Hey F & D growers
I just made a change to my f & d tote system. I have to use individual small totes with lids. as I have a mosquito problem ~ 6 months each year.
I've been trying different things instead of air stones for adding DO to the nutrient solution. For my last 3 grows I added a second, but small gph low pressure pump to each rez It's on a separate timer.
Nutes are pumped into the totes through a separate pump and floods each tote through a simple marine bulkhead: the portion inside the totes is just a ~ 1/2" opening. Each tote contains ornamental stones. As the solution is pumped in, it flows over the stones which MAY create some additional aeration, BUT, I recently noticed the flood fixture for f & d tables has a screen (see pic). I purchased 10 of each and will see whether they help increase aeration. I may need to add a bigger gph low pressure pump to push the solution in faster. Thoughts?
