Wow, those are awesome looking plants, they look bushy and big, you will get some nice buds out of those. Careful with the day temperatures, those greenhouses can really get hot under direct sunlight. I would use a greenhouse in case of low temperatures during the day or night, if this is not the case you might want to remove the cover during the day and put it back at night.
