Welcome @The new grower . Nice light man, Mars lights are great.Here it is everyone Mars Hydro 600 watt sunlike led. This is what the girls look like under it. About how long do y’all think it will be till harvest.
Depending on strains from seed. I wouldn't chop until at least 60 days. Clones, usually mature quicker but I still would pull it until 8 weeks. ( having a scope looking at tricks will help)
I would recommend brother next grow cycle is to Veg your plant for about 6/8 weeks and then flip your lights to 12/12. This will increase your yield and potency. That would give you the most bang for your buck. Hope this helps
