i would say bend it over or top it for space it will make it much more dense and u could get more out of it that way for space.. bend it if u cant wait too long cause if u top it has to recover from it. and get something like a fullspectrum cfl. maybe a 45w or 85w. giving u more lumens for not much more electrcity. and u will prob have to wait more liek 9-10 weeks cause with not too much light it will take longer to mature and u dont want to harvest earlier then 8 cause u will be disapointed in its high, its worth it to wait till is at peak THC content
