What started as a swell idea last week is now being put into practice.... Since I moved away from the Netherlands, I've been annoyed that I have difficulty getting any decent quality grass, or anything at all, especially if I want to avoid the criminal crowd. Now a friend of mine wants to try MaryJane for her Morbus Crohn, a chronic bowel disease, and I figured "How difficult can it be to grow stuff myself?" Okay, after a week on this and other forums, I realized it ain't that easy or cheap. My current $400 plans look as follows: System: - Cabinet ~ 3' width, 2' depth, 6' high - Carbon filter with UFO vent in the ceiling - 2 holes with thingies to keep light out at bottom - Doors light-proofed with soft plastic stuff (no clue what that is called in EN) - 400W Natriumdampflampe (halide), 8 kilo's in weight (professional quality) Grow: - ScrOG method on soil, probably for orchids or something - 2 long plastic containers with frame for netting, each with 2-3 plants - Female seeds, probably Northersn Lights x Big Buds or similar - 4-8 weeks on 24/0, then slowly down until 12/12 for flowering, no pruning My goal is excellent quality, good-okay quantity and possibly not too long until harvest. The box will be built in the 2nd week of August, the seeds I want to get Monday already, germinate them in water and put them in Jiffies in a small plastic greenhouse on my windowsill. The growbox will be placed in my bedroom. Do I need additional CO2? Do I need to be able to manipulate the light's height, how far does it need to be from the screen? How often do I need to water, how often to fertilize? What kind of timing can I expect - how long before I need to train them on the screen, how long before they fill the screen, how long for them to flower on 12/12? Any suggestions are greatly appreciated!
