So, the girl are growing pretty fast! And here's their roots! The brown/black is worm castings, and the ones that look like they have short roots were taken out of the net pot, so the roots are curled inside the net pot. And the 1/4" drip lines I had running to the buckets were just not good...

But they're different strains and one is starting 3 weeks later and it's more sativa leaning, so I'm probably going to switch it to flower a little later (because the scrog will be 2 weeks behind), and they'll be flushing at different times because of the flower time and when they are switched...

Oh my tents are both going to be at the same stage at the same time due to time constraints at my current location. In the future I will run perpetual but not this time around. So my tents will both be at HPS at the same time. I've got my buckets insulated with a highly reflective material, so...

Trust me, if I could afford the off the shelf chillers I would buy them right now just in case... But I just can't afford that right now. Maybe in the future I can afford a single 1/4HP chiller. Can you think of a way to share that between 2 separate reservoirs? Because $350 for a chiller is...

I run a 10k BTU for my room cooling, and it can hold a steady 70 on the hottest day. The 5k I was talking about would actually be modified into a water chiller, with the evaporator (the super cold radiator) submerged into an antifreeze solution. Then a pump would pump that chilled antifreeze...

5000btu is equal to 2 HP, and the recommended chiller for my res size is 1/10HP. Are you talking about the evaporator of the AC being IN the water, or just the cold air blowing into the tent?

But 2 chillers would cost me over $700. 1 AC unit, 3 water pumps, 2 liquid to liquid heat exchangers, and a couple pump controllers would cost me under $200. I'm not an expert at electronics engineering (no schooling or degree), but I do have a decent knowledge of it and I would be able to...

Oh and if I need a water chiller I'll rig up an old window AC unit or something. That's sooooo much cheaper lol

Don't do what?

The buckets are insulated, and the room is pretty cold. My water usually measures 68 degrees, and I'm going to be adding a microbe tea to my res. So I should be okay without a chiller, but I'll keep an eye on temps and see.

Lighthouse Hydro 4x4x7 tent. It also has a low hole for power wires, but my return lines are hard pipe. Plus the electrical hole faces a wall in my situation. I actually think I won't have a problem with having the res in the tent if I plan out the spacing. I did the same setup in my first tent...

Alright I'll definitely run with that then. I just wish I had a way to run my res outside my tent but it won't work because I'm doing RDWC and I couldn't get the return line out of the tent without cutting a hole in it somewhere.

I've been using Jack's Hydro 5-12-26 and Calcium Nitrate 15.5-0-0 based on a formula another user gave me. But for this grow I want to try to tune my nutes a little more for a veg and flower mix. So if I understand, those numbers are absolute which means if I mix 1 gram of Jack's hydro and 1...

I'm trying to decide if I should use 4 x 5 gallon buckets or 2 x 27 gallon Commander totes to make my RDWC. I'll be running 4 plants either way. The totes make the tubing way easier but also waste more water when I have to change the res.

And what kind of ducting do you use? Because I've found that regular aluminum duct gets tons of holes in it and leaks, and insulated duct can be a pain in the ass to try to maneuver.

So I'm not sure I understand. You're saying I don't need high CFM for extraction, but I do need high CFM for my lights. So that would mean 2 separate loops. And I don't want to run an intake fan for the risk of it being set higher than the exhaust fan and causing smell to be forced out.

Seems simple enough. One more question. I'm gonna have 3 fans for 2 carbon filters and 2 reflectors. The way I've got my current tent set up is with 1 fan for reflector and 1 fan for filter. Should I use 1 fan in the other tent and run the light in series with the filter or should I run the...

The smell isn't the problem. I just don't know how to lean over my plants to get the duct off and change the bulb. Plus I'd have to take the duct tape off and all that nonsense. And yes I plan to run an RDWC with 4 plants due to time constraints for the veg cycle. Hoping for some beasts!

Alright, so that's a nice square hood for a square tent, and it's the same size as a Blockbuster. Definitely could work, but you can't change the bulb without taking off the duct can you?

What 6 inch air cooled reflector would you recommend for $100 or less? I'm looking at the Yield Master II, any others?
