Hi Guys/Gals, Designing my new grow cab and stuck on lighting. My space is a fairly small closet that measures 53" high, 20" deep and 35" wide. I will be running a cool tube and as yet have not decided on a fan for the cool tube, however I will have a 120cfm exhaust fan for the cab and a...

No offence but it might be time to put those 'relationship pants' back on. it astounds me that these days men are submissive to their wives. yes a relationship is a two way street but i can never understand men always having to ask their wives for permission all the time. You should get a micro...

Hi All, After a 3 year break from growing I'm back at it. I have some seeds that are pushing 5yo and I've not had a lot of luck in germinating them (high failure rate). The ones that have germinated are growing at a snail's pace (i.e one is 1.5" tall and only has one small set of 'real' leaves...

how many of the 3 have sprouted? let's hope you end up with at least 1 female..

its not all about how many lumens or watts u have either - placing 1 125w over a plant isn't going to get any light onto the lower buds. Each bud site effectively needs its own light when using CFLs. so basically, you're better off having more individual lights and placing them all around the...

they're really not the best spectrum for flowering though - you really want about 75-80% of your lights in the 2700k spectrum for flowering. Leave a couple of 6500k in per plant when flowering - plants seem to like a mixed spectrum when flowering. 5000k is much closer to the optimal veg...

maybe i'm niave but what advantage (sounds like there isn't one) is there to smoking out of a light bulb?

what if you feel like this forever....? sorry, just kidding - you'll be fine, just drink plenty of water and get a good night's sleep and i'm sure you'll be fine tomorrow.

haha touche!

dude...this thread is about seeds - start your own thread! anyway that's nowhere near enough light.

i'd return the 3500s for 2700s and when it comes to time to flower, throw a couple of your 6400s in with the 2700s. while you're returning the 3500, go for 42/46w 2700s - you really want as much light as possible, especially during flowering. ideally you'd want 4 of the 42w (or 46) 6400s when...

BigBudBalls is right (he usually is!) - 400w HPS lights put out a reasonable amount of heat so you're going to need to be able to vent hot air with some sort of exhaust fan and supply the room with fresh air - either with an intake fan or just a passive intake (a hole). If there's no way of...

to be honest that plant looks a little small for 6 weeks.. i think you need some more light in there - get that 100w in there asap. also what spectrum lights are you using? the plant looks a tad droopy - you may be over-watering it. does that bucket have holes in the bottom to allow excess...

wow thats a lotta bud for such a small plant.

that looks flowered with CFLs, right? looks like it's got a good couple of weeks to go til those buds fill out.

is that sarcasm or were u serious? people DO grow in MG soil, but the ones with slow-release nutes in them usually end up badly burning or even killing plants. I'd steer clear of soils with nutes already in them..you really don't want your seedlings getting any nutes for at least 2 weeks...

you'd be able to grow 2 nice ones under a 150 i'd have thought - maybe 1.5-2oz each? that's a wild stab, but certainly obtainable. that's more than i can smoke in 3 months (til your next harvest) thats for sure!

Most people who veg with CFLs choose 6400k ones and for flowering, 2700k ones. IT doesn't hurt when flowering to leave a couple of 6400k in there either. Lookin good too - looks very healthy - nice colour and the LST looks good.

you'd wanna have the fan going 24/7 cos not only does it cool the grow room but as you know, with a passive intake hole, the exhaust fan will pull fresh air (along with C02) in and your plants are going to want more than a few mins a day of fresh air. if there's some way of leaving a window in...

an air purifier isn't going to replace depleted levels of C02 and Oxygen though - so you really need fresh air from another room or from outside somehow. is there in window in the basement you can crack open for a couple of hours a day or something?
