IMO no need for Airstone but I get the concept. The reasoning behind not needing it with a larger pump is u are exchanging and fully aerating the rez every thirty minutes or so with an hd air pump. What this does is as the water runs over the hydroton it becomes surface water which is highly aerated hence no need to run an Airstone. But to San his own I'm sure it works great. I just drill a gang of extra drain holes and add high output pump and voila beast mode growth lol.Ah, got it. Ok, let's see how she does at only 12. You may have issues down the road, but sending good vibes bro. As Kap said, upgrading the pump is a must. The stock pump is shit and loud. My waterfarm's are modified and the first thing was a high output pumps (min 40-60 gal), dual output (to feed airstone in res).
Will be following your grow to the end brother.
Hey Kaptain, I would totally agree with you if I was using HID. However, with these LEDs, im sure you know about the penetration issues. I am seeing penetration issues right now with my current grow. The bottom branches are considerably less developed than the higher branches. This exists with HIDs as well, but I feel like with these LEDs, the different is bigger. If you saw how I setup my current grow, you would see that the short bushy plants are in the direct middle of the lighting, and the sides are filled with tall colas. This creates much more efficient use for lighting. If the entire canopy was an even level, like a scrog screen, then the corners of the plants would not nearly get as much light as they would if they were raised closer to the light. However, you are totally right about the angle of my screen. It is too high, I wish it would be like 30degrees lower... I will play around with it and get back to you!My opinion is though that your screen may to extreme on the vertical plain IMO I would vary the outer edges no more than six inches higher than the center height for ideal light spread. This is just an opinion though.
Aw, now, don't do that! The poor guy just told you he can't have nuthing vibrating!!! LOL<...snip> ...but sending good vibes bro.
