Cannabis Grow Rooms

Hey Peeps, I'm contemplating introducing co2 in to my GR and before i fork out $$$ i decided to have a look around this fantastic site for more info. Unfortunately navigating this site is not my forte` especially since recent changes - my searches tend to result in 100's of unrelated posts so i'm hoping you guys/gals can help. Does anyone know if theres a 'pinned'/tutorial on co2 enrichment and if so can you point me toward it? Also, anybody that has experience with c02 enrichment and has any handy tips would be greatly appreciated. I know the theory i.e. required concentraion of co2 [ppm], balancing exhaust with co2 and rough costs involved but i'd really like …

I decided the scrog wasn't recieving enough light, but there wasn't room to hang another reflector. The solution was to cut most of one half of one reflector off and to join it to the other reflector. This will allow me to hang two bulbs above the scrog without needing the space for two reflectors. Due to the lamp holders being slightly different one globe hangs a little lower than the other, but that shouldn't be much of a worry. I can't wait to double the wattage in there, and when it's time for lights on I will hang the new double reflector and show you all how it looks. Naycha

Yo guys. I've been trawling round here, reading up and studying what I'll need to know to embark on my endeavor. If anyone has any advice or can see something I haven't covered please let me know. So anyway here is the plan as it stands. I haven't started purchasing things yet, but that will be very soon, hence this thread haha. So i'm gonna kick it off in my wardrobe, which is about 5'9" tall, about 80cm wide and around 45cm deep. The room gets solid airflow from a large window, and I don't expect to need much more than a standard fan for summer. I don't intend on more than one plant to start too btw. As such I doubt scent will be a predominant issue. As far as …

I have just put my babies in there new home and have the temp just right (26c under the lights) I have an air con (portable) running during the day and also have a fan in and out for airflow. Do I need to put in a fan to move the air around despite the fact that I do not have any hot spots in the room (air con works a charm)? I have been told by some that a padistal fan is needed to strengthen the plants with a gentle breeze, while others seem to talk about using the fan soley as a technique for moving hot air from under the lights. Any thoughts would be apreceated.

i am looking into a wardrobe/cabinet diy setup and in my research so far ive come across LED, but there isnt a lot of info other than its new and they may work. while on ebay i found a 225 led blue nd red system and cheap only 45 bucks with free delivery but there only 30.5x30.5 and thats small for my setup, i was thinking if these are a real product i would have 3 or 4 on top nd at least some on the walls because from the pictures it looks like the plants are not getting light over the tops and what i was also thinking i rotate the led on the walls to try to give an even grow. if these are not worth it, i would be fitting a 400 hps and try some computer fans but reckon t…

Hey guys, I want to set up a small grow room in my cupboard (125cm H, 55cm W, 60cm D)for 2 - 4 plants. I want to spend the least amount of money possible (preferably under $150) so I was thinking of using CFL's and just having a small turny fan for ventilation with holes in the back of the cupboard. What's the go with using CFL's for a small number of plants in that kind of space? Cheers, Nax
