Outdoors and stretching

Hi - i found through this website how to correct an indoor plant that is stretching - BUT how do you correct an outdoor plant stretching - i cant move the sun any closer than it is. - plants are in a small greenhouse - look very healthy but are 4 days old now and are about 7 cm high....

sun is hot in my climate - should i move them in the shade for a while ?

best advice anyone...

The plant may be stretching due to the heat.alot of sativa naturally have long internodal length, you can prune the growing tips to keep the height down.

You should start your plant inside so this doesn't happen. When established move outdoors.

You need to put some lights on those babies and a fan. Shade clothe should be over the greenhouse at least so those babies don't get direct sun light. Try some cfl's about an inch away with a fan blowing directly on them. Your only hope. Or your could just bury them so only about 1/2 inch of stem is showing and start over.
