Is anyone else using Spider Farmer Lights ? How was the stretch on your plants using these lights ? My plants stretched from 10 inches to 30 inches in two weeks & another week of stretching left.😒 Not a big deal but I have a 60 inch tent , not a lot of room to LST.

Too much lighting?
Too much/too many lights? Getting all popcorn buds/low yields. Getting a light meter this week. Going through by process of elimination on how I can get better grows. Read the manufactures instructions, but not good with technical electrical/lighting terms. Thank you.

Wrong power cable in my LED light: still light when switched down off.
Have you ever made this mistake? My second harvest was someway worst then my first. Sure I did some watering mistakes but during my chores in the room and in the tent, I found out. I used a random power cable on my PAR LED lamp so when It turned off still had some light on. Bang!

1 inch seedling under a humidity dome sprayed with water in a 24x24x36 Vivosun tent. I’m using a mars hydro ts 600 watt led which is 21 inches above my seedling (small tent). Do I downgrade to my 150 watt ufo light until I can do LST? This mars led is definitely warming up things

100W full spectrum enough for 2 plants in a 80x80x160cm tent. Should I get a 300W instead?
So, I bought this light, it's a 100W full spectrum grow light. But I think I might've bought it too hastily. I want to ask you guys before I return it though. Do you think I should get a 300W instead? Planning on growing 2 auto plants ScrOGed.

Marshydro FC oder FC-E
Lohnt sich der Mehrpreis der FC Serie im Vergleich zur FC-E Serie? Auf dem Papier ist der Unterschied ja eher marginal.

Have to hide my lovevly plant, what to do?
Funny question, my landlord has to come over to check some stuff in my flat. I'll obviously have to hide it but it will change the light schedule, it's gonna be longer in the dark (probably around 3hours more). Is it a problem? Can i hide the plant somewhere without hurting it?
