6 T5 tubes over 4 or 5' seems lean. If you train, and don't get too big, could be OK. My T5 fixture has 4x2' tubes in ~14". Maybe ~3" separation between tubes. You are going to have 2 together, then 10" gap? then another fixture, etc. You have already bought the T5? If not, your operation...

Sure, it would work. 2 rows of 4 plants under 4' lamps. I am currently vegging 2 plants under 2' T5. Works well. How long do you plan to veg? You may have some space & canopy penetration issues with your setup if veg for a long time with no training for plants. I got a small grow box, and I...

I bought: lumatek ballast ushio lamp Can fans & filter Hydrofarm XT6AC reflector (good value, better ones out there) Take a look at ebay, craigslist, amazon, etc.

If you got the room and the $$$ and can keep the temps down, go big! For 8 plants, I would also consider a 600W min. I don't like the 150 size. For HID, I think 400W is the min (good for a ~2.5x2.5' space). For bigger spaces, get a bigger lamp. I have a 4x2' T5 for vegging, then a separate...

Looks good! These are two new strains for me. I could not find any info on the net. Looks like they have some sativa in them. Local strain from local grower?

Let's not say stupid, but maybe 'killing with kindness'?!? The seedlings do look like they are having a hard time. Be patient, maybe less water, and easy on the plant food. I have not grow in coco, but your seedlings should not need food right away. The first set of leaves should not turn yellow.

You might want to consider some 'beer can' reflectors for those CFLs. There are a couple of DIY thread out there for this simple project. I added these to my last CFL germination & very please with the results. I have a fan blowing on my plants & the CFL ~1.5" away from tops. Worked great!

You may struggle to light all your space. It is tough to provide illumination to a rectangular space with one light source. I think I saw a reference document that said a 400W lamp was ideal for 2x2 space (may have been 2.5x2.5). Ever thought of dividing your space in half? veg one side, flower...

I like the 250 better than the 150. If you get a fan to cool the lamp, I still like a 400W. It is a better fit for a 3x3 space, and may work better for your next grow area! You could still have a good grow with the 250. I got a Can fan RS4 off ebay for $90. I wanted a quality, quiet fan for...

Depends! I leave my circulation fan on 24/7 If you use a fan to cool your lamp, you could turn that off when you lamp goes off. Just monitor you temps & humidity to make sure it stays in a good range. Some people modulate the fan speed based on the room temperature. I also leave my lamp fan on...

Are you going to have an air cooled reflector? w/exhaust (not just circulation)? A 3x3' footprint can support a 400+ W lamp.

$40 is pretty cheap for this type of fan. Never seen a centrifugal this low. Could be a good deal. ~210cfm I have never hear of the brand. Might be a bit loud but should work. What are you doing with the fan? Just circulation/exhaust? Or are you cooling a lamp? pulling through a filter?

Helllooooo oliverdolls! First post w/a lot of questions! i had to get the calculator out! If you can afford 4x1000W lamps & keep them cool, great! Do you have a separate area for vegging your plants? germination? You may want to divide your room to have separate areas. Posting this in the...

HA! learning2farm is learning2post! You just answered a 2+ year old question! Still, good advice..........and I have answered old questions before too....

I like the google list ! Here are a couple of thoughts: I don't see anything about odor control. Even in a legal state, odor control can be important to reduce nuisance and improve security. The fan cfm (and cost) may be a bit small, especially if you are going to add a filter. What about...

ice bong. Kind of a hassle to get it set up & then clean it afterwards for only a couple of hits on a weekday evening. But it is nice.....

Nice - plants look good & healthy! You got a couple strains that are new to me. Next time, where possible, let us know what photos are what plants. Might have to try one of these .....

I don't think a wall A/C unit bring fresh air in. Most just recirculate & cool the air. The back of the unit is outside & used to vent heat and condensate. You may need a way to bring air in, and exhaust air out.

Sounds good. Indoor grows usually include odor control. Not sure if this is a concern for you, but this is one of the things to consider when you move inside.

High flow also add to your noise and may use your filter up prematurely. If you can manage the heat, turn the fan down!
