Ok not to step on anyone’s toes but IMO if you are new to growing the last thing u need is a par meter.
Starting growing can b expensive enough and there are plenty of other things to spend money on. Unless your resources are unlimited I would not bother with a par meter. Here’s what you ask yourself, what will you do with the info it gives you? Will you choose to buy a different light? Will you move your plant 3 inches to the left? Does that make it worth the investment? Or could u put that money towards something like better air flow or better lighting or anything that will actually make a difference at the moment. Until you’ve reached a level to put to practice the info your collecting with a par meter it is a waste of money for a brand new grower. Again, this is just my opinion. Take it for what it’s worth.
