No - never had a hortilux lamp. Last two grow were with generic (Philips?) HPS from Lowes. Also came recommended. After ~ 1 year of use, I was ready for replacement & thought I would 'upgrade'. The Ushio was the product I chose. The extra cost (Ushio vs Lowes) seemed small when spread out...

I could not justiffy the Hortilux 'premium' I purchased a Ushio HiLUX GRO lamp. Looked like a good spectrum, was a good price, came recommended.

Depends on your grow - some guys grow in PC boxes with SOLO cups! I think 1 gallon pots are too small. I read somewhere to figure 1 gal per month of grow. You can supplement the nutrients in the soil, but you will probably get root bound. I got a small grow box & use 2-gal smart pots. In...

You should be able to get nutes online. I use FoxFarm tri-pack from an online source. I stole this from an earlier thread for future reference ""General Organics is easy and forgiving. Get the Go Box.. Nute schedule on their site. start with 1/2" I have no idea what soil is at Lowes. Why...

What nutrients are you using? As others have said, the manufacturer will recommend a feed schedule. Fox Farms offers a feed schedule for use with their nutes: http://foxfarmfertilizer.com/index.php/frontpage/feeding-schedules.html http://foxfarmfertilizer.com/images/pdf/SoilENG.pdf

Day 10 of flowering, or 10 days after you flip the lights to 12/12 ? It looks like most the plants have not really reached the screen. Maybe you could lower the screen? I would keep training for ~2 weeks after your flip the lights. If you think you have a strain with more stretch, maybe you...

A quality grow is more than the sum of the parts. It includes how the parts fit together+ your skill set. I can't comment on whether the parts are complementary (e..g, is the exhaust fan the right size for the tent & filter? Does the light fit the tent size?) This list looks good (except for...

Harvesting early is a common error. You can gain a lot of weight in the final two weeks.

Great thread & photos! I am trying this method with my new grow box! From page one: So you only top once, or do you go ahead & pull the (4) new sprouts? I know it is an option, just curious what you meant in the quote above. For this grow, I think I am going leave it as is with the one top...

Sorry to hear - Good luck on your next grow !

I am not sure you can cut holes in the closet door or the ceiling if you rent. If it is a common door, you could cut holes & replace the door when you leave, but still...... For me, I don't mind the fan noise. Sounds like 'white noise' and can drowned out other noises (e.g., traffic, etc.) You...

Nope, never did this. You got the right idea - match the ballast setting to the bulb. You probably just took some life out of your bulb, prematurely aging the filament. You may know some (lumatek) ballast have a boost setting, to allow you to get more out of bulb than the manufacturer's...

Sorry - I got no idea. This has never happened to me. Any additional info? bulb brand new? used ballast? Has this ever happened to you before? If you have a multimeter, you could check the output of the ballast. I am unclear whether you can check the strike. Assuming you can not service...

Your venting may depend on your required 'stealth' needs. If you don't have to grow in secret, I would have a passive air intake at the bottom of the door, and a fan exhaust at the top of the door. I would include a carbon filter for odor control. I am not a big fan of venting to the attic...

Nice grow - well done! I have a new grow box very similar to yours. I hope to get as good as results! I am using smart pot and doing some LST with stakes in the soil (4-way LST method). Someone else mention using clips on the side lip of the pot. What strain did you grow? 30 days from clone...

I use T5 for vegging and they work fine for me. I have a small grow box, and do not veg very long, so the high-output T5 does the job. But there is something about 'canopy penetration' where HID excels. I am unclear on the scientific reason why. All things being equal (e.g., lumens), HID is...

I got a whisperline in my bathroom! It is quiet, but you still hear the air flowing throught the grill. You may want to consider a grow box instead of a tent. The extra mass of the walls will help quiet any growing noise. I bought a Can fan & filter. Both high quality. You can find them on...

Assuming you get a quality fan, I think most of your noise comes from the air movement, not the fan motor. The 6" may be quieter than a 4" fan, but I don't think this will be significant. A 6" fan would probably be overkill for your tent. A 4" can fan (or vortex) should be fine. Get a quality...

fans all the time. I run an exhaust fan through my a/c reflector, and a circulation fan.

No one mentioned ushio's enhanced spectrum bulbs? Lower cost than Hortilux, and a broad enough spectrum where I feel OK to veg with. I have a small segragated grow box, so I don't veg too long. I germinate/veg with CFLs and T5, then veg (as needed) and flower with an HID w/Ushio. I don't use...
