The only nutes and soil I can find locally.

Note: It is important to avoid any Miracle Grow soil with “time released” nutrients for growing cannabis. It will seriously hurt your yields.

Final Yield: 29g = 1.02 ounces

Total Cost:

$200 including price of seeds

The only things I bought for my CFL microgrow are displayed in the picture above (except for the 125w CFL which cost

The seeds cost about $70 for 5 x “G13 labs OG13” feminized seeds w/ stealth (insured) shipping

Growing Medium – Soil & Perlite

Miracle-Gro isn’t the best soil for cannabis, but it was all I could afford/find. You gotta work with what you can get. There’s no such thing as a grow shop in my city.

Just make sure you do not get the Miracle-Grow soil with “time released” nutrients! That means do not get the “orginal” Miracle-Gro potting mix. It will burn your plants in the flowering/budding stage by releasing the wrong type of nutrients at the wrong time. If at all possible, I highly recommend you get better soil for growing cannabis to start!

I used the Seed Starting mix for the seeds, and a mix of Organic Choice and Perlite after that

  • Total of 218w of CFLs

The room she’s growing in is in a room pretty far from the entrance to my apartment, inside a cabinet you could pick up from IKEA.

The grow space is about 1.5′ x 1.5′. It’s only one plant so actual grow space is probably closer to 1’x1′, since I have the bulbs about 3″ away at most. I give the plant a 90 degree turn every couple days.

There’s a bar about 4′-5′ up that the zip ties are connected to and I wrap the cabling for the lights around it to secure them.

For the most part I just hang them but the bulbs on the left I jerry-rigged; it wasn’t close enough to the buds so I made hooks on the ends of a straightened piece of clothes hangar.

One end went around the Y-splitter the other the edge of the wing and it brings the lights in sufficiently. The reflectors are made from folded over heavy duty foil–heavy duty is the only kind that retains its shape when molded.

How much did it smell?

I think I’ve gotten used to the smell. I don’t even smell it anymore, lol. When I walk into the room I only smell slight hints of it. Even when I put my nose against it it just smells like slightly herby grass.

But if i just brush the plant with my fingers and bring it to my nose it smells like a real earthy varnish, STRONG.

My friend who doesn’t smoke says he smells it when he walks into my place but only because I told him about it, if I didn’t mention it he probably wouldn’t have noticed it.

No smells in my hallway at all. (I live in an upper floor apartment landlord is never around.) I’ve also had other friends/family around but no one’s ever said anything so I think he’s right.

When the lights are on I leave the cabinet open. It’s in a room that gets real good air circulation, when I leave the window open a crack I get a nice gentle breeze and the temp around the plant is spot on 77f with a RH of 20%. So I kind of lucked out on not needing a fan/carbon filter to control odors.

Vegetative Stage

  • Vegged for 30 days using just the 1 x 125w CFL 6500k bulb located above the plant
  • FIMed once on week 3 (the third grow node was just coming in)
  • Transplanted a couple days before going 12/12
  • I didn’t defoliate during veg at all, as I didn’t read about it till about a week into flower. I hear you see best results when you start defoliating in veg so I’ll definitely be trying that for my next grow. But even for starting defoliation 2 weeks into flower I’m pretty happy with the results.

The 125w alone was more than enough for veg. In fact, I think I could’ve fit another plant in there if I used a smaller pot.

Here’s the plant in the seed starter mix + perlite.

At this point I moved the plant to a 5 gallon pot filled with only about 3 gallons of soil. This time I used the organic mix + perlite.

Flowering Stage

  • I added the supplemental lights (4 x 23w CFLs) on the side after I flipped the lighting to flower.
  • I started LSTing a week into going 12/12.
  • Started defoliating 2 weeks into flower, gradually. (10%-20% of the leaves at a time every 4-5 days)
  • I ended up clipping all fan leaves about a month after the start of flowering and just adjusted LST so the canopy remained open.

Day 10 of Flowering (40 days from seed)

To tie the plants down, I cannibalized metal clothes hangars. I stretched and straightened them with pliers and then clipped them to whatever length I needed bent in half so I could stake tops down.

Day 60 of Flowering Stage – 3 or 4 Weeks Left Until Harvest
