Not my first grow but first grow log!

Okay, here's what the babies look like after their first 12 hour dark cycle...might be wishful thinking but they do look bigger, including Jr (the one sharing the same pot as Leggy #2 (though at this point Leggy #1 & #2 aren't leggy any more! ).

I pruned 2 leaves off Leggy #2 to allow more light on Jr. Since they haven't shown any sign of sex yet, I figured it woulnd't have adverse effects on Leggy #2 (not yet anyway).

Raised the light one rung - a few fan leaves were burned. Did some pruning and watered the plants...gotta be mindful of that "light circle" as the plants get taller and closer to the light; the heat increases as the leaves get closer!

[Pedro de Pacas]

No burns on the leaves this moring, but to be safe I did the 'hand test' at the top of the tallest plant; and the heat felt a bit uncomfortable so I raised the light a few more inches.

I turned Leggy #2's pot around so Jr gets better light exposure (gotta love the names I ended up giving 'em! ). So far KC is still the tallest at 11" , Leggy 2 is second at 8.5", Leggy 1 is third just a smidge above 7", Stubby lives up to its name at all of 4" (considering I wasn't sure it would survive the original light fixture falling on it and burning it badly) and looks much healthier than it originally did (to my relief).

Last but not least, Jr is expanding nicely (sprouted several weeks after the rest, go figure), not very tall (1" if that) but the leaves are getting nice and big. Latest pics!

Couldn't upload all of the pics, here's what Jr looks like:

Pedro, Very Nice Log.

Couple quick questions though. What was the temprature increase when you switched to the 150 watt HPS. It seems you are running in a closed 3x3 room if im not mistaken.

More random thoughts:

• This is day 5 since inducing 12/12, the plants should be showing signs of sex in the next few days. I do believe I see hints of white on KC, but I can't really stick my head in there close enough to see if those are pistils or not.
• I have plenty of flat white paint leftover from another project of a few years ago, but I fear that sticking the babies in there as the paint dries would harm them, so that's out.
• The flat white cardboard makeshift reflectors may or may not be helping, it's hard for me to tell as I have nothing to compare it to. I have found a good supply of emergency blankets for a buck each, same place I found the popcorn bins. 70% reflectivity is better than nothing at all, and if I read my research right, hot spots shouldn't be much of an issue under 150 watts of HPS - if I'm mistaken somebody tell me!

Perhaps I should research flat white cardboard reflectivity? According to the Ask Ed column on Cannabis Culture, some Hydroponic growers use it...but how reflective is it as opposed to flat white paint, mylar, emergency blankets and aluminum foil?

Pedro, Very Nice Log.

Missed your question as I was posting!

Plenty of variables but overall the temps are actually a few degrees cooler after switching to the 150 watt HPS. Keep in mind that I was using one 125 watt CFL (nearly burned my hand trying to unscrew it from its socket too - I couldn't wait to let it cool off) with a second CFL (a 45 watter).

We're talking 170 watts of CFL with built-in ballasts, and the ballast is where the worst of the heat builds up. Does the HPS bulb generate heat? Absolutely, but the heat buildup is actually less since it uses a remote ballast, which is kept outside the wardrobe.

The measurements of the wardrobe are 22.75" X 19.5" X 5'4" give or take. Said wardrobe is near the room AC which keeps the outside temperature in the low 70's while the inner cabs temps hover around 82-84 F with the humidity around 58-64%.

Even after adding the exhaust and passive air intake the temps used to be in the 86 -92F range with the two CFL's, so yeah, no regrets since the switch!

I decided to take a chance, I used one of the emergency blankets and lined the wardrobe walls & door. I removed the cardboard (whaddya know? it was warping!) as well as the blue LED panel. At this stage I want the babies to show sex, so the more reds the better.

Here are pics of the grow rooms as it is as of today, the babies and close-ups of KC...6 days into 12/12 and I still can't tell if it's a girl or not!

Looking good man, My cab is very similiar to yours cept Im using a 400w cool tube MH/HPS light. Bit overkill but im hoping to get some high yeilds. Cant wait till you sex those babies.

[Pedro de Pacas]

Lemme know how yours turns out too! Chit meng, the blanket came loose in some spots due to the suction from the exhaust fan the blanket's touching the plants in some spots aluminium foil tape is garbage!

Looka lika I'm gonna have some refixing to do tomorrow, I don't want to expose the plants to my green CFL for too long. I did stick the LED panel back in there though...more lumens won't go amiss.
