LED Growing light for my homemade grow box

unk83 · Oct 17, 2016

Hello.

I am planning to grow two (2) White Widow autoflowering plants (datasheet: https://www.royalqueenseeds.com/178-white-widow-automatic.html). Soon I will start building my growbox. Estimated growbox size: Length 1.10m x Width 0.35m x Height 1m+. Total surface: 0.4m² or 4.3ft², rectangle shape.

What LED grow light(s) should I buy, for the above setup, without spending a fortune? One big in the center or two small (one above each plant)? For both growing and flowering stages.

While researching I came across some LED grow lights and I am thinking about the next four options: a) 2x GalaxyHydro 300W b) 1x Mars II Hydro 400W c) 2x Mars 300W d) 1x Platinum P150 250W.
What do you think? Any other opinions?

Thank you.

for that size space you would get better coverage with 2 lights but with you limited height you may not be able to get the light high enough above the plant to get full coverage and may end up burning your plants. perhaps led strip lights like these would be a better option http://www.digikey.com/product-detail/en/samsung-semiconductor-inc/SI-B8V221B20WW/1510-1413-ND/5992246. or DIY CFLS.
