do not place the reservoir anywhere but on the floor. Pump goes “IN the reservoir” to pump water to the tote/s. At the catch basin, you can recirculate the water for a few days but you must keep a watchful on on TPM and PH…Add a spill valve on the catch basin to discard OLD water. Add a second Reservoir to just hold fresh water, like a 55gal drum.
Not sure 8’ is enough height…recommend 10’ or better. If you can float a ceiling, have it vented and place your Light Drivers there, you will keep the heat from them out of the grow room. That is why I said floating ceiling…just a panel you can lift to access the lamps drivers. Yes they daisy chain connect. Not, not 800w ttl, up to 640w per light…5 of these and you are up near 3k WATS…
Per tote, I would not go less than a Spider4000 in SIZE…On the outer edge of the ppd, that is only in the 200 range for 5’…around 500 for 4 feet…They run around 450w. When you compare them, it is almost a break even on cost but 1212 leds vs 3389 and 450w vs 640w…hard to warrant that cost for SO MUCH LESS.
you want 6 feet of space between the light and the TOP of the tote…that is just for plant growth…you should maximize around 5 feet of it…an 8’ ceiling is a MAJOR HAMPER…no commercial or large grower goest this route…If that is your restriction, you are better off tent growing…buy 4 big tents (like 7 high, 5 long minimum 4 wide), 1 light per tent and an exhaust fan and your have a grow environment. You CAN place the driver on TOP of the tent…you segregate your grows so you can grow them in stages / batches based on strain, genus, time to maturity…etc. It will also allow you to protect each smaller environment from the other to prevent: contamination, disease, pest spread, POLLINATION!!!(a biggie - only takes 1 small males sac to ruin an entire grow).
Does not have to be a tent but you could build separate areas about 6’ wide and 7’ high at around 4 feet deep…
you could still daisychain lights, use a manifold watering system setup, connect 2 rooms / tents to 1 air exhaust controller (place between rooms / tents and use a y / splitter to each area)…etc
Water vapor - it is easier to control humidity in a smaller area than a larger one. I had to use 2 commercial dehumidifiers to control 8 lights grow room and had to setup the emptying of the dehumidifiers to be automated, they required emptying twice a day…using totes you will be able to reduce major transpiring so it should be less but ventilation is PARAMOUNT!
Dan, as an old grower, don’t get caught up or head trip and growing and selling…not as easy as it seems and it gets INVOLVED. The more you grow, the more attention it requires. I went from 1 man operation to 5 people and had to hire trimmers at harvest time. It burnt me out. Now I grow for the wife, a friend or 2 and the hobby…back to loving it
It really is involved…a job…like pets, you can’t leave them unattended. They must be tended to EVERY DAY…by you or someone you trust. Only takes 1 bad day to ruin a crop…1 bad reservoir that is tainted (mold, slime, algae, ph off, etc) to take you down. It is why we break them down to smaller pieces, easier to manage.
