how many plants can I grow in this amount of space? I am thinking 2, is this too many or can I manage more? What kind of yield can I expect with a unit like this, and how quickly...I've heard scrog takes less time.
any advice is appreciated![/quote]
1) Any projections anyone gives you on yield is pointless, there are too many unknown variables such as strain being used, veg time, etc. I have seen 5 ounces pulled off of a 3 plant scrog that was flowered under only 300 watts of HPS light in a DWC. But the grower was an expert. My first grow was 2 ounces off 6 plants under 400 HPS of light in soil. Projections are just that, projections, they mean nothing.
2) 2 is fine, and yes you can do more. I do 9 at a time in a 3 square feet of space that is only 3 feet high, simply flower when the plants are still very young. Again, other variables will have a huge affect on this such as whether the strain is indica or sativa dominant etc. If you are unsure exactly what strain you are working with then it will be trial and error.
3) Scrog will not take less time. Nothing will make a plant flower faster other than altering its genetics. A plant flowering under 12/12 light takes the same amount of time to finish whether it is in soil, DWC, or any other grow technique. Just remember that if you are going to do a SCROG you will want to ONLY use clones. If you grow multiple plants from seeds and then weave them into a SCROG you will have a problem at the end because all of the plants will want to finish at different times. Even seeds from seed banks are usually F1 generation seeds that show variable characteristics.
