Hi all I have a space of 1m by 1.5m unsure on how many plants will be putting in there possibly 4 or 5?, I ideally want to use led, just want to know the correct wattage to use and brands Thanks in advance,
Off the top of my head, 1.5mx1m would be about 18sqft (right?). I wouldn't do more than 5 plants in there. But 4 would be more comfortable in there still giving you space to work etc. You don't want them too squeezed up together or they won't get good airflow. As for LEDs, you're gonna want QUANTUM BOARDS. Most people on here will tell you, nothing really compares to quantum boards and I would agree, whatever you do don't settle for cheaper lights. Horticulture Lighting Group (USA) and Invisible Sun (UK) are the most trustworthy manufacturers of quantum boards but you can also get them directly from China for cheaper as long as you're careful. For these quantum boards you want approx. 30 watts/sqft. P
