- Product Review (submitted on June 4, 2015):
I am giving this a 10 star rather than just a 5 based on the customer service of Inda-Gro, top notch
I have many of their fixtures, the 420 and 100's.
The 420 will perform solid from seedling/clone all the way through in a 4x4 no problem. I can see 5x5 if you rotate and move your plants around.
If you can swing it definitely add the pontoon. You will see earlier ripening and even more density in your flowers!
You can cool/vent a box or tent with the 420 with just a single 4" exhaust fan/filter combo
100% recommend this product!
