Hi, Can anyone tell me if this is a reasonable ballast? I got it 2nd hand but the seller couldn't tell me anything about it. It came with a 600w HPS and a 400w MH globe, both work in it. I tried googling but couldn't find anything about this brand, given that it says Australian made Im guessing it should be OK but Im wondering if its safe to run the 400w MH (or any MH for that matter). Thanks

Hi guys first time grower here and have a few questions regarding the build of a grow tent. Im thinking of using a 1.2m x 1.2m x 1.8m tent but im unsure of what kind of lightning / heating / cooling setup i can use. Ive done a quick MS paint in how i think it needs to be done, Does it look correct? Do i need another fan in there gently blowing over the top of the plants as well just to imulate a breaze or something ?How bad would the smell actually get? this is just going into my shed and i was hoping to vent out of the tent and out the back of the shed, Will a carbon filter get rid of the smell? Some companies claim ZERO ODOR but im not sure if thats real? for the fans c…

Hi all, newbie here so sorry if this is a stupid question but here it is anyway....Any reason why you couldn't use solar panels to power the lighting to "save electricity, avoid detection etc..)? If anyone has, whats the setup like? I'm not planning a million dollar setup up, but roughly 2m x 2.5m x 2m......also does anyone know where I can find the hps wattage calculator needed for room size?? Cheers Paul

Hi everyone, I'm new and live in the Sydney metro area, howsit goin? I'm researching a grow room and would appreciate some advice re lighting and what people have had success with. Obviously I'm budget conscious so don't mind if I don't have the top of the line Rolls Royce model, but don't mind spending some bucks to get the lighting job done first time right time. Probably looking at your standard 2 door chipboard cupboard approx: 1800mm x 900mm x 500mm. Grow room lighting calculators suggest optimum power of 260watts, this seems a bit under done to me (calculator doesn't specify CFL or HID lighting, I suspect the former) anyway I think choice comes down to 400w …

One of my globes just blew & couldn't find any info on troubleshooting, especially visual. Came across this & seems like a good reference. http://media.hydroponics.net/productdocs/HID_Pocket_Guide.pdf Luckily, had a backup! The show goes on..

Hi, I am thinking of putting in some Uvb lighting in my garden i was wondering if anyone has had any experiance with this ? And or the scientific facts on why UVB light has such a massive part in Trichome production,size, potency,aroma etc. I will use the 23 Watt Exo Terra 200 UVB rating bulb as it seems to have the highest output of the narrow band spectrum im after. So what i would like too know is How long do i run it for in the 12/12 cycle When should i start to use it like first sign of sex, week 2 flower ? Why dont more people use it ? Does it actually make the radical difference the data suggest ( experiance from growers is what im after) And is there a LED o…

Photos here; http://imgur.com/a/X0YbQ The measurements of this closet are 145cm (H) x 100cm (W) x 45cm deep. I'm only looking at growing 1 or 2 plants, for personal use. So, my questions/concerns with this closet are mainly to do with ventilation/airflow, and light. I'm not looking at a full hydro setup as i'm trying to grow as cheap as possible. Therefore ideally i'd be looking at a 1 light setup (or similar? open to suggestion) and i'll water/feed manually as needed. How will this closet go in terms of ventilation? What, if anything, will I need, and how do I achieve it whilst still keeping the doors closed? Cutting/drilling holes in the closet are not an opti…

Will two extraction fans in series (One after the other) double the output or should the fans be parallel (Side by side) to shift double the air? Fans in question are allvent 100mm.

Just wanted to check with some people that know what they are talking about when it comes to electrics I got some cheapo grow lush 120w cfls a few years ago that came with the e39/e40 socket fixture . Stamped on the ceramic part is - MP E39/E40 500v 1500w 4kv . I am no electrician but want to know is the regulator for the cfl built into the cfl ?

Hiya OzStoners, How's tricks? I am currently looking at 150mm extraction fans primarily because I will be growing through summer again-bummer I know but hey, no meds and I'm pretty hampered in the ability to move my lower half of my body without the chronic pain of severe osteoarthritis. I can deal, but its much nicer quality of life for me, and spesh the kids when I can confuse the pain and ease my mind. Of course it is an open forum, but I consider the 150's seem to be the most widely used piece of equipment in general. But hey its just a focus, not exclusive. Parameters of airflow, silence/stealth, quality and price come to mind as a start, with and special qu…

I've started this thread to discuss the best ways to utilize a LED panel to achieve the best results possible. I hope the experienced LED growers will post their best practices to achieve the best results here in one place making it easier for others to improve their grows.One of the things that prompted me to start this post was distance of the panel from the top of the plants. It is said that in higher wattage panels it is best to keep the lights further away say 28"to 30" to increase the size and density of the buds. I kept my 90 watt Initial-LED Grow Lights at 20" and ended up with smaller fluffier buds and now after learning about the distance making a difference I w…

so after my first grow, a single plant in a pc stealth box, moved to a 1.2m2 tent & 400w hps. Crawling is fun, but i'd rather run. I picked up a Seahawk tent of the above size, along with an appropriately sized and named Phat Filter, and a centri fan that resembles a jet engine. I picked up a controller, because DAYUM I will need it. 5m of acoustic ducting thrown in, all for $730. My local hydro guy is a top bloke. I have a new property with a secure double-length brick garage (10.1 x 3.1 x 2.1). I know the owner and inspections should be irregular to non-existent after the first one in about 5 months. Plenty of time to get some beans going!! I was thinking 2x 100…

Hi, I am about to start my very first grow and am looking to buy a 400W HPS lighting kit, I've looked on eBay and this seems to be the cheapest way to buy what I want, is this safe? Any suggestions on where I should buy a 400W HPS lighting kit ?

Hey guys, Im after some advice on a lighting / vent set up for my grow room. This will be my first grow. The grow room is approx 1.2m W, 1.5m D and 2.2m H. As everyone knows, electricity is a bitch here down under so looking to minimise electricity expenses while still reaching adequate yields. I'm looking to grow about 2oz a month for personal use without spending a crazy amount on the set up. I am however willing to spend a decent amount on start up to avoid costs later and get good yields. I was thinking of doing a coco coir grow, probably 3 plants total, 600w HPS / MH for flower / veg, 6" (400+ cfm) inline fan with mountain air carbon filter. The room itself…

Hey fellow stoners, So im starting to set up my first grow and am after as much info as possible pleas from others who know how. I've decided to go with led lights and have just spent a lot on a black dog led 450w light, is quite big in size and should be more than enough for my tent which is 1x1x2, will this be enough room and enough light for three to four plants? Also what kind of grow method would be best for a beginner and easier to maintain until I get the hang of things? I was thinking of soil? Would that be best to start with? What else do I need to get before I can set up my grow? I have all the pots and stuff and a fair few seeds to, so what else? What kind …
