Brilliant mate il have to go back to drawing board as didnt even think of drying/curing!! If they are started at seperate times!!. Just curious if you started them at the same time say the auto i have now started flowering about half way through week 4 so if all went smoothly growth wise ( how many weeks would you veg your photo on average?? ) could you not just switch the lights to 12/12 for the photo and the auto at this point?? This is all new to me with photos as never done one ive done a couple of autos before and always had the lights just set at 18/6 never had any problems would the 12/12 cause the auto an issue?? These are the 2 autos i did before the first one is with the ts600 the 2nd is with the hlg start to finish ( ive upgraded tent etc since then aswel
You would most likely just get a lower yield than expected with the auto if switching to 12/12. I run autos 20/4, Some people do 24/0, and 18/6.
vegging time depends on how large you want the plant to get. The main thing to be concerned about is your grow space. If you veg a plant to large you can run into the issue of outgrowing your space during flowering. I.E. if you have a 4ft tall tent, you need to leave room for the Light and fans. so let’s assume you now have 3ft of space left over. You probably should try to flip to flower before you hit a 18”. 4-8weeks is usually what people are veggin for. Just listen to the plant.
Things can get out of control fast. If you notice your plant is vigorous and going to outgrow your tent you need to start training to keep it manageable. You don’t want your colas getting burnt because they are growing into your light.
Now, if I was you…. You already got another light…and you seem pretty eager to get more plants growing…just buy another tent and you can get the best results for each plant.
