I know there are numerous factors that could influence the answer...but here is the question anyway... In an ideal world, growing in large pots with soil, standard grow (not SoG), is there a general rule as to how many square feet of horizontal space a single plant needs to grow?

Thanks for clarifying PAR W. I don't think I was understanding it quite right. Nevertheless, I think my math was still correct in that I would need 12 COBs running at 49W for a total of 588W for the space. Just for learning purposes, since T5s are less efficient, would I need more total...

The setup I referenced above uses 4 COBs to produce 110 PAR W for 6 sq. ft. If I were flowering in a 4x8 space, I would need 6 of the above fixtures, for a total of 24 COBs. If I am looking for 50-70 PAR W for veg, wouldn't that mean that I would need to halve the setup above, for a total of...

4000K-5000K 3590's it is then. Still trying to figure out exactly how many I need for the space. This is copied/pasted from another thread, and probably the route I will go for flowering. @ 56.3% (4) CXB3590 3500K CD 36V @ 1.4A (49W ea) $190 (1) HLG-185H-C1400 $65 196 dissipation W -> 85.7W...

Attached is the layout of the room I have already built. I have added a possible layout for LED lights. Each fixture contains two COBs set in 6" from the end, mounted on a 36"X5.88" heat sink. Fixtures are placed 24" on center. Would a layout like this be overkill, underkill, or just right...

I have read numerous pages on DIY COB LED's. Nearly everything seems to only pertain to flowering. Would a COB setup be an ideal choice for the vegging process as well? I have a 6.5' x 8' room, of which 4' x 8' is usable for veg. Do I need to illuminate the entire room, or just the usable...

If it is questionable whether or not I will need a filter for the veg room, would it be safe bet to just install a 4" fan w filter? Another thought, could I exhaust air from the veg room into the flower room, then exhaust it through a filter to the outside from the flower room? This would also...

Just to clarify, I need a 6" scrubber for the veg room only, correct? The flower room will still need its own ventilation, correct?

When I get up and running, I will be starting with clones. For sake of argument, lets just assume I will start with 4 clones. I could get my veg room up and running fairly quickly. I could forgo leds at the moment and hang some T-5s that I have sitting in a box in my garage. Would it be best...

As stated earlier, I will not be housing mothers or producing my clones in this space. I have a friend whom will be taking care of this aspect for me. But to answer your question, there is very little to no room beneath the stairs. The stairs are only 3 treads. I know I will need scrubbers...

Yes, I want to get a healthy return ASAP. But I am also realistic and I know that there is going to be a learning curve. Ideally, I like to make the curve as painless as possible. Hence why I like to get as much right the first time around when it comes to setup. Setup is the aspect that is...

Discrete. Not super discrete though. I was hoping for $200 or less per month for electricity. Don't know if that is realistic though. I really want to build some DIY LEDs. I like to tinker. I've been reading a lot on them. In fact, that is how I found this site. Once I learn what I am doing...

I actually have access to as many clones as I need/want. I will not need to facilitate space for a mother plant either.

First post here. Great site. I just built a grow room, and I am unsure as to how best to use my space. I have never grown before, so I have no clue as to what could work. The overall room is 16'5" x 6'7" and is split into two separate rooms, one for veg and one for flower. Both rooms...
