  1. Hi Guys! I hope that I can get some help in my first grow. I bought my grow setup with following inside: - 1.2x1.2x2m tent - Carbon filter fan kit 4'' - 4 breathable 16L root nurse pots - 600w Lumii Black Light kit - Canna coco natural - Canna a+b I have already planted 4 seeds, 2x white widow, 1x amnesia haze, 1x Skunk XL and they are already seedlings about 3cm long. I ordered few more things which I am waiting for ph meter, digital thermometer, 2x 6'' fans for air circulation. The most important thing that I worry about is temperature, I am still waiting for thermometer to check it but while light is running is literally really hot in the grow tent so I think is too hot and 4'' fan that is connected to carbon filter is not really doing the job. Do you think that 2x 6'' normal fans will help ? At the moment my budget is really low so cannot buy some big expensive fans. In around 2 days I will try to update you guys with exact temperature. I hope you can guys help me. Looking forward to your replies !
  2. Hi all, Does anyone have any guidance on setting up extraction for rooms with co2? One of the things I'm looking at with my new 1.5x3m setup, is running un-filtered extraction through the cool hoods so I can have a lower extraction flow rate of my environment. I currently have a 5" 380m3/hr fan which has done well to keep up with the temps of my 1000w HPS. This runs through a 6" carbon filter and 6" ducting. I've built a foam and wooden box around it and surprisingly been able to reduced the noise of it from 63dB to 54dB while at 100% and from 54dB to 38dB while at 50% power. I'm looking to add another light, so I was thinking to change my cooling fan to an 8" 700 m3/hr and use the 5" for environment only. This would allow for a sealed yet small vacuum situation for co2. But if times get hot, I can have them both pulling air and can turn the co2 off.
  3. Hi All Im going to upgrade my setup after this crop (my 3rd so far only so i'm still pretty new to it all) currently have a 2.4 x 1.2 x 1.8 tent and i started out with 3 x 600w viparspectra lights. last two yields were only 15oz from 3 plants, and 18oz from the 2nd yield, 3rd one is 2 weeks to go after taking in lots of advice, it seems that those lights just dont output the kind of power needed for decent yields and for this latest crop i have borrowed 2 complete 600w HPS lights with normal parabolic reflectors, and new bulbs (omega dual spectrum, and Lumii Black ballasts). i have retained the middle LED for a side by side comparison.. so far the two plants under HPS are producing much larger and fatter colas so i'm sold on HPS and dumping the LED's. a little about my current setup: 2.4x1.2x 1.8 tent 2 x HPS Lumii ballasts and omega dual spectrum lamps 600w, 1 viparspectra reflector 600w led alien easyfeed system, 30l pots 60/40 coco 24 hour feed schedule rhino 5" 360cm3 fan, carbon filter into rhino silent theromstatic fan controller passive intake using 2 x 8" duct s bends for light baffle feeding canna nutes 1400 oil filled rad for night with inkbird controller plants are 2 x Kritical Bilbao, and 1 Incredible bulk Im growing in my cellar, which helps to regulate the ambient air, its about 15C in winter and 18-19 in summer my next upgrade will be to a 3m x 1.5m x 1.8m tent which will need extraction upgrade im thinking of an RVK L1 6" fan and mountain air or similar filter. i think that gets me up to 60 x air extract per hour even with filter and ducting my real question is how many lights for that size space? i intend to start growing 4 plants. my concern is with heat, and getting rid of it.. and the next question is cool tubes.. do i or don't I some people love them, some hate them. Im having a bit of success at the moment using a dump fan to duct cool air towards the HPS lights, but I hav'nt used this setup in summer yet thanks for takking the time to read and reply
  4. Hi, I am fighting heat at the moment and with regard to air cooled lights and was wondering if anyone has experience with this. Is there is a big benefit to cooling the lights down via a dedicated fan vs using the exhaust fan I already have? Cheers
  5. I have posted a similar question before but was hoping it may been seen by more people who can help in this catagory. Going against the correct advice given here not to buy a complete set up, I did buy a complete set up. I wish now I had listened to the advice and not bought it. The equipment is all very well made but the 250w with 250w ballast HPS light is too hot for a tiny 50x50x100cm tent where I will be growing one plant. After setting it all up and leaving a thermometer inside I left the light and outlet fan on for an hour or so and the temperature rose to 35c/95f. I think this is too hot for what I need. After reading about how to cool things down I bought a 6 inch desk fan which has done nothing to cool the tent down. The ballast is on a shelf outside and above the tent and I have a 5" extraction fan. I thought of buying a lesser wattage bulb (maybe 150w) but it will not be compatible with the 250w ballast. It is strange as it's been very cold and the room/cupboard where the tent is kept has a temperature of 15c/60f. I am at a loss especially as the people where I bought the kit from are very unhelpful. Should I sell everything and start afresh listening to the advice i've been given on this forum or does anyone know other ways to cool the tent down?
  6. Hello guys, I have a question about air-conditioning and before I start I completely understand how AC works. You have an unstable gas which draws heat from a space when it evaporates in a cooling coil then kicks out the heat when it condenses outside - typically on a roof top. My question is that with the smaller units which are fully self contained, non- commercial and have a foul air heat duct, will the air that they expel be stinking of weed and could I possibly add an inline carbon filter and supplementary fan to scrub the air?
  7. Hi. My question is that if somebody use CFL Dual Spec (6400K/2700K) than what king of seed would the best? I mean autos need 20/4 hours of lightning and with a dual spec bulb i dont have to change the Kelvin specialized bulb (6400veg/2700flow) and dont have to worry that the plant doesnt start to flowering. But somebody say that dual cfls works great with feminised seeds too, just switch time in right way. What type of seed would you recommend for a 250w Dual Spec CFl + E40 reflector? (+4x40w cheap E27 cfl from wallmart or etc.)
