Thanks for the advice Aeroknow.. you think a 4” or 6” fan within the housing to vent the heat..? I was figuring on a filter too..

Im thinking a 12000 or 18000 BTU.. If I utilise a window unit I can do the full installation myself without bringing someone in which I’d also like to avoid if possible..

I would prefer not to have my neighbors see it if possible.. my garage is separate from my house so an a/c installed there would raise questions.. I am currently venting passively using an exhaust fan which is perfect for most of the year but I upped my lighting earlier this year, currently I...

My other option is a window unit.. cutting an aperture into my flower room, fabricating some kind of housing around the back with an in-line fan and venting the heat outdoors through ducting.. thoughts on this? Or should I just pick up a portable and use that for now..?

I’ve seen setups where guys have a window unit blowing into a tent even.. isn’t that the same dynamic really..?

Yeah I realise that but it’s a completely separate area and I’m not fussed about that area heating up.. will it still affect the efficiency of the a/c in the flower room though..?

I have my flower room inside my garage, it’s completely sealed off and partitioned. I’m looking at A/c options and I wanted opinions on whether I could mount the compressor unit which is usually outdoors inside my garage on the back of my flower room wall..? My garage is pretty large and fairly...

My main concern with the submersible is that there is always left over solution that the pump can’t pick up - with the taller res it’s going to prove difficult to gain access to properly empty it out.. I could just install a drain at the bottom initially I guess..

Yeah I might even dilute my solution a bit tonight to make sure I’m on the safe side.. thanks man

Ok I’ve just done that thanks.. I’ll see how things go over the next few days..

No my lights have been the same height for the past three weeks.. I could try raising them slightly though. Thanks for the handy info..

I’m six weeks into flower on my current run and my one strain has definitely got a calcium deficiency. I was planning on giving them nutes for a further week before starting a two week flush. The buds still look really good. Is it still advisable to add cal-mag to my nute mix this late in...

It’s a 40 gallon res but it’s due for a refill tomorrow so I’ll just wait until then.. thanks for the info - at least I know now to add the Cal-Mag first..

I've got a calcium deficiency for the first time since I started growing, just in the one strain. I’m getting some cal-mag tomorrow but I’m not sure if I can just add it to my existing mixed res..? I run DTW. Is it better to wait until I mix fresh one to add it? If so is there a specific order...

Yeah precisely.. I find that when using a submersible I end up with about 5 gallons of solution remaining in the res and it’s going to be tricky to scoop that out of a res like the one I want if not impossible.. I’m just trying to think of a way that it can pump out completely so I won’t have...

With a submersible it would have to pump up about three feet and I’m figuring I’ll lose a fair amount of pressure as a result.. maybe a stronger pump is the solution..?

I’m looking at getting a bigger res and the one I’m eyeballing is a taller narrower one than I currently have.. I could save a bit of space with this shape. The problem is that my tables will be lower than about the top half of the res and would cause my solution to drain out through the pump...

Yeah I would seriously love to do that but unfortunately a/c is just not an option for me at this point.. I know it would be the best route but my hands really are tied.. I appreciate your help man :cool:

Another thought I had was to vent the flower room straight into the veg room and then use an 8”fan to vent everything out..? Possibly then I would just need a filter on the 8” fan..? I’m not super fussed about the temps getting too high in the veg room.. Especially if I use the QB’s in that...

If the space is lessened by almost a third then surely the 6” fan will still be sufficient if my ventilation is working ok at this point in the current area..?
