No the tank is super clean with the canna a&b nutes! I don’t even use a pump I just stir it once a day with my ec truncheon. And the trays are super clean inside so far too, no residue or film. The setup also comes with trays for microgreens and tomato spikes with wicks. I’ve seen plants started in solo cups that were never hand watered once. I’ve seen a grow with the full size bed that had about 25 gallons of BAS and fed tap water only. It’s great for me because growing in coco is growing hydroponically. Just a great rig all around in my opinion.
Nice! I've got a pretty hands off irrigation/coco setup going but the hoses and especially the drain lines are a pain in the ass. Generating enough downhill slope with limited tent height and then stiff ass hoses that want to lift up all over. I'll be following to the end for sure.
Is this your first grow with the setup?
