For bloom I would use both. the more light without burning them the better. Everyone I know that has a burple uses both.

Wow. Thank you so much for the reply. I have been playing with LUX meter app and my light. I was bit skeptical about the lumens that I would get from the 15W but as it turns out, it receives well enough ppfd. Still skeptical about the spectrum i am having.

MARS HYDRO TS600 LIGHT STILL ON WHEN TIMER SWITCHES OFF
it is a known problem i found 2 forum posts discussing it. Different timers have been tried but it always remains the same. Someone said with a mechanical timer the problem is solved I will try that as soon as I have one. In any case, this is absolutely unacceptable.

Bad idea?
Will a mars hydro TS1000 be too strong for a 60x60x140cm tent? I have been using a TS600 and TS1000 in tandem in a tent 4x too big for the light level, I have been growing strong and tasty buds but with low yields so downsizing my tent size to maximise the light.

Should I flip?
I’ve got my plants in 2gal fabric pots and I’m not planning on transplanting up. The plants are averaging about 8/9” and I’m starting to see small roots out the bottom. Should I flip to flowering, or can I get away with another week of veg?

What are optimal PPFD
Anyone have a quick and easy rule/suggestion for PPFD & lux for plants in Seedling, Vegetative & Flowering states? Lots of divergent answers online. At plant top right now I'm currently at ~1000PPFD and the lux readings are 49,000-51,000. What are 'best practices' for this?

Do I need to lower my lights?
Do I need to lower my lights? I'm using a Kingbrite 240W Samsung lm301h and I just went into flowering period. I think the light is a bit overpowered for the room, so I've left it at about 21 inches above the tops of the plant. At this distance, all areas are getting 27k lux.

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.

Does this look ok? I have 2 plants not growing as fast as my macchiato plant. The other two are different strains, Runtz & Zittles. I don’t want to over do it but I know light is key so I thought I’d ask. Both 1000 watt uv & the other is led. I’m on veg week 5 of all 3.

LED Kelvin Temp 3000k-6500k
Is there a massive difference in colour temperature/kelvin of LED's if the lumens, PAR, watts, intensity and every other aspect you can think of is the same but its temp/kelvin is lower? I use a 6500k LEDs, may mix in or switch to 3000K for better flowers if its proven to work.

Cuando y como pasar mis plantas a floración??
I'm going to switch my plants to flowering 12/12, I've read that they leave them without light for 48 hours to force flowering, is this good or should I just skip it?? And I have a dimmable ballast, I have it set to 400w, when I switch to 12/12 should I set it to 600w or wait until the second week of flowering to change it to 600w??

Grow lamp setting veg or bloom or both?
For my grow lamp settings this early on should I be using the VEG And Bloom spectrums simultaneously? Or just leave in Veg? Since these are Autos I wasn't sure if switching the spectrums was as important as maximizing light.
