Mars Hydro are one of the absolute best "affordable" lights. Especially for what you get for your money. I have the Mars Hydro TSL-2000 and just finished my 1st grow ever and pulled 1 gram per watt even with all the mistakes I made. The only thing about the light that I dont like is that it doesnt have UV light but it does have IR. The TSL-2000 is a quantum board light with a 16 band spectrum that is the closest thing to real sunlight you can get. Genetics are obviously the most important thing but the light you get to grow with is a close 2nd. You dont want to skimp on that. I got lucky and waited til Christmas to buy mine and only paid $212 for it... Right now they're going for $250 on Mars website. But getting about 300 watts true power for only $250 is an awesome deal. And dont let anyone tell you that you cant grow top shelf, high quality bud with Mars Hydro lights bc that is complete bs Not only were my buds completely caked in trichomes but the buds were also very dense and super colorful. With the quantum board, 16 band spectrum lights they have a much easier time pulling all the colors out of your plants. I've seen people spend 2 or 3 times that amount on a light and didnt even have as good of quality stuff. For the money, Mars Hydro is where its at
