Start at 36"inches and work your way to 18" as the plant grows.

Changing Lighting Schedule
The days on the plants are since planting, so i was going to keep the vegetative light schedule until 5 weeks since planting, then start moving towards a 12/12. Is it even optimal for an autoflower to have a traditional 12/12 lighting schedule during flowering?

UV light
Where exactly should the uv light be placed? Is it possible to place it between two spotlights? Or is it better at the ends of the lamps? What uv light do I need for a space of 1m2? I'm very lost, help please! Thank you!

Anyone affiliated with Mars Hydro? Very disappointed with customer service
My TS 1000’s controller/driver crapped the bed. Contacted customer support, told them the issue, they diagnosed based on videos i send, and was told they were sending replacement parts. 2 weeks later, no email confirmation and no reply to my previous 2 emails sent a week apart.

How to get a new led light from sponsor
I need a new led light. I'm trying to get some from contests but it seems quite difficult and sometimes the awardees seem to not always be the best. Does anyone know how I could get a light from a good sponsor? Thank you my growmies! Hope everything is ok with you (=

Added a light, how far should I hang them both from the girls?
I have added a Mars Hydro TS600 to my tent along with the Spider Farmer SF1000 in my 2x2, how far should I move them up away from the plants? I'm guessing I don't want them as low as the SF1000 was on its own which was around 15" Thank you lovely people!

How to grow Jack Herer and Power Plant strains
Hey growmies, I’ve started two Jack Herer fems and a Power Plant fem on my 3-D’s diary. I’ve read JH can be a mofo and should be grown on a 12/12 light cycle from seed. I read the same for PP also. Is this true???? I’m trying to maximize yield. Thoughts please… 🤯

Effect of light only? Really?
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

Information on led grow light.
I am growing one plant of OG KUSH AUTO strain from Nirvana with light setup of 200watt of white led flood light and 300watt of led grow light. Is this much light enough for a single plant? I am using soil as grow medium.
