Bucket grow / Led Strips DIY (85w SMD5730)

Dear all,

I'm creating this thread to share with you how I managed to grow my weed on low budget, on a funny and practical way.

I wanted to have a small grow set up, with minimal equipment and logistics. Basically I wanted to have my grow space fitting in the living room and barely noticing it is there. At the same time I didn't want to spend too much on equipment and keep my electrical bills low. Plus, going to a shop and buy a ready-to-use system is not my thing, I prefer Mac-Gyver-it. I'm proud too grow weed without ever entering on a grow shop :)
The system is light and mobile, in case I need to move it, just need to unplug from the wall and take it to another place, every components are inside or attached to the bucket,

I got a 23L plastic bucket, added 10 meters of LED light strips SMD 5730 and installed two fans on the lid, everything for 40$.
The LED strips I got from ebay, 6$ which roll of 5meters. I got rolls of red, blue, 2700k and 6500k white for this and other projects. After playing with the LED strips for awhile, it seems the 2700K and 6500K do a better job than the others, unfortunately I didn't know this when I ordered the LEDs, so I ended with more blue and red than I wanted to.
I added two small fans on the top of the lid for air circulation and cooling the leds, the average temperature inside the bucket is 24º, with peak temperature of 27º (very rarely).

On my set up I cut various LED strips in small 30cm parts to fit in the bucket, wired them in parallel and connected to a laptop like AC-DC power supply, rated for a max of 120W. It took about 2 hours of soldering as I'm inexperienced with the soldering iron.
My watt meter tells me the lightning system is pulling 85W from the wall.

I'm growing an auto strain on a 2L pot. The results are not fantastic but I wondered if with 85w CFLs or T5 I could get more weed on an equally neat set up.

Some pictures:

Day 6 (day 1 - soaking on a glass of water)

50w of Blue and red around the bucket, 35w of 2700k and 6500K on the top. Seeds are unsexed, let them grow and cut the males if any balls show up.

Day 21
One of them had balls, gone!
If I had started this grow with a single female I believe the vegetative stage would have been much more vigorous. With 3 plants on a 2L pot and 85w the growth was far from optimal.

Day 29
Another plant showed balls, gone as well.
Once this plant was let alone in the bucket the growth was much faster, unfortunately it was a bit late as she was already flowering for a week.

Day 32
Small and bushy. She's far from the center of the pot, not good for proper root development.
Dark green leafs indicates she's getting too much nitrogen, started feeding more gently.

Day 38
More bud development. Used some fishing line to lean her to the center of the bucket to unsure better light distribution.

Day 42
This is how she is looking right now. Things getting more frosty and smelly.
Noticed a bit of nutrient burn, not a problem but something to keep in mind next time I feed her.
PS: I'm feeding her with orchids nutes ahah, seems to work :D

In the end the yield will be ridiculous when comparing to many grow journals in this forum, still the fun of projecting and trying something different is more appealing to me than the quantity of weed I get.
This girl have another 2 weeks to mature, after that, I would like to grow a photo strains and LST her to take advantage of the lighting positioning on the bucket.
Later, I will open another topic to give more details about the bucket / lightning set up and show some work in progress. Is not that I'm amazing with this DIY things, just would like to share how I did and why I did the way I did to those interested in LED strips and small grows set ups with minimal costs.

Feel free to comment. Suggestions, questions, critics are welcome.

More updates will come :)

Awesome grow metacanna. This is something I've been wanting to do for awhile now I found some strips that put out 1870lm a foot at 15.4 Watts they cost 140$ for a 3m roll though. Kind of expensive but so is buying our beloved plant

PS I can't believe your doing this in a 6 gallon bucket amazing

Really interesting project. I can't help thinking the lights at the bottom are being wasted though - the soil level is so far above them.

Yeah, the bucket is small, but with 85W and auto strains there's no need for something bigger. It is 1 foot tall.
Concerning the super efficient strips you would like to buy, I would keep it simple and cheap instead. If I was willing to spend more I would buy COBs instead.

plimsoul, you are right, in my next grow that's going to be fixed. I got a a new pot that fits perfectly in the bucket in a way that no light will be wasted, with a larger diameter and less depth.

For comparison, I think CLF or T5 would be unpractical in this kind of set up due the space necessary, plus the heat would cook the plants and in the end I doubt it would yield more. Ah... and the cost...

It's like putting the plant inside your reflector. I like! Total penetration is all but guaranteed with just a touch of training.

It would be easy to create a lift and pulley system that the gardener could step on to lift the plant up to, say, even with the top. This would eliminate bending, stooping and reaching into the bucket to work the plants. @Metacanna, would such a feature be helpful?

The more I think about this concept, the more I think it would scale up pretty well. One would certainly want to implement a good training and pruning regimen, but what if the 'bucket' were 6'/2m in diameter, similar height, with a couple thousand watts of very softly driven COBs, thereby maximizing efficiency while never sacrificing intensity...?

Things that make ya go hmmmmm....

In this situation I had to bend the plant because she is not centered in the pot, if she was on the center I wouldn't need to bend her. There's no risk of touching the top lights, I think by bending her the light is better distributed.
In fact, during the growth I have been using some objects under the pot to lift it so the top canopy is always at least 5cm distance from the top lights. Somehow this is a simplification of a more complex lift system as you suggested.
As the plant started gaining in height I lowered the pot by using smaller objects under the bucket, always keeping a distance of around 5cm from the top. By "object" I mean anything I have around that can be discarded.

If I wanted to scale the concept that's what i would do, COBs! LED strips are only useful if you keep them within a small distance from the plant, the power output decreases fast as you increase the distance. I would use one or two powerful COBs on the top, with the heat sink installed outside of the bucket to prevent overheating and then some side lightning with LED strips. I imagine what could be achieved with 100W LED strips side lightining plus 100W COBs on the top on a slightly larger bucket.

Day 58

Just harvested my plant, it has about trichomes 20% clear, 70% milky, 10% ambar.

Yielded 52grams wet. For this small plant I think it is acceptable. Next grow I hope to beat that number.

Fuck yeah mate, that's a pretty solid effort, I like the concept. It would be pretty simple to set up 4 or 5 of these and get 200-250g, that's pretty neat :)

There was space inside the bucket for more growth, instead of more buckets it still possible to install more light inside the bucket. It would be easy to upgrade to 150W and keep the same temperatures. Also, I could use a bigger pot (more diameter less depth).

One of the biggest reasons I like this concept is because it's so saleable... Imagine the plant you could grow in a refrigerator sized chamber!
