 original post from RIE (a harvest every two weeks)
 A harvest every two weeks with Sea of Green This style of op is known as 'Sea of Green' or SoG. You can build this op in any scale you like, from a single mother and just one plant put in to the flowering area every two weeks up to as big as your needs require. The idea is to grow only the top cola of a naturally growing plant with none of the lower branches and the small buds those branches produce. All branching, pretty much everything on the lower 1/3 of the plant, is snipped off in about wk 2 & 3. The method of putting clones in to flower with no vegging time keeps plants relatively short, to about 36-40" (1 metre), which better suits artificial lighting. Even powerful HPS lighting can only penetrate foliage so deeply, so a metre tall is just about right. I find that big lights give better bud density, so I use two 1000W HPS, one over each pair of 4' x 4' flood trays. The mums are maintained under 24 hour 400W HPS. The clonebox has 6x 18W fluoro tubes (24"), usually on 24/7 but shut off for the first 6-8 hours after doing a new batch of cuttings. Clones go straight from the clonebox into the flowering trays- no vegging required. They grow a little bit vegetatively for the first 3-4 weeks but then stop getting taller and start making bud weight after then. I keep about 6-8 mothers and do about 30 cuttings every 2 weeks from them. I choose the best 20-23 clones to be put in the 4-tray flowering area. Leftover clones become replacement mothers or are discarded. Mothers are replaced one by one, about every 4-8 weeks as needed. As each batch of clones goes in to tray #1, a batch comes out of tray #4 to be harvested, every 2 weeks. The mother vegging area is in the same room with the flowering plants, but has a lightproof curtain to prevent interrupting the flowering plants' lightcycle and has its own ventilation system as well. Each tray in both the veg & flower areas has its own pump, reservoir tank and timer, allowing the watering rate and nute mix to be tailored to the plant for vegging as well as during each 2 week phase of flowering. The op makes 13-16oz every 2 weeks, sometimes more if all is going well. I guess that's 360-450g+ every 2 wks Figure that the entire grow op fits in a cramped and tiny 7' tall x 8' wide x 9' long space. High weed density growing. What kind of plants are you growing? - Sweet Tooth #4 from Spice of Life Seeds I think you have six mothers? Well when you take 30 clones from them how long does it take for more to grow back. I know it has to be least then two weeks.- Takes almost exactly 15 days for the mums to regrow. They'll have new material about 20" tall in that time. I raise MUCH more mum material than I need. I compost about 2/3 of the new material from each mum each time I do a pass of cuttings. However, overgrowing the mums this way, I am assured of healthy, thick stems for top performing clones. The fatter the better. What kind of hydro setup are you using?- It is a flood hydro system, even for the mums. 5 trays total, 5 tanks. Cuttings are rooted in rockwool cubes. I use 8" plastic pots stuffed with loose rockwool for raising plants. No soil- no thanks. I thought this might be helpful |
