hey buddy some mighty fine bush youve got there : ) personally, i reckon your better to do the training earlier on. im not sure about super cropping tbh, never tried it but theres nothing wrong with lst at any stage if you can just tie it down? i train mine every other day till the bitter end. but if you start it earlier then you will always be able to have the lights a lot closer and better light distribution over the canopy. this means the lower buds can all get a lot bigger. ignoring the wee one, the left is a/u wich is a 5-6footer if you leave it to grow. shel hopefully be kept under 2 ft as thats about as much space as ive got.
