Hello everyone on here, i figured instead of introducing myself and asking the question on separate topics, i would get straight to the bottom of things on this one. I have been lurking the forums for years, had multiple accounts some in which were deleted due to inactivity i believe, but aside from that this account has been on here for over a year. I have been registered on multiple forums and if i ever wanted to learn something with good information and accurate facts i come here. Anyways, i am planning on starting my first real grow, (yes, i will have a journal up and ready as soon as my supplies come in, i have started one grow but never finished it due to my anxiety sadly to say) I have the proper materials on list (again not ordered yet) and even more from my fish aquarium (underwater heater, underwater temperature reading, non used airline tubing, 12" airstone, air pump, etc) So instead of chit-chatting away ill start with question number one, 1. I am using a 4 gallon tub with lid, an aeroponics system, say my plants are 12" tall and mounted in the lid, is it bad to lift the lid off the reservoir with plants still on the lid in net pots? I want to be able to check the temperature of the water so i know i am not stunting or growing anything on the roots (too low or to high of a temperature), not only that, i wanna be able to check the root structure, feed them with nutes, and adjust temperature via the under water heater i own. Question number 2. aside from the airstone i am buying with my hydro system, do you thing the 12" inline airstone is to much? besides these two questions, i have done enough research to make this grow successful. thank you for your help and cheers.
