im planning my first grow, kinda tight on cash, and i would like to know the cheapest way to get the most light. im looking to start a perpetual harvest and i need enough light to harvest 3-4 oz a week. i still havent decided how many plants i want to grow but i know i will harvest more if i grow more plants at a faster rate, so im thinking about doing that. its going to be in my closest where there isnt much floor space, its something like 4x6. ive already bought a few 50w cfls but at 10 bucks a rip and even more cast for a light socket im not sure if i should buy more or save for the hps system.. any ideas?
