Effect of light only? Really?

Rush2112started grow question 5 years ago

These girls same strain (strawberry cough photo), born on same day, same medium same feeding except the one on the right was removed from the light about 3 weeks ago and put outside. I thought dark green from nutes, seems the light alone makes such a difference? 45 watt LED

Can just be genetic. I'm running two runtz from seeds and they both look completely different in every way. One almost always looks sick.

LED light intensity So can anyone tell me from experience what are good light dimmer settings and height above seedlings for a SpiderFarmer SF7000? And for the other stages of life would be great. First time using LED's and don't want to fry my babies, I used to use MH and HPS lights.

Need to upgrade grow light I'm looking to buy a stronger light for around 200$ that can adequately cover a 4x5 space for veg/flower. I've been researching for weeks but can't decide. I'm currently running with two TOAD LED Grow Lights 600W, actual watts 85. They are Blurples. Any suggestions?

18/6 leads to high temps in small tent; change light schedule or stick it out?Girls are at 18/6 and 3-4 hours before lights out the tent gets up to 90 degrees and humidity can’t compete. Should I wait it out or try 16/8 moving towards 12/12 close to flowering (autoflower). Will lowering light exposure affect yield more than high temps would at 18/6

Gradually prepare for the "SWITCH"Hello all! What is your way to prepare plants for the switch in terms of light? Do you reduce hours of light slowly until the day of the "switch"? Do you gradually push up the power of the lamp? At this time i am giving my ladies 24 hours of light, lamp at about 25% of power.
