INFI's 280W CFL to 150W HPS grow - finally!

First a big thanks to peeps who have helped me directly get some ideas for growing, and also to those who indirectly helped me, by helping provide the best online resource for cannabis growing I've ever seen. Credit where its due guys, your the best lot around and a lovely bunch at that :jump:

OK, I'm going to lay out my grow now, so that you can all see what I'm up to at long bloody last..


Right, the idea.


To start vegging some babies using CFL and then flower under HPS.


Simple really.


OK, the only seeds I had available were Northern Light seeds, straight from the Dam. I managed to germinate these all and put them in tiny pots until they started to push through the top soil, at which point they were transferred to larger 5-6" wide pots. I have some pics somewhere, so I'll post them up later (the fresh sprouts that is)


I seeded, potted using John Innes 1 and 2, and will final pot in 3... the mushroom compost farm near me has retired from business, so gutted there... Innes was fine for me when I grew outdoors, and no probs yet.


My setup at present consists of two large toy boxes upturned... both sprayed white on the inside, although the matt can I used was toilet, so I will be needing to respray when I find the time but the plants look OK so far. For the HPS I have a gas cylinder cabinet on order, which should let me fit 2x11.5" pots in and give at least 40-50cm of grow room, so I'll need to scrog, but it should be fine. That will have 120mm PC fans for better heat movement.. I am aware that the HPS is hot, so may build in a glass shelf like I've seen some LEGEND on here do ;)


Toy box stats are only small;

17.5" x 11.5", and I have about 12" of grow room to play with at present.


I drilled 4 holes in the top of the upturned toy box, and fitted 4 CFL lights... 3x60w and 1x100w, totalling 280w of CFL. The plants are raised up on boxes and DVD's so that they were closer to the lights at the start, but even still there was a little stretching and needed to be within about 2"...

I fitted 2x80mm PC case fans which are running in parallel on a 12v AC DC converter. 1 in, 1 out...


Temps are between 75 and 85 at the most. I don't have a humidity monitor thingy yet, but may get one if its totally necessary. I have been watering as told... only when the first 1" or so of soil is dry, and they are fine at present.

I planted the seeds on the 15th October, they were on 24/7 light for 2 weeks, and have been on 18/6 since, until I decide to 12/12 them.


The plan is to let the 5 babies veg out until I can see who is a lady, and who is going to die very very quickly with some scissors. Once I have the ladies by themselves, I can put them under my HPS... I'm expecting to only maybe get around 2 ladies... but if I jam all 5, I will LST and scrog the other 3 in the toy box keeping them under the CFL's..


A question if I may before the pics! :redface:


1. I am not sure about the 'being able to tell if they are ladies during the veg' bit. I have a feeling that only once they are being flowered that I'll be able to tell whats what?? I've read bits here and there that it can take a week or more to see balls or pistels. I thought putting them on 18/6 would do the trick, but maybe not??


PS - I have the handles to tape up on the toy box (you may see them in the pics), so I'm aware that will need to be plugged up...


Right onto the pics. Any advice or anything, is much appreciated.. Sorry for possible incoherent post... I've just woken up and had some spare time to get this posted!


Plants are at 5.5" high in these pics, taken today..


(sorry for the links, imageshack was playing up)
























Keep on smokin'

Anybody? Have I done something wrong?


you're doing well, don't worry about it :rasta: if they think it needs to be moved, it will

plants are looking good

as far as sexing goes, I prefer to switch them to 12/12 for a few days until they show sex then switch back to veg. some say this causes stress and can lead to hermies, but i have had no problems. you can also just wait until you want to put them all under 12/12 and pull out the males then

oh, and upload the pics using icmag instead of imageshack, it's safer. when you go to post something to the right of the text box click on "Upload Pics"

no, sir, everything is peachy . the plants look good . depending on the plant, you may have to go all the way to 12/12 lighting for it to show sex. i have one strain right now that has been vegging under 18/6 for over 3 months already, and only one of them has shown sex. the previous strain i grew was in a much bigger hurry to show sex while still under 18/6 lighting.

I had very similiar questions regarding when they show sex. I was under the impression that they had to be flowering for a week or two to show sex. But my plant (first grow for me, so be mindful of my lack of expertise =D) just showed one day during 18/6. From what I can gather, timeframes for sex'ing are very strain dependant.

Best advice I know to give (albeit novice advice), just be attentive...and leave the plant alone :dueling:. Blaze up and stare at it for hours until it puts a skirt on...thats what I did. :rasta:
edit: Nice setup btw, I love seeing what people come up with to fit their differant requirements. Gives me ideas! :respect:

some plants are auto flowering, meaning that they will show sex no mater what light cycle there on. be mindful that those strains are quite $$$ but for most everyday potplants they need from 1 to 2 weeks to show sex unless you add ferts that are to speed up flowering and stop streching (humbolts bushmaster and others) but under an 18/8 and for how small those plants are there not going to show sex till later on. for 5.5in how long did you let them veg for? I have 6 plants that I have under a 400w flowering as we speak and its been 3 days and no sign of sex yet. I would rec that you just let them veg for a little while unless you have space issuse. I over worried about my plants at first and I FU badly the first time.
plants 1st day flowering
