OK, I'm doing my second SCROG - Larry OG from Cali Connection. Feminized seeds.
Seeds: Larry OG (feminized) from Cali Connection.
Grow Medium: Sunshine Mix #4. I added 2 tablespoons of dolomite lime per gallon, and a fair amount of coarse perlite.
Grow containers: 5-gallon Smart Pots.
Nutrients: Dyna-Gro 2-part (Grow, Pro-Tect) mixed exactly as the bottles say. I use only tap water, and I don't ever balance PH. All my grows turn out fine this way. But I draw the tap water into 5-gallon buckets 24 hours before use, so as to allow the chlorine to evaporate. And my tap water is very high quality.
Grow room:
A 32" x 32" x 60" tent under a Sunblaze 2-foot 8-bulb T5 fixture (for vegging).
When it's time to flower, I'll use a 400-watt Hortilux HPS bulb in a nice air-cooled hood. I use a Lumatek digital ballast.
My SCROG screen is 29" x 29", and is 9" above the tops of the Smart Pots.
All 6 of my seeds germinated just fine using the "soaking in water" and then "paper towel" method. I raised them in 18-ounce Dixie cups, and transplanted them into 5-gallon Smart Pots.
I chose the best 3 of 6 seedlings for the SCROG. Maybe I should have went with just 2 plants, but using 3 plants means I can switch to flower sooner.
Here's a pic taken today:
