Without being able to look at those two setups (aeroflo and aerojet) in person, I really cant see what additional risks I will be facing when comparing one over the other. But it seems that the aerojet is the superior of the two.Well what sort of height are you working with? Have you considered SCRog, supercrop, or other tactics to increase yields and better utilize your space?
If you want an upgrade from ebb and flow, I would consider a Gen Hydro NFT setup, which is what I'm running now. Sits low on the ground too.
Or of course the Aeroponics setups will definitely be an upgrade and faster growth. Just more risk involved, however if you're very experienced already I'm sure you would be able to handle it.
