Looks to me like the lights are going to cook those seedlings at that distance.

Hydroponicshut warned about their lights and seedlings.

fwiw

They're about 5 inches above the tops of the plants. They all seem to be doing fine right now.

This is my small 80w induction lighting grow. I might be adding a small CFL or even a small LED light later on but for right now I just have the two 40w induction lights up. One is 6500k and the other is 2700k. Since I can only grow two to three plants at a time I decdied that the small induction lights would fit my needs better. It also allows me to keep it quit stealth in my grow box. Plus unlike CFL's they're less than $70 per light. I started with three seeds figuring that at least one of them is going to be male. I built a carbon filter for the fan. Nothing too fancy. So far temps are staying in the high 70's and low 80's. I might have to add another exhaust as summer comes to keep the temps down. The lights add about 10 degrees. Here's a few pics. Hope you all enjoy.




Make sure the lamps are rated for base up operations and take a temp reading right on the plastic housings. Lamp heat can cook the driver components with temps usually over 120 f. Reflectors on these lamps actually trap heat against the driver so be really careful if that's what you try later on. check the mfg ratings for base up and max driver temp so you don't exceed them.

Why the 2700 K? There's no UV on a 2700 and right now that's the spectrum you need.

I have noticed that there's heat in the center of the lamps. I'm working on finding a small fan that I can put in the box and aim at the lights. At the moment I just pop the door open and aim my big fan in there. drops temps to the low 70's high 60's and you can even hold your finger to the glass of the lights.

I went with the 2700k to hit both spectrums. I have noticed that the plants are leaning towards the 6500k one but the 2700k helped with the flowering on my last grow so I wouldn't count it out yet.

Definitely solar radiation contributes both UV and IR but at veg the nodule spacing is increased and the stems are spindly without enough UV energy present.

As to the temp in the center; are these lamps rated for a base up application? The reason I ask is that the area inside the plastic housing is at least 20 degrees hotter then a measurement on the outside of the housing and with the number of hours these will be running you do not want these what are basically a high frequency generators inside the driver housings burning up mid grow.

Well I got them from http://www.inductionlamps.com/ but I did find a place that had 80w ones for around the same price, I just can't remember the site. They aren't the mushroom shape though which I kinda like. They only weight about 2 or 3 pounds each. They didn't make any comparison to HPS lights. I don't think they'd thought of them as grow lights yet. I will say this, having used CFL's before this is definitely much brighter.

Glad to have you all along for the ride. I'm excited to get this grow going. So far everything is going well. I've got the lights about 4 inches above the two big pots. The little cup is just chill'n in the middle basking on the outer foot print of both lights. Right now they're on 24 hour light but I'm going to do the first dark cycle tuesday when I get off work. I'll do 20/4 and then a few days after do 18/6 and stick with that till veg.

I checked out the website to try and get more info on the lamps you're using but I didn't see them listed as 80 watts ea only 40 ea so I take it the 80 watts is a total load with both lamps running. Is that correct?

I did see the hydroponic lights though from 80 to 150 watts as a complete fixture. You won't see the link from the home page for these you have to go to 'applications' Did you consider these?

Well so far everything is going great. They just woke up from their first 6 hour dark period. The lights are running great so far. Temps are stable. Here's the pics. The bag seeds are the cup and the one on the right.

Hey Steve, you seedlings really don't need all that light just yet. When they are 3 weeks old I would add that 2700k light. They are growing good but I don't want to see you burn your babies.

Well so far everything is going great. The bag seed has really taken off though the one in the cup has stretched a bit (it sits a little lower than the other two). The AK is growing nicely just not as fast. I have noticed that the plants tend to lean toward the 6500k light. My guess is that it's because it's the spectrum they love at this point. I'm thinking for my next grow I'll do 2 of each spectrum for veg and flower. This will also give me a reason to add the small CFL I wanted to. From what I've been told plants grow best with a full spectrum. It may not need much of the 2700k spectrum right now but it doesn't hurt to have it there. So my next grow will start with 2 induction 6500k's and a small 2700k CFL and then switch them for flowering.

Oh and from what tinkering I've done I'd say between 3 and 5 inches is the perfect height for these lights. They don't burn the plants at all and they don't seem to stretch. Temps are still holding in the high 70's and low 80's inside. I'll post pics in a few days. Everyone have a great weekend.

Nice! I was thinking the range might cause the opposite of stretching due to the intensity of EFDL, but if you start to see fat fan blades with little vertical growth you'll know for sure hehe. Can't wait to see how things go! Induction works! :)

Be prepared to add more wattage as the intensity on the plants within the proper UV spectrum is vital.

500 umoles over 12 hours is optimal.

Are you measuring the light levels at the plant?

Well today is day 13 of veg. So far things are going well. The bag seeds are the one in the cup and the pot on the right. The one in the cup is smaller than the other two. I'm thinking I'm going to put something under it to bring it closer to the lights. The bag seed in the pot is still the biggest one so far. It's starting the 4th node already. Both the AK and the cup bagseed are working on their 3rd.

any guesses what the bag seed might be? The leaves are coming in nice and fat so my guess is indica.

Well so far the two in the pots are going great. The cup is not doing so well. Staying realy small. So based on this I"ve decided one plant per light should be about right. Once again the bag seed is on the right.

In case any of you are curious I do rotate them I just happen to take pics when she's over there. The bag seed grew into the light a litle when I wasn't looking and got a small burn.

I'm going to switch them into 12/12 either on day 20 or 25 I'm thinking. Right now they're on their 4th and 5th node production. I'm not sure if I want to top. Never done it before but it might be good for keeping these things shorter for the box.

The lights have been performing wonderfully. Temps are staying in the high 70's and low 80's. The new box so far is far superior to the old box and lights. I'm just going to stick to two plants form now on. Here's the pics.

Topping is pretty much my favorite thing. I think you can somewhat shape the way you want your plants to grow via topping. I have found through a few grows that I much prefer topping solo, instead of LST or LST + topping.

It's pretty simple after that first time when you see what you need to do. You would be better topping while still vegging, so I like to let mine grow the node, and then get some growth before topping. It seems if you wait till right after the node forms where you cut, if you do it too soon it kinda stresses the plant quite a bit.

I'll also be starting a few solos shortly with a bunch of bagseed as well.

Looking good man. One suggestion is to remove your carbon filter until flower. This will help keep your temps down some, plus there will be more air circulated. Your plant typically wont smell until its mature. Also if you haven't already i'd either double up the exhaust or put a small computer fan on the intake side pushing air in. Just my opinion though, Keep up the good work!

Well I'm not really worried about temps. They are staying in a healthy area right now. I also open the door and have a desk fan blow the plants around for 5 hours a day. The stems are going to be nice and strong. I might add another exhaust if I put in the third light I'm thinking of. But only if it's a CFL. I might get one of those small LED spotlight ones. I'm reading up on how well they do as supplimental lighting. If you have any experience with them feel free to chime in. :)

Oh and just from a building stand point you actually want fans for exhaust and not intake. The reason being is you want suction. That way the smell doesn't leak out it has to go through the filters. In my last box I had the fans pushing out the filters and it just caused problems. Having passive intake and then filter and then the exhaust fan gives it much stronger air flow. I guess it's easier to pull than push.

Yep, having negative pressure inside a case is always cooler. This is the same for cooling the components inside your PC as for your grow box.

Just started the girls on 12/12 today. The one in the cup did not make it but the two in the pots are doing great. I'll grab some pics when they wake up.

Okay I was distracted last night by strippers and booze. Here are the pics from day 21. They just woke up from their first 12 hour dark period. This time the bag seed is on the left under the 6500k light. Hope everyone has a great weekend.

EDIT: Oh and you may have noticed the cup is gone. After 21 days it had not developed beyond the second node. I'll be sticking with two plant grows unless I make a larger grow space and can provide a 3rd light. hopefully it was the male.

Well it's been a little while since I posted pics so here we go. The bagseed is on the right this time. The lights have been working wonderfully. So far the growth is much better than when I just used CFL's. Temps are still holding in the high 70's and low 80's. Well not much to do until they show me their genitals.
