I would not buy these. You would need a whole lot of them to amount to anything. Be better to buy a budget growlight off Amazon.

Viparspectra LED tips
I’m looking into buying a viparspectra in the future. Which one is best for one plant? I’ve been looking at the 600W one, but I don’t know if that’s the best option for growing a good yield plant in a 80x80x160cm tent.

Currently running my KingLED 2000 with both Bloom and Veg switches on. Is this the correct time to go just with the Bloom lighting? There's no harm in running both throughout; correct? Except to the power bill of course. Any thoughts?

Boost buddy
Now with the rising temperatures, I'm reaching 31-34°C in the indoor. I use Boost Buddy, a CO2 generator through the decomposition of bacteria. Is that enough, or should I modify the indoor in some way to avoid reaching those temperatures? Thanks

Should I substitute sunlight with a grow lamp on cloudy days?
It’s overcast here today and I’m wondering if I should turn my grow lights on to compensate for the lack of direct sunlight. If so, should I drop the intensity to compensate for the additional natural light? Can you overdo the amount of light (not heat) a plant gets?

Switching light schedule for an auto and Phototype!
I'am growing together an auto and a phototype with 20/4 light circle. For my phototype is about time to change light schedule for flowering, will my auto be badly impacted by switching to a 12/12 light? Or should I move every day (same place but no light) the photo for the night?

Mars Hydro TS1000 hanging height
People with experience using the MH TS1000, between 24"-30" at 25% seems like a reasonable height to put my light over the plants in initial vegetative state at my 2x2ft tent? Thank you! :)

Luce rossa e blu insieme in vegetativa.
Do you think turning on the blue vegetative LED lights, along with the red light, can harm the seedlings? Or will keeping both buttons of the lamp on together only be beneficial for the seedlings?

Light distance and power with a 205W Sanlight LED
Sanlight told me I should use it dimmed at 80% and 45cm when in flowering. I was aiming to reach lower buds so I put it at 100% and 50cm from the upper buds. The tips of the leaves are slightly burned but no bud bleaching yet like my last run (at 100% 45cm). What's best ? Thx !
