hey phillip how far do you keep each hood apart? in my flower room i have 4 magnum xxxl's i keep them about 3 ft apart. is that too little? should i keep them further apart?

I have the same hoods with 1000w bulbs. I heep mine 6' apart. A 1000w light has a footprint of 5x5 when 18" from your plant canopy. That means 2'6" in all directions from the bulb. You can add a little more when you have 2 lights side by side because the extra foot in the middle is receiving tlight from 2 bulbs which add up to sufficient footcandles.

Hey phil
ive got another question for you: venting my room and cooling lights with an inline set-up, 800cf space. This is the order of setup can 66, 8" inline (720cfm), 8" ducting, 1000w/hps, 8" ducting, 1000w/hps, 8" ducting through a/c vent duct in ceiling. Question is my room is setting pretty steady @86 degrees during the lighting period according to my probe im wondering if i move the inline fan to the end of the lights right before the vent will it work that much more effectively and lower my temp anymore? have 6"ducting along bottom of floor feed with 6"inline(400cfm). Trying anything to not have to run ac and summer is coming in CA soon, any ideas?

Move your fan as close as you can to the ceiling. Mount it on the a/c vent duct if you can. Inline fans are much better if ised to pull air rather than push it. The way you have it set up you are creating positive pressure in your reflectors which is probably pushing hot air into your room.

and this will still be sufficient to pull air through the filter at the opposite end

What kind of fan is it. I would say 90% of all inline fans don't pull their rated CFM's. Some don't even pull half. What brand is yours? If it's a straight shot with just a curve upwrd to the ceiling you should be fine. Get your filter as close to your hood as possible to reduce the ducting run. Take out as many curves as you can in the ducting.

Couple issue I see. You aren't fitting 32 one gallon pots in a 3x3 tent. Maybe 16-20 but not 32. Second, if you veg plants for 4 weeks then you aren't fitting 32 in 5 gallon pots in a 4x8 tent. Those plants will be 4-6' tall and need 2sq.ft. per plant. I wouldn't want to deal with constantly having to move those pots around. The whole point of a perpetual is to not have to do that. Just harvest 1 tray every 2 weeks. A simple solution to your problem is to turn the door to the room around. Have it open outward and you'll have no problem fitting 2 4x8 tents in there.

Ok so then it would be best to jus fill em up tray by tray every two weeks jus transplanting 16 of them from one gals in the veg tent into the trays in the 4x8 tents n jus leaving em in five gals for eight weeks. So next question if im doing four trays at seperate times I need to have different ratios of nutes for all the different stages. do u kno how to set up auto watering like a sprinkler or somethimg

its a hydrofarm 8" rated for 720cfm and im gonna have to have 3 90 here is a ghetto ass drawing i could draft real quick

I'm lost. Why are you putting plants in 5 gallon pots? You said you were growing short plants; maybe SOG. You don't need pots that big to grow short plants. I would veg them for 2 weeks in 1 gallon pots and then transplant them 1 to 3 gallon pots 1 week before you swithc them to flower. That way; depending on the strain you will get 30-36" plants. You can't grow much taller then that. All those bigger tents are at most 7' tall. With a light hanging in there and the distance you need to keep the plants from the light you only have 5' really. Then you have to have tables and reservoirs. You will never need a 5 gallon pot.

If you have 4 trays then you have 4 different nutrient mixes that you are making every week. Your mixes never change. What changes is the reservoir that you add those mixes to. For example...every week you will be mixing a 200-400ppm solution, a 600-800ppm solution, a 1000-1200ppm solution, and a 1000ppm or flush solution. The only thing that will change is every 2 weeks those solution will be going in different reservoirs. You should have a square reservoir under ever tray. Then you would use a water pump, tubing, timer, and drip stakes to feed each plant. Or you could do hydro (clone your plants in rockwool then move them to hydroton) and just flood the tables 3-4 times a day. Either way is very simple.

Get your filter as close as you can to your light. Reduce the ducting distance as much as you can. If it is the green fan you bought off Hydrofarm.com then that is actually an Active Air fan. No offense but those fans are dogshit. I would still make the changes because it is going to help. If you still have problems with the heat afterward then look into a fan that actually does what it is rated for. I would recommend the CAN High Output 8" Inline Fan. Those are what I use and they actually do achieve their rated CFM. I've also heard good things about the Vortex Fans.

phil greatly appreciate it man

I'm here all week. Don't forget to tip your waitress..

My pleasure bud...

Yea thanks phil ur the man ill let u kno and send u some pic when I start to setup the room.

Hey phillip got a ?

That heat exchanger has a baffel that stops the water from moving through! When the therma stat shuts the fans off!
So ho do i setup a pump to shut off during this time, to eliminate it from dead heading and burning up! Any ideas

That's crazy, you sure it isn't just routed to different port? You would think they would let the water continue to run and just shut off the fans. Water pumps are really designed for continuous use anyway. Or at least just have the water routed through an auxiliary port. That's really weird Hell. I'll think about it but I bet the guys at H&M will have a logical answer for you if you call them tomorrow.

Well i did talk to them and they said stuff like re wiring it to run the pump power cord from the unit!
But thats not plug and play as it was sold to be! Guess RV pump can be dead headed so i might look
Into one of those.

That's kinda bogus on their part. I mean they must know you are going to be hooking up a water pump. Any way to trip the relay on the baffle or lock it open? Maybe you could just wire a simple bridge and trick it to think it's always on?

Thats a trick idea i will look into a wiring on it and see

Thanks for the reply Phillip. I have looked more in to a perpetual grow cycle and found a great link on this forum https://www.rollitup.org/hydroponics-aeroponics/6592-get-harvest-every-2-weeks.html. Its alot of pages and just started reading it but am liking the idea and would like your take on it. I was thinking 1 Msq tray with 25x3.4ltr square pots. Sorry to mess you about but taking this into consideration and how the guy has his perpetual grow cycle could you adjust the room/rooms accordingly. I will also read thoroughly through that thread and will update you with any relevant information. Just took into coinsideration that for this style cycle i will need 4 lighting systems so thats 4 x 600 watts. As you know i want to keep the power consumption and costing down. Have i hit a brick wall with trying a perpetual grow?

And from understanding what you are saying with the intakes/ventialtion i will be looking at 3 fans then one to draw in from the window, one to extract from the hoods through the attic and one connected to a carbon filter, is that right? Living in the UK the temperatures are never high sometimes we may get a few days of mid to low 20's (celcius) but the majority of the time its 10 celcius. Winter even colder So taking this into account getting cold air into the room shouldnt be an issue should it and the need of an aircon unit shouldnt be needed? I will be looking at running the lights at night aswell and i would like to mention the temp at night here can get quite low to single figures, even on a hot day 20 celcius the temp can drop below 10 celcius in the night. Also from alot of grow diaries on a UK forum they use parabolic or open hoods would you still stay stick to the vented hoods as outside temperature rarely gets upto mid teens for any length of time. Im not contradicting you just making you aware of the temperatures so i can get the best setup ..

Lastly what are your suggestions for lighting them in Veg? i was looking at maxibright T5's 4' 8way possibly and what lights would you recommend for the mums.

Many thanks again and again

de humidifier was on the list for sure but just didn't want to have to buy an a/c later so I was looking at a 3-1 with de humidier included in case it does get too hot in there at some point. I still haven't tested the tent with the mh light on for 18 hours next to it so I'm not sure if that will affect the heat at all. I know for sure it is going to get hotter up there in july and august so I may as well be ready for the heat!

didn't know about the runoff being good enough for the plants that could be very useful since i need to top off the reservoir on a regular basis anyways.

Just make sure you get one thats rated larger than your room. This will allow it to not run constantly.
The one i went with was ideal air and it plugs 240v so theres savings right there!
