Add on lighting
Hey Growdiaries. Iโm about to start my 2nd grow but Iโm not happy with my Viparspectra 300 for flower. I want a cheap add on for the flower stage? CFLs look like a cheap, low energy use, add on as Iโm only growing two plants in a small w3xd2xh3 ft tent. Any advice plz & ๐๐ผ

Autoflower light schedule
Soon rolling into veg for my first auto grow. Currently on an 18/6 light schedule using Mars Hyrdo II 700w . Donโt have any problems with temp/humidity inside tent. Once you notice the buds starting to flower do you switch to 12/12 or just keep plugging away with 18/6?

Worths investing?
Thinking to upgrade my grow with 4 x 15w led bars. 1 on each corner of the grow room, vertically, as secondary lighting to a 400w hps. Does it worth the investment? Price vs yield?

I've been running the light 24hours and then turning it down with the dimer while I sleep because I'm worried about temps Would I be better changing over to 20/4 or 18/6 or should I wait til it goes into flower? Sorry I'm a complete noob

How to reveg plants after preflowers by the end of april outdoors?
How big are the chances to bounce the plants back to veg after preflowers by the end of april and 14h of day length? Mostly cloudy weather, warm day temperatures (30c) and cooler nights (8c)in the old greenhouse simulated probably to much end of summer vibes.
