Have been looking at a 2.4 x 1.2 tent run with four 240w QBs or two 420w LEDs. I plan on using a standard inline axial 6" fan with ducting going into the ceiling for the exhaust system. I would like to know at what point, if ever, an intake fan is necessary or can I rely on the on passive intake? Also, I recently moved to a much more humid and damp climate, I have been battling with white mold for my outdoor plants (especially approaching harvest time sadge), feeling forced to harvest slightly prematurely to avoid looming budrot. Do you think I would I encounter the same problems with an indoor setup? I imagine that, if I control the RH of the room the tent is in, that I should be fine right, right...? Hope everyone is enjoying the long weekend, as always, I appreciate any advice or suggestions.

@PsyCLown Thank you again for the advice, I had mistakenly thought that having an 'open air' smaller grow space in a bigger room would mean that I wouldn't need an exhaust system. But if one is necessary anyway, its looking more and more like I'll have to admit my mistake of painting the room and get a tent. Anyway, feeling a lot more informed on whatever route I decide to take. Much, much appreciation!

Oh, btw I think I should make it clear that ceiling of the room is pretty high, the two sort of half walls in the corner i want o put in are just there to capture more light refraction and to have a clear grow space boundary.

@GGG& @PsyCLown Thank you for the responses, the idea for the partitioning is that the whole room is already painted in flat white paint that is quite reflective already I believe and then I just wanted the extra reflectivity of mylar for the partitioned corner (I will also put mylar all the way to the ceiling of the original walled sides of the corner) and still be able to access the plants fairly easily and have easy circulation. If it is gonna make a big difference I guess I should raise the partition higher but then, I suppose, I would need to make a little door. With regard to light pollution and air intake/circulation I am having a flat blackout blind cut for the window which will still allow circulation through the two open windows (1.3 x 0.5m each) but block out any ambient light. I will also use fans to improve circulation, more so during the flowering stage, where I stay it can get rather humid I am hoping that fans will be enough to drop the RH during flowering but I may try other things too. The partitioned corner is on the opposite side of the window. I don't know if its a good idea to line the inside of the blind with mylar as I still want air circulation? Do you think this set up will work? If not maybe I should just end up getting a tent and exhaust system. And just enjoy the blinding white of the room I painted lol. When it comes to lighting, I would prefer to get Ideal coverage and intensity for a smaller area rather than suboptimal lighting for a larger area. Also during load shedding I would want the lights to be able run off a 2kw - 2.5kw generator (I have been speaking to a friend about putting a delayed resistor on the system to handle the spike - dont ask me too much about it cause i' a total noob when in comes to electricity). So for example, if I reduced to area to 1.5x.1.5m (2,25sqm) do you think two, three or even four 240W Quantum Board LED Grow Light (Additional Diodes) from @Light It Up would be ideal, considering that I will not be supplementing any additional CO2? Again thank you so much for the responses I really appreciate the guidance.

Hello beautiful people, I am a first time time indoor grower and after hours of research am still a little overwhelmed by all the lighting options. I have a 2.8 x 3.2m room which I have painted with flat white paint and plan on partitioning a 1.5 x 2.0m corner with roughly 1 meter high plywood and coating the interior with mylar to use as the grow space. I was just in the process of ordering some lights (2 x 4bar 240w LED lights) from onlinegrowshop.co.za but decided to check some reviews before I forked out the dough, and I was lucky enough to stumble into one of the forums of this website. Turns out that onlinegrowshop.co.za doesn't seem to have the most sparkling reputation to say the least... Needless to say, I will not be getting lights through them, but I was hoping that I could get some advice from some experienced growers on which lights to use and who to source them from. I don't mind spending a fair amount on the initial outlay but obviously hope to achieve the most efficient results with regards to running costs, taking into account Eskom's proposed tariff increases, energy efficiency is paramount! Therefore, I am looking at quantum boards and LED bar lights, also I would like to use the same light(s) for veg and flowering and just lowering the lights closer to the canopy for flowering, if that isn't a huge blunder? I wont be using CO2 supplementation at this point but may look into it in the future. I have not yet partitioned the room, so if 1.5 x 2.0m is an awkward size that can be changed. I have a lot of other questions but will restrain myself to the lighting for now in hopes of getting a definitive answer. Please let me know if you have some advice. Stay safe
