared to the bathroom fan? The reason I ask is all the "fart fans" that I've had to turn on (lol) were loud as hell. I would think almost any inlines would make a more manageable humming-type sound. For the record, I don't use inlines. I run dedicated a/c (since there's 1600 watts in there as of today).

But anyway, back to your question...unless you have one on hand already, making it free---I'd look for an inline. Most cabinets need waaaaay more ventilation than they get. Look up the image reaper, he's been runnin a cabinet for a good while. He'd be a good person to ask ventilation questions to.

Good luck!

Unless your grow is about 2 cubic feet, and you use one CFL, you'll want something bigger than a bathroom exhaust fan. And that's not even counting using a carbon filter. Don't even get me started on HID. And inline fans are quieter.

ok so another decision made looks like its an inline fan then so any toughts on a passive intake?
plus i know it prob belongs in another forum but i picked up some bubblegum seeds by serious seeds, any1 used these or got any feedback on them?

Ideally your intake should be located in the bottom of your cab. or as near the bottom as you can get it since the air near the floor is usually a few degrees to several degrees cooler.

Serious Seeds seem to get a good rep whenever I see them mentioned. I have not ran any of their stuff. But for what its worth, whenever I decide to run AK47, it'll prolly be their's unless my grow bud has some seeds at that time.

Marijuana Seeds (cannabis, pot) shipped worldwide is really good, but a little on the expensive side.

Also, Buy Marijuana Seeds and cannabis seeds from Holland - high quality marijuana seeds (cannabis seeds) seem real good and less expensive, but I've never ordered from there. I may try them soon.

man this shoppin list is gettin bigger. my tds meter just arrived and i tested my water.
8 4 0 p p m cant believe its that high, but such is life so guess i'm shelling out for a r.o. filter. so does any1 know where i can pick 1 of these up for a decent price and also what kind of spec do i need. cheers guys.
peace out

cheers pro grow, and opie. its brilliant to have the availability to draw on the experience of others, and feel confident in doin so after reading ur previous posts.
cant wait to start putting this together but its gonna take time as its not top priority but at least its lettin me research and lets me sort out the best set up for me to start with.....
thanks again ppl

No problem glad to help.

ok so this 1's an opinon call i guess but said i'd just throw in the question.
im livin in an apartment block and the room i'll have my cab in has a window and on the opposite wall there's hole into a vent system which coocker hoods and bathrooms etc are vented into if ya catch my drift. it would suit my room set up better if i could vent into this duct but if you's recon this is a bad idea i could redesign and vent out the window.
in our new place i've been given 1 room (small) to have as my own. in here i intend to have a bar, my well disguised grow cab, my fish tank and all my photo's from home etc. so i'm plannin this down to the inch if ya know what i mean.
cheers guys and have a happy day
