Autoflower on Hydro. How fast will it be

Today (06-06-2021) I put 5 seeds from Royal Queen Seeds in peat pallets. This round is just to determine if I like Autoflowers or not. I have searched for a fast-growing strain just to see HOW fast it is. I do believe hydroponics are great for that purpose. If everything goes as planned and hoped I will harvest before the 9th of august. That is my goal. There is also a freebie Northern Light from RQS in my system. This one is a bit slower and just to fill the gap. Because this is an auto flower I probably won't update as often as I am used to. 08-06-2021: 3 ladies are showing their heads a bit. Not enough though to say they are germinated. Swapped Alipanel with a 300W SP3000 from Mars Hydro. Mars Hydro sent me this light to test it against the TSL2000 but that is still in flower for about 9 or 10 weeks so I decided tot test this lamp on these autoflowers. 09-06-2021: 4 out of 5 are germinated. Turned lights on now for 18 hours. (I do believe they need some darkness). Set at 40cm@50% 12-06-2021: All 4 have the second set of leaves forming so I call it a week. Vegetation can start now.
