well this is my second indoor grow i use one sonlight agro 400w hps and i grow 9 super skunk feminized plants in 1m2 currently week 2 flower .my problem is that the plants are getting too big and in order to keep the buld away enough from the tops i will soon need to get rid of the roof of my grow room.my plan is too get them outside for 12 hours since there is plenty of sun light at this time and the weather is generally good and then get them back i the grow room for the dark period.is this going to cause any problems to the plants? do you suggest me to do it or not?has anybody tried this before?
