Yes it is an 18 gallon tote. I think I will try to scrog. I have been changing the water and nutes every 7 days. I assume I will need to continue to do so all the way through flower. How do I do this once I put the scrog net up? right now I have another tote that I prepare the new water and nutes in and two extra air stones and tubes once the water is right I just switch the lid. It seems like that may be hard to do with them sticking through a net. will I need to take the net down and re scrog each time?
