Heres some nice pre-filter options or you could use them on the intake side. I like to put the tent up on a base to help ease the back. Also the drain pan really makes things easy. I use a 10g garbage can under the tent with a sump pump in it sending waste water to my sump pit.
How do you think the 3/4 pvc would do supporting 5 gallon pots? I’m thinking a 4 foot span with legs at each end and then at 2 feet.
2 pots total.
I love this rack. I will be doing one in the near future. Thank you for sharing!!
You might need to put together rack kits and sell them.
