First post, reservoir positioning

So great to be a member, I have been lurking on and off for a while. I am planning a flood and drain setup and won't have room in my tent for the res. unless I place it under my flood table. Is this the best method. Table is 3x3, I guess I should have the res. outside of the tent so that it stays cool. Would I then need to have my table on a platform so it can gravity feed the water back? My tent is just over 6ft tall and I don't want the table up too high for fear of not having enough space between light and plant. Light is 400watt

Thanks

Yes you should have the res. outside the tent so it stays cool. and yes you will need to put the tray on a platform so it drains back in.
