Not sure if it's just my imagination or what....But the Bulb on my MH Light blew 2 days ago so I've just been using LED's the past 2 days. Seems like the plants grew almost 2" according to the stick I have in the ground for support. Maybe I'll still use the HPS Bulb for Bloom ??? Not sure. Think I'll invest in an LED Hood Light....Any suggestions on what watt I'll need for a 2' x 4' x 6' tent ? My plants are currently 2' tall & just transplanted so giving it till the weekend to recover. Then I'll start the Bloom phase. Any tips on Bloom will be helpful as this is a 1st time grow. Thanks........."Party On"
