A Space Bucket is a DIY indoor garden that is made by stacking plastic containers alongside lighting (CFL or LED) and airflow (PC or other fans). It is an enclosed growth chamber that can be used to garden many kinds of plants. A Space Bucket is a versatile gardening tool that can be adapted to the users needs. Every variable of the bucket environment can be tweaked and upgraded at any time. For example, some plants require more light intensity than others, or different humidity conditions.
Space Buckets is also a movement of gardeners, a community of botanically inclined individuals who like to grow plants indoors and share information freely. The /r/SpaceBuckets subreddit is our main forum, and this website is its companion. Bucketeers are open, friendly and thorough, as the manifesto states.
A Space Bucket can be used very effectively for cannabis cultivation, but that is not its only function. All plants enjoy the bucket garden, especially herbs (basil, chives, thyme, rosemary, mint and more) and fruits like cherry tomatoes and hot peppers. Bucket plant experimentation is encouraged! Why not some SB avocados, succulents or potatoes?
What plants can I grow with this setup?You can grow any plant you can imagine! Space Buckets can be used for the entire life of most plants, and also works great for germinating seeds or maintaining clones. You will see that Cannabis is a very popular choice among bucketeers, but its not the only thing that thrives in a Space Bucket. Users from the subreddit community have grown Tomatoes, Peppers, Dill, Chives, Basil, and even Wasabi and Avocado! You are invited to try new types of plants, every species deserves a bucket.
What type of lighting should I use?You can choose CFL or LED for your bucket. In both cases a minimum of 100w true watts is recommended. The LED option can be solved with a UFO light. The recommended size is the '180w' model for a typical Space Bucket. If you go the CFL route, about 4 bulbs will be needed. You can mix spectrums (2700K and 6500K) during the whole life of the plant, though warm-white is preferred in flowering. Either configuration can be used along 5050SMD LED light strips. These lights stick to the walls of the bucket for extra photosynthesis and higher yields.
A note on color temperature: Higher Color Temperature (CCT) is used for veg growth (4000k+), as bluer light helps inhibit stem elongation. Lower CCT is used for flowering (2700-4000k) as red/yellow light is associated with flowering growth. Lower CCT can be used for veg if compensated by higher light intensity (to inhibit stem elongation.)
Target Lighting LevelsThere are several different 'ideal' levels of light intensity, depending on the stage of growth your plant is in. The following information is useful when figuring out how much 'headroom' you need, or distance between your light source and the canopy of your plant (many people use 'bucket spacers' to gain distance) (NOTE:: Lux meters in general should only be used for white light. (not mixed/monochromatic light sources e.g. 660nm red LED, 440 blue LED etc).
Using a lux meter, measured from the top of the canopy.
5,000-7,000 Lux - Seedling
15,000-20,000 Lux - Vegetative Growth
35,000-45,000 Lux - Flower
75,000 Lux- Point of saturation and pointless to exceed.
