Usually negative pressure works best, from an exhaust moving more air than the intake. How big is the tent? 2 x 1000 seems like a lot of watts...
Don't beg for the ladies. Veg for them, but don't beg for them. :) I've seen good clone and mom setups with t5s, and they don't make much heat....
It's hard to answer that. It definitely hurts the airflow reducing. I wouldn't even try it on anything over 400w, but I have seen it work, when...
Looks good. She's going to love the 250.
Best I think is to get the tank at somewhere the refills them. Lot of places just exchange empties for gas-filled. You come in a with a shiny new...
I was wondering how many floors down 55 gallons of rez could leak...
I think the silencer may be unnecessary, because I think the inline is unnecessary. I cab that size running LED could easily be cooled with a...
How many days do you expect temps to be above 90? If it's more than a handful, then our friend from Quebec really is giving good advice. I'd say...
There still are risks in even in the scenario above. I would be thinking of a stealth grow in a cabinet/armoire/etc. Two advantages. One, is...
1. In flower, probably. In veg, yes. 2. From an air source cooler than ambient. Outside, if temps and conditions permit. 3. What size is your...
Don't let that beast reproduce!
It's not optimal, but it can be done. I would make some kind of ducting on the exhaust side to carry air away from the intake, if that makes...
More light would also be significantly cheaper than co2, even if it required upgrading ventilation.
Keep a 5w bulb on at all times, to make sure darkness doesn't exceed 90%
Are you going to build your own window kit for it? The reviews seem to indicate that's where it falls down.
Wow, I didn't imagine a situation quite like that. Kudos to you, PE, for having a straight-up relationship with leo.
Yes, you want more pressure on the exhaust side. That creates a pull on the intakes and keeps air and scent from seeping. If you're talking a...
Beware of $26 dollar LEDs. Might be better to just get CFL if your budget is tight.
Get a 250w HPS. Electricity costs by the kilowatt hour. There's no advantage of having a 400w floro vs. a 400w HPS.
85 is getting up there, for a flowering plant. Play with the exhaust fan. That will have the most effect on cooling. The dry ice idea sounds good...
