Too early to turn up the dimmible LED light on my seedling?
Unsure if it's too early to turn my light up just yet or wait till more leaves are growing. Currently at 25% (10,000 lux aprox.) using the dimmer for a 120w LED at 20 inches from seedling. Thanks in advance.

Looking for unsponsored responses... need light...my car cost 1000$ and I can't justify anything close to that. Flowering a 4x4 area..should I wait for tech to develop and HPS in the meantime? Convince me otherwise with your experiences! #budget

My grow space is 46"Lx67"Hx24"D. I have a dimmable 1000w mh and will switch to 1000w hps soon. For this size space, how high should I expect to have the 1000w? Is 100% too high? Pic is older.

Throw out one plant?
Is it productive to kill one plant if the rest of the plants are filling out the room just fine and to promote ventilation and light penetration? I have one plant that is way shorter and behind the others due to genetic problems.

Been running my lights 24 hours a day on my seedlings. Since I am growing autos, should I be at 18 and 6 now? Or should I keep running them 24 for the first couple of weeks to help veg up little before giving rest? This is my 1st time growing autos and 1st indoor grow in 20 yrs

Plug timer running fast
My plug timeris running about 10 fast each 24hr. And is now at about 2 hours past the actual time. This causes the light cycle to shift forward slightly everyday. Should I set it back to the correct time, leave it be or buy a new one? It is plugged vertically in wall socket.

Add on lighting
Hey Growdiaries. I’m about to start my 2nd grow but I’m 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 I’m only growing two plants in a small w3xd2xh3 ft tent. Any advice plz & 🙏🏼
