@cmokemtl, trial and error my friend trial and error. I've done about 7/8 runs in my time. Always a 4 week veg, my current diary: vegged half the room for 6.5 weeks and I've never had such nice plants personally myself. So from now on i am always going longer veg. In saying that I am currently switching all my tents over to hydro which is not only a learning curve but I'm already about 1500$ in material and I have nothing put together yet 🤣 looking forward to seeing these finish. Your grodan blocks have given me ideas 👍
