I think DIY is the way to go on a budget and either a set of quantum boards or bridgelux eb2's will get you an inexpensive build.
3x3 tent = 9sqft @ 40 watts per sqft = 360 watts for flowering
A set of HLG quantum board 132's($125) with a HLG 320h 36 ($86)driver will do your tent perfectly at 300 watts when driven at max.
Or 16 bridgelux EBb 24" ($7 per strip or $112 together) strips with an HLG 480h 24($130) for a total of 480 watts that you never have to drive at max
The strip build will cost a bit more to build the frame but it will have more power than the quantum boards and could be used in a 4x4 tent if need be. Plus the light spread will be amazing compared to the cobs or quantum boards.
Im currently investigating a light for my new 4x4 and this strip build sounds interesting. Can you tell me more? Or link to a decent guide thread for this?
