lol actually the earth does change the degree of tilt on its rotational axis as it travels around the sun and this is exactly what changes seasons during summer the northern hemisphere is tilted closer to the sun and the southern is further away this is why on christmas day for example in the uk its freezing but in australia you can sit on the beach in the baking heat. and those on the equator have a more stable temperate range all year round.

Sorry, darkdestruction, that is just nonsense, the sun´s spectrum doesn´t change with seasons. The sun´s colour temperature is a constant 5600K. Because the mostly naive kids who grow MJ will swallow this garbage is the reason we get so much of it.

And the doppler effect is the change in frequency of emitted radiation according to whether the source is moving towards you or away from you.

Obviously you have no scientific training. And don´t try to BS a Physics teacher unless you are very sure of your stuff.

You think I don´t know that?? Doesn´t appear to be relevant to anything you have mentioned before.

The sun still has an unvarying colour temperature of 5600K.

back to your comment about the doppler effect as the earth is moving on its axis this has a smiler effect to if the entire earth was moving closer and further away but as this is not the case and its only moving on its axis in effect one hemisphere is moving away from the sun and one is moving towards it however slowly happens it does happen.

It's 2 weeks under the MH - Roadrunner strain (auto). I may keep them under the MH all the way to the finish, but I have HPS for change if needed. It's my first grow so have 0 experience.
