Short plants in flowering
Flowering started but the plants still seem a bit short. Maybe too much or too close light? Or something else? Tried avoiding light off because its hard controlling the rise of humidity.

Stretchy seedlings...worried!
Hi, I have 5 seedlings on day 7. 2 of them are going fine but the three from ditch passion were very stretchy though. Likely due to having the light to far away. Take a look, any advise would be great. Cheers all!
