Filling your room with 100 watt fixtures for 100 plants just seems odd. You have a good budget, you can buy some good lights. How big a space you got to work with?

got some spaces to chose from but about 200-300sq feet got some smaller and bigger rooms to

would fewer 600w lights be better

I would defiantly think so. I like HLG but there are many cheaper alternatives that work just as well. @bk78 deals with Meijiu lights, I believe, from Alibaba that do a great job and will save you a ton of money. I would be looking to go that direction if I wanted to light a large space like you do. I would think you could light that space with much fewer lights and buy a backup or 2 well below your budget. Perhaps BK could guide you a bit on that.

Thanks for the help dude. my only problem is that i live in the eu so shipping and stuff would cost me a lot. one more question. https://marshydro.eu/collections/ts-series/products/ts-3000 these are the lights that im looking at now. 600w led. if one lights Coverage is 5 x 5 ft= 152cm x 152cm then why wouldent 8 of these be enough for a 20sq meter room??

That's a 450watt light. not 600. 5x5 would be for veg not flowering. You need around 800watts for flowering in a 5x5.

ye but it says it replaces a 600whps while only consuming 450w

Like Doug said hlg makes good lights, lm running 37.5w per sq ft. And the ladies love it, thats 600w in 4x4. 30w per sq ft minimum for flower. Preferably more than 30, 50w and up, you better know your plant and be tuned right in. These guys are in the know, listen to them, you will learn loads on here.

Yeah but they say all sorts of shit. You are on a grow site, take the word of those who do, not those who sell. Don't get me wrong man, not trying to be mean or disrespectful, but those here who grow know better. Lighting companies make all sorts of claims. I am small scale and fairly new but there are many here who have much larger grows. Reading light company claims is like reading seed breeder claims about when plants finish.

Your lights are dependent on your canopy square footage. The 100 plant thing confuses me. 100 plants can take up one space or 4 times that space, depends on what you do with them. I assume you are after a goal of a certain weight per harvest, would that be a fair assumption?

5 gal pots or 50gal pots? Most lights cover 1 sq meter. Spider type for example l find easier to cool as fan pushes air between light bars, dont run as hot either imo. Id go with 800w to 1000w 10 bar lights over each 5x5 area. That would treat you well imo. Anybody else on this?

I stand by my assessment of the situation.

Like @PJ Diaz said, 800 watts for a 5x5 canopy is 32 watts a square foot. That's a good aiming point. I am not experience with these large areas but I would assume you will need some kind of air conditioning no matter what.

so i used to grow 4 plants under a 300w cfl i got about 3-3,5oz a plant that way... ppl say its imposible but somehow i did it 2 times ,so my plan is to get the same amount. first i thaought of using one small led for every 4 plants but you guys say its better to use bigger and fewer lights. thats where the 100 plants come from i want to grow the same size and hopefully get the same amount but using led and insted of 4 plants its 100 plants
