Two LED 300w lights for four plants?

[leohowe3]

Hi all,

I'm doing another grow CBD Therapy and wanted to know if 2 x 300w Vipraspectra LED lights would be enough for four plants? I used one on two plants for my last grow with okay results but am thinking they might need more light.

the tent is 60 x 60 x 140

Can you have too much light and can that be bad for the plants?

Also, is there a reference guide on here somewhere to show how to do a online grow diary? want to get some advice after this next grow to improve yield etc.

thanks v much

last time you used 1x led and 2x plants, this time 2x lights and 4x plants,
so really you aren't using anymore light since the one light will still be growing 2x plants,

those panels only pull 136 watts each so it's definitely not too much light,

more light is better aslong as the environment can be kept optimal,

as for a reference to doing a diary, just post some info and pictures

People never seem to check the true wattages and end up being dissapointed.

I've grown 4 plants in the same sized tent, using just a Mars II 400w (real draw 180-200w). There's no room to add another light for me. I don't know the dimensions of your lights, but my main concern would be the heat generated. Can/will your set-up be able to cope?

yeah was thinking that the light wasn't giving out 300w in total. Will get the second light and see how it goes. The heat generated from the lights is very low and my environment is stable temp/humidity wise so should be okay.

okay great thanks, 'll track my progress and start posting.

Cheers mate

how do you go about finding the true wattage? I can't find that info anywhere (not on the website, manufacturers guidelines, instructions etc)

would be useful to know for sure!
