Score some pictures if you can. I'd like to see the setup you're working with.

Well, you can just water your soil and place a dome over the cup and that will trap moisture or you can mist your plant a couple times a day. Misting is usually done with clones because they have no roots whatsoever and you should be careful if you're misting under an HID because the water...

I would say yes. I neglected to put a dome over my seedlings last month and it seems they suffered due to the low humidity around the leaves. A few appear stunted and others exhibited considerable leaf shredding. A further point, I believe that seedlings with an undeveloped root system chiefly...

Too much, but you live and learn right? I spent about the same as I would on an ounce of weed. It came out to a little over $300, but a decent portion of that was for tools that I didn't have and decided it was finally time to buy. I spent about $105 on 14 lights at 1000bulbs.com Around $50 for...

I got the idea from this thread. I followed essentially the same pattern, just smaller.

That looks nice! I'm interested in how much she yields as well. I'm not sure about the size of your room, but if you're working inside a cabinet or a grow box, I built a small carbon filter exhaust fan that works pretty well. It's a pretty simple variation of some DIY scrubbers posted...

I've read and agree that though during the flower period the plant needs the spectrum of light generated by the 2700k bulbs, the plant is still adding mass and has a use for the 6500k wavelengths as it did during the vegetative phase. I would work it so that during each phase, you have a...

Shouldn't you have 2700k (red-ish light) in your flower box and 6500k (blue-ish light) in your veg box? It looks like you may have it backwards

I'm using ten 42 watt cfl bulbs in my growbox. I've got a mix of 2700k and 6500k with the balance tipped towards the 6500k for veg. When it's time to flower, I'll be switching a few of the 6500k for 2700k bulbs in order to tip the balance the other way. Check out the link in my signature

Close ups of the plants. One looks like it has some female preflowers emerging, but the camera on my phone couldn't capture that level of detail.

That's looking good man! How big are you going to let that thing get? And I hope it has survived all these thunderstorms we've been having!

Here we are at the beginning of the 5th week. The plants have been responding well to LST, supercropping, and topping. As a result of the LST and supercropping, the lower branches have reached upward to become tops themselves. Being my first grow I hope I'm not being too rough with the...

Plants at 2 weeks following a recent a transplant from the soda bottles. I began LST and other grow technique experiments shortly after this point. In some of the pots I have left the soil down low so I can bury the stem of the plant and test that technique of increasing the plants number of...

To finish off the box, I installed the fan in the top right corner and sealed it with finger caulk weather strip I found at home depot. I cut intake holes in the bottom and picked up two, 4" desk fans from Target to act as circulation fans. I ordered a pack of 10 Blue Mystic seeds from...

I still needed a fan, so I used a 4" inductor booster fan rated for 80 cfm. I don't think this fan would hold up very well in a larger space, however it keeps air flowing quite well inside the box and keeps the temperature right in the sweet spot , 75-79 degrees. I put a flange on the end and...

Next it was time to make a trip to Home Depot to collect supplies. I used 2x2 treated pine to build the frame and finished it with painted MDF. I attached casters to the bottom in order to make the box mobile. MDF is pretty heavy stuff. I then built a light fixture. It holds 10 CFLs up to 42...

After having spent quite some time lurking around rollitup, doing my homework, it is finally time to begin my first grow journal! All of the posts here at rollitup have really helped me get this project successfully off the ground so before we get to pictures, I would like to say thank you...
