Lighting For how long is 2x18watts enough?

Hello there :smoke:

Im doing my first autoflower grow at the moment and my seedlings are now 6 days old. They are currently inside, under fluorescent lights (2 x 18 watt). When they are old enough they are going outside for the summer . I was wondering for how long i can keep them under the few 36watts and still have decent growth. Dont want to waste any time with these autoflowers

Btw, im growing some freebies. WOS northern lights x big bud

Thats really not enough lighting so try and add a few more lights if you can.They should be at least a couple weeks old before you put them outside.

Aww, i really dont have other lights right now. The weather is nothing but rain the next week. I have placed the lights very close since they dont heat up at all.
Is a cloudy day with clouds blocking the sun better than the 2x18watts?

If you can put them in a windowsill aswel as the lights that would be best. And it probably is still brighter on a cloudy day I was shocked to find the light outside on a dull day is more intense than a 600w hps a meter away
