Many growers think that to be a successful indoor grower you have to go hydro. I would like to present an argument for my organic system.
First of all you should refer to Bushy's Indoor organic tips for beginners in the basic grow room.
All knowledge is practical and has worked well. It is a very simple organic system that is much easier to master quickly than Hydro systems. No meters required, hand watering allowed. This system is cheap and easy to set up but it requires some space, some electricity, and some work.
First the grow room should have at least a 400 watt metal halide light and a few fluorescents for clones and/or seedlings. A 1000 watt MH is preferred depending on the size of your flowering room.
400 watt in the grow room is minimal for a 2500 watt flowering room to stay maximized. Under the 2 or 3 (4 ft. fluorescents start your seeds/clones) keep the growing tips about 1-3 inches max from the light tubes if they are regular 40 watt flor tubes.
I start mine in about 1 Qt pots as seedlings or clones ( I do both) I usually start about 10 every 2 weeks. The perpetual harvest is never all at once, it is more of a production line system, with continual harvesting. As the seedlings reach about 8 inches they are moved into the bigger grow area with the 400 watt metal halide light. Soon they are big enough to transplant into 3-5 gallon pots, depending on size plants desired.
After transplant into big pots the plants need to veg for about another 1-2 weeks until fully or mostly rooted. Rushing this process will hurt eventual yields. I like bigger plants, this is nothing like SOG. If you want to make hundreds of clones and go hydro then SOG is a high yielding system but I like killer larger buds.
The plants spend about 5 weeks in vegetative stage. When moved to the flowering room they are rooted into large pots and usually about 2 feet tall (this varies with your set up, head room, genetics, etc.)
If you have used good soil mix (refer to Basic Tips) and the plant is healthy it should be shooting in fast growth as it goes into flowering. Amazing beautiful bud growth will be seen if all is well. Healthy plants will stay dark green until late in flowering, keep feeding them organic ferts with some Nitrogen in them like Pure Blend or add grow fert to the no Nitro fert if the plant gets yellow.
Make sure you add some co2 to the air twice a day at least in flowering. I water every other day usually and I feed them every other feeding generally. Keep them happy and large yields can be obtained in a 3 month total grow and veg time. 3 oz per plant is not uncommon. Under a 2600 watt flowering room about 24 plants of this size can be grown. This means 4 plants per week to harvest. Ideally it is possible under about a 4k system to grow 10 oz of organic dried bud per week!
It takes work but the product can be unsurpassed! There is nothing about hydro that makes the pot better. So if you are growing for quality but think indoor has to be hydro, think again! BOG is my Advice
