Mr-Foxx you should keep your reservoir outside of the tent, that the plants are growing in, and just run a piece of piping into your plants through one of the low to the ground intake air sleeve's! Where you would put your ducting through! This helps to keep your water temperature lower, and will stop any of the intense light from your lighting from being able to leak into your reservoir as well! Warmer water temps and any light leaks you will add up to algae and and root rot happening in your DWC! Also depending on how hot your house gets in the summer, You may have to get yourself a water chiller! Cannabis is not too fond of growing in warm water, and any algae, fungi's, or not beneficial bacteria's etc... Love to grow in warm water! It is another cost that most DWC growers do not take into account when they start growing DWC! Yes it speeds up growth and you will get nice yields too! But there are a ton of things that can fuck up your roots and plants growing DWC! just a heads up!
Also you should try to make your DWC into a recirculating system it helps a ton, to get more oxygen to the roots, more nutrients and keep that water moving so thing have a much harder time at growing inside of your roots and buckets!!! The healthier the better!!
The bigger the roots the bigger the fruits!! Or buds and cola's in our case!! LOL...
