Mars Hydro TSW 2000- Height and Dimmer settings for the various stages

first of all good luck. I am using the same light. after placing the seed in the soil; veg. period: 1st week 37.5% 2nd week 50% 3rd week 62.5% 4th week 75% flowering period: %one hundred from start to last week I use single height 41 cm. good growth.

Hey buddy. I can send you a chart I send every1 who asks this. If u want just DM me. But here it is. 30cm distance from the canopy to get the highest number of your ppfd as even a 1/2 higher than that will drop your ppfd by half or close to that. For 0-1 wk Seedlings 40-50% veg 70-80 and once stigma starts iI like to keep that extra boost in light for flowering so turn up to 100% when pistons show. Good luck buddy.

Less light intensity is better in vegging it promotes more growth. I do a perpetual auto room and I keep light at ceiling. Vegging plants stay lower in room and flowering get boosted up on crates if they don't get tall enough. My light runs 100 percent every day. So you can dim or move further away depending on situation. Your leaves as they grow will tell you if light is right. I shoot for a perky leaf that is out and up more is a sign light is right. Droopy is likely getting too much. Excess stretching is not enough.

This here is a powerful light. I am using one now also. When I first received this light I was getting signs of some light stress so after w couple of rounds I found that this is what works for me. For the seedlings (weeks 0 - 3 stage I have mine about 20 inch away @ 65% power. After 4th week it is fine to leave the light 16 - 20 inch away @ 75%. I leave it at this until the 4th week of flower I turn it to 100% @ 12 - 18 inches from the tops of the plants. 100% @ 12 inch sometimes gives some bleaching so be aware. Anyways I hope this helps you on your journey with your new light. Never stop growing ✌️🏻😎💨
