it's not a question of spectrum with this light because of the white light, so it's just intensity and little seedlings can get stressed from too much light - best to avoid that and slowly increase the light intensity. Hope this helps ! 🚀
Hello Fellow Growers.Have lst this plant bent her over and trained the branches out to open her up.Have done this several times now.I never topped her and as you can see the main cola has stretched way above the canopy.flowers are fairly small..Any suggestions for next Grow.👌
Heres a late thought on your lighting question.
If you have the option to raise the light I would run it at 100% from a farther distance. In my experience it works really well. I use an easy cloner with 4 High output T5, Plant into peat/perlite mix when roots are healthy and 2 or 3 inches long. These go under a 600 watt hps with about 4 feet between the plant and bulb. They stay there for 2 weeks and move to 1100w hps about 4.5 feet away and love the transitions. I dont recommend using lower wattages for veg, I think it will only slow growth down.
The photos look like you made good decisions, your flowers are starting to set nicely! Remember these are only thoughts. I always suggest you do what seems right for your setup, and most important always try new techniques one at a time. If you try everything suggested to you you'll have no idea whats helping or hurting.
@FishTickle, Thanks for your suggestions.I have found what I think is a good distance for my setup.I have the Mars set on full power and have just used the Manufactures suggestion re;Distance from plant.Being my first grow It has been fun learning.Only had a few issues so far that were easy to rectify.Slight Veg nute burn and a small amount of cal/mag Defficianc and had some temp issues for a few days (Too Warm).All travelling well now.
