Scrog is a great way to grow. but as hilppe says it works better if you know your plant.There are numerous strains out there that work well in scrog .Power plant. white russia.aourora indica and i think nothernlights would work well with the sgrog method .You want to start trianing in veg either under the sreen or lst until you drop a screan over them .I have done white russian and aurora indica scrogs and grew both strains normaly and they defenetly produce far better in scrog imo If you start lst in early veg you can splay the plants and get them all bushed out before the screen goes over i found this helped massively.dave
