Spider Farmer SF1000 or Mars Hydro TS1000?
What would you recommend between Spider SF1000 or Mars Hydro TS1000? Both seems pretty similar, which one to chose? I’m planning on growing two autos at a time/or one photo, 70x70cm space.

Lux Meter and Hydroponics
Who has experience with using LUX meters to position lights in various stages of hydroponic growth. I feel I am giving mine too much light, based on the readings, but don't want to pull them back. Currently 10" from the plants.

Starting photos indoors for June transplant
Want to start photos on a 14/10 schedule in April to match the lights around June 1st. Can I grow my babies on a 14/10 indoor schedule or could that possibly induce early flowering? I would rather not slowly adjust down from 18 to 14 before Xplant as suggested otherwise

Swapping day/night light cycle during flower
Day 22 of flower. Lights are on during the day, 8am-to-8pm but we need to switch to 8pm-to-8am to use the colder night air to cool our lights without using a/c. Would it negatively affect the plants at this point in flower to give them 24hrs dark & completely swap light cycle?

Plants Growing Taller Than Light
My plants are growing taller than the LED light! The hanging wires that came w/ the light are now too long; even after rigging the wires so the light will hang at a higher distance. I am using a 4 ft. tall grow tent. How/what can I use to adjust the height of the light?

Found a cheap light that I think would be perfect in my small tent, would it?
Would this light be good to add to my setup? (60W 55 draw cob in a 40x40x120cm tent) ://i.imgur.com/VTayXRu.png 4500 Lumen 4000 or 6400 Kelvin 50 Watt (I already know there is much better, but know I am asking about this one)
