Do not switch back your lights to anything more than 12 hours or your photo period plants will respect that photo period and go back to vegging stage. Keep on the great care! Happy smokes!

Lamp for houseplants?
My neighbours fiancé yesterday evening dropped by and gave me the lamp on the photograph, I have no users manual, but I understood it is for houseplants. I wonder if it is of any use and how I can use it. Whenever the sun shines I will put the plant in the sun of course

hlg550 distance from canopy veg
How far from canopy for HLG 550 during each stage? After starting with a cheap LED, without getting a par meter I think 18" @ 50% power, or 32" @ full power for veg? Start higher and increase power every few days?

Light for 4x4 tent?
Which would you go with for a 4x4 that is used for veg and flower: Mars Hydro TSW3000 or AC Infinity s44? I've got myself narrowed down to these two options.

Will the change from indoors to out trip my plants into flowering?
Hi, Guys, I plan to move my plants outdoors next week. Will the change in the light schedule trip them from veg to flower? I really don't want this. They're currently @ 3 weeks on 18hrs indoors and outdoors they'll be getting 11hrs direct sunlight. Also, they're photo's not autos
