I'm going through a first grow (supervised by experienced members) and learned a ton about these ladies .. my seedling started with a Home Depot LED setup... I thought I was it.... lol, then they out grew that, so I jumped on an upgraded 150watt setup...they out grew that...then I jumped on another 150 watt led...they out grew that one...so I went to a 300watt LED setup......and yup...they out grew that too....now I'm mid flower with two 300 watt LED fixtures with one 150watt fixture in the middle.. lmfao... just spend for a decent lighting that will cover your space and light it up well into flowering, they last for multiple grows, over 5 years is what I'm told if you take care of them, some have over 5 year warranty, so that upfront coat will pay for itself in the long run... just do your homework... PAR Charts is something to check into for each light your considering.
