My First Time Growing

Smoke, I didn't think you were rude at all! Just frustrated. You have this project on the hog train now.

The link to the pictures was not as helpful as your description. The pictures don't show what they call vent sleeves (3rd picture down) very well. It doesn't show any on the sides clearly. Are they near the top of the sides or near the bottom? A vent sleeve down low would be gold.

In the best of all possible worlds the air going both into and out of the 2x4 will pass through flexible ducting like came with your fan and filter. Do you have some of that left? Doing it that way will be much more light proof than using the velcro covered vents and would be pretty easy to do if things line up decently.

If there is no vent sleeve available near the bottom of the 4x2 the air in can come through the top of the 4x2 and the ducting can just hang down the internal corner of the tent so it lets air into the bottom of the tent without any of the velcro vent flaps being open. The velcro flaps are not very lightproof. For example, I have them on my 4x4 that sits in my home office. Even though they let a small amount of room light into the tent during lights off that light is dim and below the canopy. The light that can leak out of the 2x4 in your case might be more of a problem. Even though the velcro vents that were open would be in a tight space between the walls of the two tents there would be some concern that there would be some pretty significant light escaping.

If the flexible ducting for an air inlet doesn't line up, perhaps you could use duct tape or something similar to make a gasket between the two tents and use the velcro vents? That would also work pretty darn well.

If there are vent sleeves down low on the 2x4 and the big tent that basically line up then it would be the easiest. Just run a small piece of flexible duct between the two sleeves.

So, air into the veg tent can come in through flexible ducting from the top or bottom, or you can use duct tape or similar to make a light proof/airproof gasket between the two tents where they meet with velcro vents open on both the tents. Either way would be fine. I'd be leary of trying to use the velcro vents without a gasket. The light in the veg tent is way, way, more intense than light that leaks into the vents from a surrounding room...

Ok, that gets air into the 2x4. For airflow we also have to get air out of the 2x4. As mentioned in my last post, that may be as simple as running a 4-5' piece of flexible ducting out one of the vent sleeves in the top of the 2x4 and letting it flop over the side of the 2x4 and hang down close to the floor of the big tent. The bend in the ducting should prevent much light getting out. The dangling end of the ducting should be very close to the floor of the big tent. Negative pressure from the big exhaust fan will then pull incoming air through the 2x4 (from the bottom) and out the top. By dinking around with the vents on the big tent you should be able to get it to where when you are in inside the big tent with the doors all zipped up on both tents you can put you hand near the opening in the outgoing flexible ducting and feel a slight breeze. This will work with either the gasket or flexible ducting as an air intake strategy. Air that travels through the 4x2 will also be filtered preventing any odor issues.

There are two potential problems with the outgoing air from the 2x4:

One. There is too much light leaking out of the outgoing air duct.

Two, everything is set up but no air seems to be making it out of the duct.

If there is not enough air movement then a small fan could be used to pull air through the 2x4. It can probably be something as small as a computer fan installed in the end of the outgoing duct. A cheap inline fan is an option as well.

If the light is a problem then no worries. You simply run the outgoing ducting out one of the vent sleeves in the roof of the 8x4 and stick a fan on the roof of the 8x4 to pull the air out into the room. In that scenario the air wouldn't be scrubbed.

Remember, there is no huge hurry to get this all done. The important thing is that it all works! It's going to work. I may attempt to sketch what I've described later.

On another note, have you considered where and how you are gonna dry your harvest. It's literally a matter of days until it's time to chop, dry and trim your FIRST harvest.



There are lots of ways to go about that.
