Need some growing advice.. I was looking into Hydro Grow Boxes/Cabinets and was wondering if a 4ft Cabinet would be ideal or big enough for growing 2 Indica plants at a time. Would it be tall enough or would I have to do some kinda of tie down training method? Keep in mind I would have a basin for the water and light on top, not sure actual grow space I would have with those. If anyone can help me out I would greatly appreciate it.. (Not a fan of Grow Tents, stealth is key for me)
