Just got my 90 gallon going using this method. I have 4 pots of hc split up all over the substrate. Im running 2x 150 8k mh about 12" above the tank surface. the top is covered with thick acrylic. I havent noticed much growth in the last 5 days. I did notice some of the leaves browning. My sms is wet up to the soil line. It stays very humind in the tank itself. Could it be getting too hot in the tank? Im going to take the temp today after my lights kick off.
