Schould i buy another more expensive lamp with more watts or can i just buy a second xs 1500 ?
Dopacks
started grow question 4y ago
Does it make sense to buy another Viperspectra xs1500 with 150watts? So my question is, if the power of 2 same led lamps add up together?

Yes both together would equal 300 watts. Add another it's 450 watts..

As hempkid said. Also the beauty of having to lamps is if temps get to high you can turn one lamp off to cool down then when that comes back on you could turn the other lamp off.

Setting up air cooled refactor.
I've got a new air cooled light refractor, a tube like one. I've set it up such as the pic, I'm thinking of putting the extractor where it shows on the pic with the air flow going the way of the arrow, would this be OK? I can't find anything online about setting this one up.

How do you use plant LED lights? I am using the BESTVA 3000, which has separate growth and bloom lights. After flowering begins, should I use both the growth and bloom lights together, or only the bloom lights?

Lighting schedule?
Many references state the when moving from vegetative to flowering stage the lighting schedule (indoors) needs to be reduced from 18-20 hours down to no more than 12. Why do many here stay at 18 or more the whole way through?

Hello fellow growers :D thx a lot Firstly, is the reason why my plants (especially cookies) are very slightly curling/folding at the ends of the leaves because the LED is too powerful?(Reason to be worried?) Secondly, should I start adding nutrients? Just 1/4 of Bio-grow for now?

2 plants, 2 Mars Hydro TSW 2000’s, need help with pot size/tent size configuration
My plan is to flower these 2 girls in a SCROG under 2 Mars Hydro TSW 2000s (2x300W actual). I’m debating whether to flower them in 5 gallon plastic pots in a 2x4, 10 gallon pots in a 2x4, or 10 gallon pots in a 4x4. Does more area = more yield, or am I thinking about this wrong?
