Will it damage my plants to give them 15 minutes of dark once a week? Should I throw a load of CFLs, work lamps whatever at them to keep them in the light while the HID rests?

Cool nice and big, guessing 2.4m is the height? If you are growing sativas with 600w per plant you're gonna end up with like 18 oz a plant :D

Like the OP, I am somewhat confused by the contradictory information out there about whether or not to cut this branch or that branch. I'm guessing this is what he wanted to know, rather than the technical term for doing it. Some say don't cut any fan leaves they power the plant, others say...

Yep, little plants in big pots. If I'd known what slow growth I'd get I would have used smaller pots, but digging them out now would cause more stress than good.

I'm growing 6 plants in a 120cm square tent. I have a 250W MH bulb in a euro reflector about 15 inches above the plants, but the real distance is further than that because of the width of the grow area. Temp during the day (lights are on 24/0) is about 25C / 78F. Growth has been slow, plants...

Hi yall I have a real cheapo carbon filter. From what I understand it will work fine and get rid of all smell but only be reliable for one grow. When I set everything up in my tent, I put the carbon filter on from the get go. Then I come to realise, I really don't need it now and won't for...

Thanks yes that does make some sense. I am fairly confident that, given the way electrics were designed in houses where i live, it will be an independent breaker for the room as it is in the attic. It's hard to check at the moment because I don't wanna turn my lights out to do the test as they...

Hehe it wasn't the bulb, see my post above yours, I had set the wrong wattage on the ballast like a chump. Amazed it didn't go pop. I have a 600W hps as a backup which will be my flowering bulb but damn right actually I should get a second hps on hand in case of failure during flowering...

Thanks man that makes sense. I'll invest in a heavy duty extension *if* I need one. I'm more inclined to rewire longer heavy duty cords to reach the other outlets.

A pic would help, but dimensions would be just as good to give an idea of what you're working with. I also concur with the other advice you've been given - don't veg for a predetermined time. Veg until you have *half* filled your *maximum* grow space, then flip. Plants will double in size in...

Famous last words! I went up to set up a temporary rig of cfls on the girls while I took the bulb back to the shop to get it tested, and looked at the ballast - it was set to 400W!! Stunned - it was *definitely* not on 400W when I set it up. I must have knocked it when doing some tidying last...

Thanks man. I might take the bulb back to the shop, ask them to run it in an identical ballast and see if it flickers. Like yourself, I don't like running electrical stuff if it isn't 100%! The ballast is set to the right wattage for sure. I might just go and get a new MH bulb and be done...

Hi folks, My 250 W metal halide is flickering constantly. I have had it for about two weeks on a 24/0 schedule, and the flickering started about 1 week ago. It isn't visibly going off, just flickering in intensity. I've searched on here and elsewhere and read that it could be due to a poor...

It's rated for 250W - 600W, and comes from a hydroponics shop. I forget the brand. Yes, I plugged the light into the timer, set the timer so it would come on, plugged in the timer and the light stayed off. I guess I can't use the five gang extension cable, that's not a problem I can work...

I can understand your train of thought, but topping isn't all about increasing yield, it's about increasing the amount of light that gets to the bud sites, which helps in many ways If you grow a tree, you'll have a larger main cola, but the lower buds will not get enough light and will be tiny...

Hey again RIU! I want to ask something about electricity before I get anywhere near flowering stage and have to up the wattage. The other week I was playing about with my plug setup and timer etc. I was, at that time, running the 250 W metal halide (on a dimmable digital ballast) and the...

If growing from seed definitely. When my friend grows from clone he sees slight variation in "readiness" time due to environment differences in different parts of the room. When growing from seed though, you can have two plants of the same breed that might have totally different phenos and...

Just wanted to say a quick thanks to the OP for this thread, as I am hand watering and wondered why the bottle of canna coco a&b said to leave it out several hours before watering. I guess that is why! On the back of this I am going to mix my nutes for tomorrow *now*, not add any vinegar, and...

Hi Dakid, Let me just offer some words of reassurance from someone who *really* feels your pain. Like VX420 says, plan ahead, either get another grow on now (sounds like you will, as you have cloned). Then go buy an overpriced bag of weed of a dealer, wince as you hand over your $$$, then...

I'm no expert KoJ, but from what I've read, every couple of days should be more than frequent enough a visit for LST. Think of it this way, by topping, you are encouraging the plant to grow a bit like a candelabra or a menorah. If you top and let it grow, the candlesticks (buds) are going to...
