Just ordered 2 t4 1750. Excited. You suggested three lights for my 5x5 but I recently incurred a medical expense that lowered light budget. If I were to only use 4x4 of my tent on six plants will I still get the 830ppfd? I purchased the ones with reflectors, should I of waited for two with lenses to come available? I apologize if these are dumb questions, totally new here. Thank you for your time
2 T4-1750s and 1 T3-2100 would provide 740 PPFD.
3 T3-2100s would provide 670 PPFD.
Any of those would provide excellent results in a 5x5
