Bayer Complete @ 1ml per gallon for 3-5 days.

If you run at 120vac, wouldn't be a bad idea to set a fan on top of the fins. Gavita ballasts run damned hot on 120vac without a fan....like 140F at the surface. Higher frequency = more heat.

I figure a fully seeded plant weighs on the order of a third more than an unseeded plant. That's a lot of mass that is not normally going to be produced. Therefore, the plant doesn't need all those fan leaves. Despite that fact, wholesale defoliation is a bad idea. What you want to do is start...

As to the Gavita graph that you continue to disparage, what exactly is your problem with it? I'd say the data looks to be in-line with expectations of the represented equipment. Furthermore, the equipment being compared is all Gavita. How is that a "sales tool"? With indoor gardening, it is...

"Air chambers" is perhaps not the best way to describe it, but the condenser is reasonably well insulated from the outside air section which contains the evaporator. Most window units also have a small vent that can be opened to suck in outside air should the user desire it. Problem is, window...

The laws of physics are still intact. As previously stated, a 1000w Digistar DE bulb dimmed to 600w outperforms a 600w Phantom SE bulb (USHIO). This is exactly as expected since the Digistar is operating at a higher frequency than the Phantom. All of the equipment used for this test is top notch...

That is not what I stated at all. Would you care to reference that? What I said is that Gavita attaches the ballast directly to the reflector to eliminate RFI. Bigger wires? I've been doing electronic/electrical work for years in a professional capacity. The cable sizes supplied by the...

Where are you getting this shielded cable from? I haven't seen any in this industry. Done right, it ain't cheap.

No, I am going to take some simple intensity readings. Because that is all that is needed. Edit: Nice chart, BTW. Looks like about a 21% difference between the 600w DE bulb and the 1000w DE bulb dimmed to 600w. Drop the 1000w bulb down about 4" and I'll bet they'd be equal.

RFI became a well-known issue due to the high frequency generated by the Lumatek and Micromole (AKA Gavita Digistar) 1000w ballasts. These ballasts were specifically engineered to produce high frequency output in order to produce more light from SE bulbs than competing ballasts. This is what set...

You have run EVERY double ended bulb AND hood? Sorry, I find that doubtful. As for dimming, of course the lumens are affected...you are putting less power to the bulb! Although I have not checked it with a meter (yet), I am convinced that a 1000w Plantmax DE bulb on a Gavita dimmed to 600w is...

Have either of you actually used a Gavita Digistar 1000w ballast? The DE bulbs operate differently than SE bulbs due to the high frequency excitation provided by the ballast. The loss of efficiency by dimming - if any - is not significant. The bulb runs plenty hot, dimmed or not. If there is a...

Get 2 Gavita Digistar 1000w ballasts and use hydrofarm DE wing reflectors. With the DE bulbs, you can dial down without loss of efficiency and/or bulb life. Plus, they put out more light than same wattage SE bulbs. Digistar can run on 120/240VAC (but set about a 20w fan on top of them if you use...

I recently received orders from both Hemp Depot and PeakSeedsBC. I can't remember if HD had a declaration but the PSBC package did have one. I also ordered from Hemp Depot a few years ago. All of these orders were received with no problem. As you noted, I can't remember anybody complaining...

What makes you think so? All incoming mail goes through US Customs and that most certainly includes Canada.

Mexican Sativa. But you will likely have to find the proper phenotype for it. MS effects can vary quite a bit. Edit: my latest foray into MS land was a bust; an emergency prevented completion. The brand was Sensi Seeds. They are claiming an indica backcross but I question that. Out of ten...

One of the problems with various potting soils is that the bags have little vent holes in them. The bugs can come in one product and then migrate to another. This happened at a local grow shop. I switched to pro-mix bx (completely sealed bag) and botanicare coco large compressed blocks (also...

You don't need the flora grow. What is your soil/amendments?

Symptoms I had were leaf yellowing followed by browning out from tip to stem. I verified insects with a strong magnifier and a soil sample. The mites are very tiny, smaller than a period on a white sheet of paper. They will likely be on topside of the soil/rim of container as well as in the...

Could be root mites/aphids. The timing is about right.
