the plants are sittign on the floor in my closet. they r on top of a carpet and towel. it gets cool here during the nites but not bad. the ph is aroun a high 7 and has been there since i began the grow (bad soil) and i have only been watering it about once a week or every 7 days. so you are saying to switch to the T-5? and i cannot really bend or tie the plants anymore because the stems r too stiff now because it is flowering. there is no way i can fit both lights in my closet at the moment so its one or the other...
